Leaves to 270 cm long, erect to weakly arching. Petioles 60–100 cm long, aculeate, prickles 3–5 mm long, dark brown; pneumathodes to 10 × 1 mm, inconspicuously brown in dried material, whitish in fresh material; without adventitious (aphlebioid) pinnae at the petiole bases; petiole scales lanceolate, 25.0–32.0 × 2.5–4.0 mm, their tips straight to falcate, twisted, concordantly to discordantly bicolorous, shiny dark brown, with whitish margins and regular dark brown teeth; colors mostly sharply contrasted; petiole scurf a matted tomentum of small branched hairs and dissected squamules 0.2–0.4 mm long, yellowish white with brown parts, white in general aspect, soon caduceus, persistent between prickles. Blades 100–160 × 60–100 cm, bipinnate-pinnatifid, elliptic to obovate, chartaceous to subcoriaceous; dark olive-green adaxially, often blackish when dried, olive-green abaxially; apices ± gradually reduced. Rachises inermous or proximally aculeate, stramineous to yellowish brown on both sides; adaxially with antrorsely curved uniseriate hairs 0.5–1.0 mm long, abaxially glabrous except for scurf remnants, containing appressed, white trichomoidia and dissected squamules (0.2–0.5 mm). Largest pinnae 50–65 cm long, pinnae 10–15 pairs per leaf, sessile to stalked to 0.5 cm, alternate, ascending, distally broadly green alate, the distal segments decurrently adnate before ending in pinnatifid terminal segments; basal pinna pairs much smaller than medial pinnae, reflexed. Costae inermous, to 2.0–3.0 mm wide, adaxially with antrorsely curved uniseriate hairs 0.5–1.0 mm long, abaxially with scurf like on the rachises and scattered pale brown squamules, insertions into rachises abaxially weakly swollen, each with an inconspicuous planar pneumathode, dark brown, elliptic, to 2.0 × 1.0 mm, area around it often black in dried specimens. Largest pinnules 7.5–9.0(–13.5) × (1.3–)1.5–1.8(– 2.0) cm, sessile to subsessile, articulate, alternate, 1.5–2.0 cm between the stalks, linear-oblong, incised to ½ or more of their width, bases truncate to weakly cordate, tapering from the middle to attenuate tips; costules with flat lanceolate bicolorous scales to 3 × 2 mm and bullate squamules to 0.5–1.0 mm long with entire margins and long acute tips, varying in color from tan to deep brown, usually with white tips; costules basally with a black ring going all around their bases (abscission layer); segments oblong, to 5.0–15.0 × 3.0(–7.0) mm, patent to ascending, straight to distally weakly falcate, with entire to weakly dentate margins, tips rounded to obtuse, rarely acute and then margins weakly dentate; basal segments opposite to alternate, the lowest ones not remote from each other, sinuses triangular, acute, 1.0–2.0 mm wide, sometimes occluded; veins prominent abaxially and adaxially, midveins strongly so and adaxially ridged, lateral veins ending at segment margins; midveins yellowish brown abaxially and adaxially, lateral veins yellowish to greenish brown or blackish; glabrous adaxially except for occasional single hairs on the midveins, abaxially glabrous or with squamules and trichomidia like on the costules (squamules on midveins darker or more strongly bicolorous than those on the costules), trichomidia sometimes also between the veins; sterile and fertile veins mostly simple, rarely forked. Sori (0.8–)1.0– 1.5 mm diam., medial and parallel to the midveins, or tapering to a subproximal position towards the segment tips (V-shape), on the back of veins, indusia absent; receptacles globose to ellipsoid, 0.3–0.4 mm diam.; paraphyses few to numerous, hyaline, tan to brown, shorter than sporangia (0.2–0.3 mm). Spores not examined.</p><p>Distribution and ecology</p><p>Peru and Bolivia (Fig. 2A) at elevations of 700–2000 m a.s.l. in the understory of humid mountain forests.</p><p>Remarks</p><p>Cyathea dombeyi and C. pungens differ significantly in the overall appearance of the plants and the shape of the pinnules (compare Figs 3 and 8). In fresh material with intact sori, the different position of the soral lines in these two species is even more evident, which are closer to the midveins in C. dombeyi and closer to the margins in C. pungens .</p><p>The type of Alsophila floribunda (Spruce 4715) was identified as a mixture of different species by Barrington (1978); the specimen P00642346 has a corresponding label, excluding the upper left pinna as belonging to C. pungens (as Trichipteris procera) and referring the rest correctly to C. dombeyi . However, the Kew material belongs to a third morphospecies with remotely postioned, blunt pinnules and abundant whitish bullate squamules below on veins and costules, which is clearly the condition described by Hooker &amp; Baker (1874) for A. floribunda . We separate this taxon from C. dombeyi and transfer with it another synonym, Alsophila bulligera Rosenst. More material of the type collection of A. floribunda (Spruce 4715) can be identified as C. pycnocarpa, another synonym of C. dombeyi here reinstated. This means that the otherwise reliable Richard Spruce mixed at least four invididuals, each representing a different morphotype (and likely true species), under one number.</p></div>	https://treatment.plazi.org/id/163C91782806BC3BFD9CBB5BF5E05065	Public Domain	No known copyright restrictions apply.

Ɨ with pale sub-bullate squamules in rachis axil, lower costules with dark brown bullate and flat squamules, the larger ones with white margins; petiole scales with relatively wide white margins, dark brown teeth scattered.</p><p>The isolectotype has the original label by Spruce stating “I have not seen this growing; two imperfect fronds were brot. [sic] me - they seemed to have been about 4 feet long”. The amount and variation of the existing material suggests that Spruce has used more than these two original leaves.</p><p>Described by Hooker as having sessile blunt pinnules incised ⅓–½, medial sori and abundant minute pale scales on the veins and rachis abaxially. The excluded type material differs in one or more of these characters: Cyathea pycnocarpa has almost subentire pinnules; Cyathea dombeyi has such deeply incised pinnules but with tapering tips and the squamules below are not as notably pale as in C. floribunda . This mixture probably answers the question how Spruce managed to generate so many duplicates of each number. In this particular case, the different collection dates and localities are clear indicators that several individuals were combined under one catalogue number.</p><p>The type material of the synonym Alsophila bulligera lacks the petiole (as does that of Alsophila floribunda) but at least enough material is present to indicate a tapering blade base and a more or less gradually reduced blade apex. The type collections of both names appear very differenct at first glance, because most pinnules in A. floribunda are remote from each other whereas those of A. bulligera are close, with almost no gap between them. In pinnule length and distance as measured from costule to costule, however, both types are very similar. Fertile pinnules tend to be narrower than sterile ones in this taxon, and the different appearances stem from the fact that the material of A. floribunda is fully fertile, and that of A. bulligera predominantly sterile.</p></div>	https://treatment.plazi.org/id/163C91782805BC3EFDC7BAE5F4505621	Public Domain	No known copyright restrictions apply.

Spores not examined.</p><p>Distribution and ecology</p><p>Colombia (Sierra Nevada de Sta. Marta, Cordillera Oriental) and Venezuela at elevations of 600–1700 m a.s.l., predominantly in lower montane forest with Caribbean influence.</p><p>Remarks</p><p>The type of Alsophila obtusa at Berlin has conflicting label information concerning the provenance (“Columbien” vs “ Venezuela ”) and the collection date (15 Jan. 1852 vs 23 Jul. 1855). The latter conflict may be interpreted as two separate samplings of the same cultivated plant, which were brought to Germany by H. Karsten. Other plants of this species were cultivated at Dresden Botanical Garden (1862, Anonymous s.n.; MO-3304121). The type consists of several pinnae, rachis parts and one petiole, but larger petiole scales or a blade apex are not preserved. The only fertile pinna is mounted face-down but the zig-zag-pattern of the sori can be recognized as impressions thorugh the laminar tissue. The type is also comparatively small and pale. Some representative collections that fill the gaps are Ortega Mendoza &amp; Smith 2492 (NY), which matches the type in size and proportion of pinnae and pinnules, but has a darker, dull orange-brown color in petiole and rachis, and Meier et al. 11303 (UC), which seems to represent a stouter plant with pinnule tips not rounded but tapering to a tounge-shaped lobe.</p><p>Cyathea klotzschiana is distinguished in the field from the similar sympatric C. oblonga (both have dark castaneous petiole scales with narrow white margins and blunt pinnules, similar pinnae sizes and numbers) by the different soral lines (submarginal lines, or zig-zag-pattern in C. klotzschiana vs parallel to midveins in C. oblonga) and color of the laminar indument (pale vs dark brown). Cyathea klotzschiana further has small erect, villose hairs on the costae and costules abaxially; C. oblonga has only brown appressed hairs on the veins and costules, mixed with short ribbon-like squamules.</p><p>Cyathea klotzschiana shows distinct variations in its key distinguishing characters related to age, environment, and region. The speciesʼ range spans across the Cordillera de la Costa and the Andes of Venezuela to Colombian Cordillera Oriental and Sierra Nevada de Santa Marta; most of these mountain ranges, though mostly contingent, fall into several subsets of ranges that act as separate biogeographic units, which is supported by the occurrence of local endemic species (e.g., C. barringtonii and C. venezuelensis; Lehnert &amp; Weigand 2017). This is reflected in regional morphotypes of Cyathea klotzschiana . For example, whereas plants from Serra do Aroa (Yaracuy state, Venezuela) have elongate blunt tipped pinnules with pale laminar squamules, which are here considered best fitting the type specimen, plants to the east in the Cordillera de la Costa have more bicolorous laminar squamules but do not differ in pinnule shape. Specimens from Santa Marta, Colombia, to the west, however, appear superficially different because of their exceptionally long pointed pinnules, but are just as pale-scaled as the plants from Serra do Aroa. Also, the short hairs abaxially on costae and costules can be lost in older leaves, which can make it hard to distinguish such plants of C. klotzschiana from C. pungens with sessile pinnules.</p><p>Among the reinstated taxa, Cyathea klotzschiana and C. floribunda are the most similar to each other regarding pinnule shape and laminar indument, with both often having a relatively dense strip of whitish bullate squamules on the costules abaxially. However, the faint leaf dimorphism of C. floribunda is not observed in C. klotzschiana . Both taxa are geographically separated over a large part of the northern Andes by the range of C. pastazensis .</p></div>	https://treatment.plazi.org/id/163C91782800BC22FDBABC22F454534D	Public Domain	No known copyright restrictions apply.

Caravalho et al. 320, INPA) have bipinnate-pinnatifid blades with stalked pinnules (Carvalho et al. 2012), ultimately giving Cyathea neblinae the same variability in laminar disscection as C. pungens s. str .. Both species are also practically identical in petiole scale shape and color, laminar texture and color of the leaf axes, thus C. neblinae might be interpreted as a special dwarf form of C. pungens . However, there are some constant characters that make C. neblinae visibly different: the blade apex seems to be always gradually reduced (vs mostly subconform in C. pungens); all plants described as C. neblinae (Smith 1990) have pinnules with more strongly cuneate bases than C. pungens, irrespective of their size and degree of further dissection. In parts of the blade that mark the transition between simply pinnate and fully bipinnate, C. neblinae has remote adnate segments that are separated wide, assymmetric angular sinuses, formed by the decurrently alate bases at the basiscopic side of the segments. In direct comparison, such transitory sinuses are closer and more symmetric in C. pungens .</p></div>	https://treatment.plazi.org/id/163C9178281CBC23FDACB9CEF5CA57F5	Public Domain	No known copyright restrictions apply.

Largest pinnae 37–45 cm long, sessile or stalked to 1.5 cm (proximal basiscopic pinnule reduced or fallen off), pinnae patent to weakly ascending, distally narrowly to broadly green alate, the pinnatifid terminal segment shortly decurrent into the costae.

The highest number of pinna pairs is twice the average for the species and might have been intended as “24 pinnae in pairs”. Cyathea oblonga was resurrected from the synonymy of a loosely conceived C. pungens by Cremers &amp; Boudrie (2007) based on their field observations in French Guiana. Here, both species overlap in their distribution, and show consistent differences in the anatomy and distribution of the petiole scales (relatively narrow, shiny dark brown with white margins, all along the petioles without getting paler in C. oblonga vs petiole scales usually restricted to petiole bases or if reaching further up then becoming paler to almost white in C. pungens) and the laminar indument (bullate squamules and scurf remnants on costae and costules brown to dark brown, well represented vs scurf and bullate squamules pale brown to white, scant).</p><p>Cyathea oblonga from higher elevations at the tablemountain bases differs from those in the lowlands of eastern Guayanan in having the axes abaxially not atropurpureous but stramineous to orange brown, and being stouter plants with thicker axes and larger pinnules. Plants here reported from northern Venezuela and the Andes of Colombia look more like the stouter tablemountain variety, and although having the diagnostic characters of that species (± medial sori, narrow petiole scales extending to the rachis), they may turn out to be aberrations of other taxa (mostly C. klotzschiana, presumably) after more scrutinous investigation in the field.</p><p>Precociously fertile plants with less divided blades than regular fertile plants are the basis for the synonym Alsophila gleasonii . Here, also the petiole scales tend to be smaller, but full in proportion to the smaller size of the plants. These individuals look like non-sympatric dwarf species of Cyathea, such as C. pseudonanna Lellinger from Panama, which is best distinguished by the denser, stiffer hairs abaxially on the rachises and the bluish sheen of the adaxial laminar side in fresh material.</p></div>	https://treatment.plazi.org/id/163C9178281DBC27FD93BE75F24D518D	Public Domain	No known copyright restrictions apply.

Petioles 20–45(–59) cm long, sparsely aculeate, prickles to 3 mm long, dark yellowish brown to stramineous, sometimes basally darker brown; aerophores to 20 × 1 mm, in a ± continuous line on each side, inconspicuous in dried material, whitish in fresh material; without remote (aphlebioid) pinnae at the petiole bases; petiole scales 20.0–32.0 × 2.5–5.0 mm, lanceolate to ovate-lanceolate, tapering to linear tips, straight to falcate, weakly twisted, concordantly bicolorous, shiny dark brown to castaneous, with narrow, often abraded whitish margins, scales persistent in distal petiole parts, often reaching lower rachis, here only smaller than lower ones, remaining concordantly bicolorous (never paler or almost completely white); petiole scurf a tomentum of small branched clavate hairs 0.2–0.4 mm long, tan with brown parts, dark brown in general aspect, appearing as small dark dots or irregular stars on the yellowish brown epidermis, persistent but easily abraded.Blades (110–)180–255 × 90–105 cm, bipinnate-pinnatifid, ovate-elliptic to obovate, chartaceous; dark olive-green adaxially, often blackish when dried, olive green abaxially; smaller plants with long petioles and ovate-elliptic blades with 8–10 pinna pairs, basal ones ca ½ the length of longest pinnae, larger plants with short petioles and basally tapering blades with 16–18 pinna pairs, basal ones ca ⅓ the length of longest pinnae, patent to weakly reflexed; pinnae alternate; apices gradually reduced. Leaf axes (rachises, costae and costules) stramineous to yellowish brown on both sides, sparsely aculate in lower half, otherwise inermous; adaxially with antrorsely curved uniseriate, reddish brown hairs 0.5–1.0 mm long, abaxially with scurf remnants, costae and costules also with dark brown, erect shell-like to bullate squamules, 0.5–1.0 × 0.5 mm with subulate, rarely flattened or elongate tips, larger flat squamules to 2 × 1 mm rare or absent; junctions rachises/costae abaxially weakly swollen, each with an inconspicuous planar pneumathode, dark brown, elliptic, to 4.0 × 2.5 mm, area around it often black in dried specimens (foliar nectary). Largest pinnae 37–45 cm long, sessile (appearing stalked if proximal basiscopic pinnule fallen off), pinnae patent to weakly ascending, distally narrowly to broadly green alate, the pinnatifid terminal segment shortly decurrent into the costae. Largest pinnules 8.0–11.5 × 2.0– 2.5 cm, linear-oblong to linear-lanceolate, incised to ½ or more of their width (usually 2–3 mm between sinuses and costules), sessile, bases on smaller ones truncate to weakly cuneate, in larger ones truncate to weakly cordate, smaller pinnules (especially in lower pinna) with obtuse to rounded tip, larger pinnules tapering from beyond the middle to short-attenuate tips; costules basally with a black ring going all around their bases (abscission layer); largest segments 12.0–15.0 × 2.5–4.0 mm, oblong, patent to ascending, distally weakly falcate, with entire to weakly dentate margins, tips rounded to obtuse; basal segments alternate, the lowest ones not remote from each other, sinuses narrowly triangular to elliptic, acute, to 1.0 mm wide, sometimes closed; veins prominent abaxially and adaxially, midveins adaxially ridged, veins ending in cartilaginous segment margins; midveins yellowish brown abaxially and adaxially, lateral veins yellowish to greenish brown or blackish, glabrous adaxially except for occasional single hairs on the midveins, abaxially glabrous except for some dark brown bullate squamules and trichomidia on midveins, absent between the veins; sterile and fertile veins mostly simple, regularly forked in the tips of lager segments.

Spores not examined.</p><p>Distribution and ecology</p><p>Colombia (Cordilleras Occidental and Central), Ecuador and northern Peru (eastern Andean slopes) (Fig. 2B) at elevations of (310–) 850–1600 m a.s.l., dubious records also from the western escarpment (Ecuador: El Oro; Colombia: Chocó); in the understory of lower montane forest, preferably in small valleys (quebradas) and near water courses.</p><p>Remarks</p><p>The syntypes of Alsophila pastazensis have been regarded to represent one species, but we consider them to belong to at least two species, one of them Cyathea tortuosa R.C.Moran. This is supported by recent observations by the first author at the Jardin Botanico las Orquideas, a private reserve near Puyo, Ecuador. Both species grew only a few meters apart in the dense forest understory, but each with a specific habit, with C. pastazensis having a trunk covered in old petiole bases and funnel shaped crown, and C. tortuosa with a clean-shed trunk and patent leaves.</p><p>Cyathea pastazensis is best described as a Cyathea floribunda with darker, concolorous squamules on the blades because both have sessile pinnae and round-tipped segments. However, C. pastazensis shows the typical leaf architecture of C. pungens with the pinnules of the lower pinnae being blunt-tipped whereas the pinnules of the distal pinnae are decidedly more acute (vs all equally blunt-tipped in C. floribunda, as observed so far). In the contact zone of the ranges of both species in southern Ecuador and northern Peru, it almost looks like a fluid transition between the two morphologies in a large shared range (Fig. 2B); but as we interpret it, C. pastazensis extends south along the lowland forests of the Amazon basin whereas C. floribunda reaches north along the Andean foothills.</p><p>Both Cyathea pastazensis and C. floribunda differ from C. pungens in soral lines that follow the midveins, thus forming parallel lines across the whole pinnule; in C. pungens, the soral lines are parallel to the segment margins, thus shaped in a zig-zag pattern across the whole pinnule. In C. pastazensis and C. floribunda, pinnae and pinnules are sessile whereas in C. pungens, at least the largest pinnae are clearly stalked, creating a visible gap between rachis and blade; pinnules tend to be remote from the costae, too, but this character is more clearly developed in eastern Amazonian population of C. pungens .</p><p>Cyathea werffii grows in the same region (e.g., Baker 5699, MO, NY), but has smaller leaves with stalked lower pinnae (vs all sessile in C. pastazensis), smaller pinnules with blunt, often widened tips, appearing almost rectangular; it also has scarcer scaly indument on the axes than C. pastazensis .</p></div>	https://treatment.plazi.org/id/163C91782819BC2AFDECBB8DF289542F	Public Domain	No known copyright restrictions apply.

Paixão 1574; NY .</p><p>Description</p><p>Trunks 0.7–1.5 m tall, ca 8–10 cm diam., with old petiole bases, straight to decumbent; without adventitious buds. Petioles ca 35–50 cm long, inermous to sparsely muricate, brown to dark purpureous, matte; scurf absent. Petiole scales lanceolate, 14.0–20.0 × 4.0– 4.5 mm, their tips straight, concolorous yellowish to white, sometimes with dark central stipe, auburn to dark brown. Leaves to 230 cm long; patent and distally arching. Blades to ca 180 × 90–120 cm, bipinnate-pinnatifid, firm herbaceous to chartaceous; dark shiny green adaxially, often blackish when dried, pale olive green abaxially; apices abruptly reduced to a non-conform section. Pinnae to 35–65 cm long, number of pairs per leaf ca 8–10, stalked 1.0– 2.5 cm, patent to ascending, basal pinnae ca ⅔ the length of longest pinnae, patent to weakly reflexed; pinnae distally green alate; distal pinnules free, the pinnatifid terminal segments shortly decurrent into the costae. Leaf axes brown to carnose on both sides, the costules abaxially often blackish; with whitish to brown, antrorsely curved hairs to 0.8 mm long adaxially, abaxially glabrescent with scattered, appressed, tan to brown trichomidia; abaxially with auburn to orange-brown squamules with entire margins and white tips, bullate or flat, 0.4–1.0 mm long; costae inermous, 1.5–3.0 mm wide; insertions of costae into rachises not or only abaxially weakly swollen, without clearly developed pneumathodes, usually blackened in dried specimens. Pinnules to 7.0–11.5 × 1.5–2.0 cm, short stalked to 3 mm, alternate, 1.5–3.0 cm between the stalks; linear-oblong, bases truncate to weakly cordate, long attenuate tips, and with finely serrate margins; incised to ½ or more of their width, with acute sinuses to 2 mm wide, weakly dimorphic, sterile part of pinnae and pinnules wider with narrower, often occluded sinuses; the carnose to brown stalks inarticulate, with a black ring at their bases (abscission layer?), without pneumathodes; segments oblong to deltate, patent to ascending, with subentire to finely crenulate margins, in the latter case weakly revolute; tips straight to weakly falcate, rounded to obtuse; basal segments opposite to alternate, the lowest ones not remote from each other. Veins planar, carnose to dark brown abaxially and adaxially, ending shortly before the segment margins, becoming wider and reddish adaxially; glabrous adaxially, abaxially with appressed, tan trichomidia and thin, hyaline, twisted hairs to 1 mm long, with auburn to orange-brown bullate squamules with entire margins, sometimes larger, flattish squamules to 2 × 1 mm proximally on midveins and on costules; no hairs between veins; sterile simple, fertile veins forked, rarely simple. Sori 0.8(–1.0) mm diam., inframarginal to marginal, parallel to the margins, usually in the forks of veins, indusia absent; receptacles globose to ellipsoid, 0.3–0.4 mm diam., without subtending scales; paraphyses few, hyaline, tan to reddish brown, shorter than the sporangia (0.2 mm). Spores with smooth exospore, finely pitted (Gastony 1979).</p><p>Distribution and ecology</p><p>Northeastern Brazil at elevations of 550–960 m a.s.l., in the understory of Mata Atlântica.</p><p>Remarks</p><p>Cyathea praecincta has been often misidentified as C. pungens when petiole scales are missing (mostly concolorous white in C. praecincta vs strongly bicolorous with white margins in C. pungens), but the whole appearance and coloration of its specimens differs strongly from true C. pungens . Dried specimens have the blades bicolorous, with blackish adaxial side and olive to grayish green abaxial side (vs ± the same color in C. pungens, varying from pale green to brown depending on preservation) and the axes are a homogenous reddish brown to atropurpureus (vs yellowish to pale brown in C. pungens). Cyathea praecincta has many fertile veins forked while they are generally simple in C. pungens . According to our data, both species have clearly separated dstributions (Figs 1–2).</p><p>From Alagoas, we have seen only images of specimens without petiole (W.W. Thomas 12419, MO, NY), which may be C. macrocarpa (C. Presl) Domin. The specimens have the lowest segments slightly smaller than the following in the pinnules, and the margins slightly dentate, which matches more C. macrocarpa than C. praecincta . Cyathea macrocarpa is scatteredly distributed from northeastern Brazil to the Guayana shield (Lehnert 2011). Both species occur together, have submarginal sori and very pale petiole scales, and they are often not distinguishable from photos alone (https://www.inaturalist.org/observations/103467779). A closer look at the sori allows a clear separation as C. praecincta has no indusium, which is easily discernable due to the sparse paraphyses, whereas C. macrocarpa has a dense mass of long persisting paraphyses that hide a well developed hemitelioid indusium.</p></div>	https://treatment.plazi.org/id/163C91782814BC2CFD93BE28F5A75628	Public Domain	No known copyright restrictions apply.

Hoffmannsegg, were collected are unknown. Hoffmannsegg did not travel to Brazil personally but had specimens collected and sent from there by paid collectors (Stresemann 1950). Although an accomplished botanist, Hoffmannsegg seemed to have had his main focus on animals during that time, and documentation of the Brazilian plant material in the literature is scarce. However, most of the plants seem to have been collected by Friedrich Wilhelm Sieber, who was a handyman of Hoffmannsegg, and his itinerary has been researched for the bird specimens he collected (Stresemann 1950). Sieber was almost exclusively active in todayʼs state of Pará, along Rio Amazonas between Obidos and Gurupá, and near “Rio Preto”, which refers most likely to the town of São Benito do Rio Preto in neighboring state Maranhão. One sheet of the type of P. pungens bears a slip with the fragmentary information that it is “fern herb growing low, but if in dry forest at river (Sieber)”, and the type of P. procerum “fern herb, is a real tree, in shape of a ‘palmeiroʼ, in forest at river, its height was more than 6 ells (Sieber)” [personal translation from German], which are vague but still fitting descriptions of the aspect of Cyathea pungens . We may conclude that the types of P. procerum and P. pungens had been collected by Sieber, either in the state of Pará or Maranhão. One of the slips on the type of P. pungens (B 20 0000318) bears a little scribble below the location “ Brazil ” that may be deciphered as “Coto”; there is a location of that name in Maranhão east of São Benito do Rio Preto, which is one of the documented areas that Sieber visited. However, this particular specimen was stored in the Herbarium Link, does not bear any reference to Sieber or Hoffmannsegg, and was only aligned with the Willdenow specimen (B-W 19716) by Hieronymus. The publication of the species names in 1810 is presumably a result from Sieber′s last shipment from Brazil, which arrived in 1809 (Stresemann 1950). This seems rather incredibly fast for the 19 th century, but Hoffmannsegg had a network of keen and active collaborators in Europe who delivered determinations and accounts quickly after receiving specimens (Stresemann 1950). The other providers of Brazilian material sent specimens between 1801 and 1807. If the type specimen of P. pungens had been among them, it likely would have been published sooner. Also, these earlier shipments came from Bahia and Rio de Janeiro, from where C. pungens has only been erroneously reported, based on confusion with similar exindusiate species like C. praecincta (Kunze) Domin or C. atrovirens (Langsd. &amp; Fisch.) Domin. We conclude that the location of the type of Cyathea pungens can be put rather confidently in the lower Amazonas region. Cyathea pungens is widely distributed in the Amazonian lowland (Zuquim et al. 2008), and even with the narrower definition, C. pungens remains quite variable. Most specimens fall into a form with short stalked, asymmetrically based pinnules (including the type of the species) and a form with sessile, ± symmetrical based pinnules (this can be tentatively aligned with the type of the synonym Alsophila infesta). The former seems to be more frequently encountered in eastern Amazonia-Guayana whereas the latter seems to be more dominant in western Amazonia and the Andean foothills; the map (Fig. 1), however, shows no clear regional clustering. Furthermore, small prematurely fertile plants that differ from regular mature plants in having no trunk and only pinnate-pinnatifid to partially bipinnate leaves can be found along the eastern distributional margin, where the tropical lowland rainforests border savannahs and cerrado vegetation, and in the Guayana region (Berry et al. 1995). A fourth morphotype seems to be restricted to open swamps; it is characterized by having small blades, short elongate pinnules with truncate bases and obtuse to short acute tips, and the scant squamules on the costules abaxially are mostly dark brown, all interpreted as adaptations to increased sun exposure; it still has stalked pinnae and often still visibly, albeit short-stalked pinnules. We dubbed these forms as “regular”,”sessile”, “precocious”, and “swamp”, respectively, but give them no taxonomic rank pending further study, preferably with molecular data included.</p><p>In the Caribbean region, including the Lesser Antilles, Trinidad &amp; Tobago, Puerto Rico and Hispaniola, but not on Cuba or Jamaica, there is a variant of C. pungens with both pinnae and pinnules sessile (vs at least lower pinnae stalked in continental South America) but with the typical scant hair and pale squamules on the blades. At first glance, this form is in stark contrast with the Amazonian population and may merit formal recognition below species rank; in lack of an already published name, we refer to it simply as “Caribbean” C. pungens until further studies can clarify its exact status. It is not only found at lower elevations in swamps, which is a typical biotope for the species, but also in sinkholes in limestone areas.</p><p>We keep C. ruttenbergiae from Puerto Rico (Tejedor &amp; Areces-Berazain 2018, 2021) as separate from Caribbean C. pungens for now, although some of its distinguishing features (i.e., stalked pinnae and pinnules) also occur in continental C. pungens . Its bicolorous petiole scales and the pale laminar indument clearly align it with this species, but the branched fertile veins and the general pinnule shape (especially the truncate sinuses between the segments) of C. ruttenbergiae are more reminiscent of C. muricata Willd. from the Lesser Antilles.</p><p>In the Caribbean, Cyathea pungens is less frequent than previous accounts suggested because of widespread confusion with Cyathea aspera (L.) Sw. and its segregates. The latter group is often identical in texture and dissection of the blade to the C. pungens group, but generally has concolorous plain brown to castaneous scales on petioles and blade ( C. pungens has always some elements with whitish color, e.g., petiole scale margins and laminar squamules).</p><p>The central Brazilian specimen Windisch &amp; Oliveira 6493 (US) has exceptionally wide pinnules to 25 mm across with forked fertile veins and medial sori. Regarding the indument and the stalked pinnae, it can be confidently put under C. pungens proper and none of the segregates here proposed, except maybe for Cyathea ruttenbergiae (Tejedor &amp; Areces-Berazain 2018) .</p><p>Some collections from French Guiana (i.e., G. Cremers 6700, G. Cremers 7386 are plants of the regular type but have many short, stout hairs on costae and costules abaxially. Another collection from the same area (J.-J. de Granville et al. 9526) is slightly less hairy than these but still hairier than regular C. pungens, and also having dark, white tipped bullate squamules. Petiole scales are not preserved in this specimen, but the general pinnule shape strongly speaks for C. pungens . These aberrants may either constitute their own variant or their own unrecognized hybrid, though we do not have a suggestion for the potential other parent; an involvement of Cyathea oblonga would explain the squamule color but not the hairiness.</p><p>The specimen Schunke Vigo &amp; Graham 15500 from the Peruvian lowland is a very atypical plant of the “swamp” Cyathea pungens . Due to the small segments, the soral lines appear not to follow the margins in a zig-zag-pattern, as they should, but to be parallel to the midveins. Because of this, a smaller leaf at UC was determined as C. werffii by the first author, but the duplicate at F has a trunk and clearly surpasses the size of that species. Cyathea werffii from the Andean foothills of Ecuador and northern Peru is similar to precociously fertile C. pungens . Both species have been found growing closely together in northern Peru (Chiriaco, Dist. Baeza, Prov. Amazonas; Figs 1, 2A).</p></div>	https://treatment.plazi.org/id/163C91782812BC13FD85BC2BF54A53F3	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

The type of Alsophila pterorachis (Spruce 4717) has serrate pinnule margins, which is atypical for C. pycnocarpa . It is placed here because of the matching overall appearance, pinnule shape and petiole scale morphology. Nevertheless, it may just represent a precociously fertile plant of a different, larger bipinnate-pinnatifid species.</p><p>With its overhanging leaves and subentire pinnules, Cyathea pycnocarpa is a relatively distinct species in the Andes, but not well understood until now. It had been subsumed under either Cyathea pungens (because of the small sori and the general resemblance) or C. dombeyi (because of the presence of small brown teeth in the pale scale margins). The material was long interpreted as precociously fertile plants of C. pungens s. lat.</p><p>As fragmentary specimen, Cyathea pycnocarpa bears a strong resemblance to the Brazilian C. dichromatolepis, where the pinnae are similarly coarsely dissected with entire pinnules and a large pinnatifid apical section. This Brazilian endemic has larger, wider petiole scales with broader white margins. It also reaches larger sizes than C. pycnocarpa, which can already be deduced from the thickness of the petioles and leaf axes. In the field, both species are easily distinguished because C. pycnocarpa has only 5–7 pinna pairs and blades with truncate bases whereas C. dichromatolepis can have twice the number of pinnae and blades with tapering bases.</p><p>Foster &amp; dʼAchille 11548 (F, US) from Madre de Dios, Peru, is a very large specimen with most of the laminar indument relatively dark. Because of the dark squamules, it could be mistaken for C. tortuosa, but that species has white tortuous hairs on the blade abaxially and a dense villous hairs cover on the axes abaxially, which are both absent in this specimen.</p></div>	https://treatment.plazi.org/id/163C9178282DBC16FDE8BA7CF563519B	Public Domain	No known copyright restrictions apply.

Pinnae to 45 cm long, ascending, stalked to 2.5 cm, alternate; pinnules to 12 × 2.5 cm, stalked to 4 mm, inarticulate, 2–3 cm between the stalks, elliptic-lanceolate, bases asymmetric, with a gap or missing segment on one side, tips attenuate with crenulate margins; costules green on both sides, abaxially strongly prominent, ridged, with sparse tortuous white hairs to 1 mm and flat, lanceolate whitish to beige squamules to 1.5 mm. Segments to 15 × 6 mm, basal segments strongly asymmetric, if slightly remote then connected by wide green wing; sinuses oblong to acute to 3.0 mm wide, never occluded; margins crenulate; midveins with few, tortuous, white hairs to 1 mm; veins simple or forked; sori submarginal.

Most notable are the blunt sinuses between the lowest segments of the largest pinnules; the very few samples of C. pungens that have pinnules wider than 2 cm still have acute sinuses between the lowest segments and not the blunt ones of C. ruttenbergiae .</p></div>	https://treatment.plazi.org/id/163C91782828BC17FDD8BB9AF3545000	Public Domain	No known copyright restrictions apply.

Leaves 120–200 cm long. Petioles 20–40 cm long, muricate to weakly aculeate with prickles to 2 mm long, dark brown to blackish, rarely dark stramineous, opaque, basaly with persistent scurf consisting of appressed reddish brown trichomidia and erect, white, lanceolate to ovate squamules to 1 mm long with subentire to erose margins; hairs absent; petioles basally with a discontinuous line of distant aerophores to 6.0 × 1.0 mm on each side, gray brown and inconspicuous in dried material. Petiole scales long lanceolate, to 15.0–25.0 × (1.5–)2.0– 3.5(–4.0) mm, rather thin textured, bases cordate, pseudopeltately attached, apices long attenuate, straight to falcate, often strongly undulate; proximal scales concordantly to discordantly bicolorous, auburn to yellowish brown with white margins, distal ones often almost concolorous stramineous to white with a dark apical streak; differentiated margins without setae or teeth, usually persistent. Blades to 180 × 120– 140 cm, bipinnate-pinnatifid, firm herbaceous, matte, dark-green adaxially, dark olive green abaxially; apices gradually reduced. Rachises inermous to sparsely verrucate proximally, dark brown abaxially and adaxially; pubescent with tan to brown multicellular hairs 1.0– 1.5 mm long, antrorsely curved and persistent adaxially, abaxially glabrescent with few thin hairs and appressed trichomidia, leaving the cortex smooth. Largest pinnae 24–40 cm long, pinnae subsessile or stalked to 1.0(–1.7) cm, 15–20 pairs per leaf, patent to weakly ascending, alternate, inarticulate, distally narrowly green-alate, distal segments simply adnate before ending in a pinnatifid apical section; basal pairs smaller than than the medial pinnae, reflexed. Costae to 1.5–2.0 mm wide, inermous to sparsely verrucate, dark brown to grayish brown abaxially, darker adaxially; glabrous abaxially, with tan to brown, antrorsely curved multicellular hairs 0.5–1.0 mm long adaxially; junctures of costae and rachises not swollen, abaxially often black when dried, each with an inconspicuous planar, elliptic aerophore, to 2 × 1 mm, dark orange-brown. Largest pinnules 45–70 × 11–17 mm, short-stalked to 3 mm, inarticulate, 1.5–2.0(–2.2) cm between the stalks/costules, pinnules lanceolate, rarely linear-oblong, truncate to cordate basally, long-acute to attenuate apically with subentire to weakly crenulate margins; costules dark carnose to dark grayish brown adaxially and abaxially, proximally often darker brown; adaxially strongly prominent, ridged, and densely hairy with tan to brown, antrorsely curved multicellular hairs to 1.0 mm long, abaxially weakly prominent, glabrous or glabrescent with appressed, tan to brown unicellular trichomidia and thin tortuous hairs; also with white to brown squamules, bullate ones to 1.0 mm long, flat lanceolate ones to 3 × 2 mm, with entire margins and short-attenuate tips; costules basally without pneumathodes. Segments to 7.0–10.0 × 3.0–4.0 mm, rarely remote and then connected by laminar tissue, patent to strongly ascending, distally falcate, tips obtuse to rounded, proximal segments alternate to subopposite, usually a bit shorter than following segments; sinuses acute to obtuse, to 1.0(–2.0) mm wide; margins subentire to crenate; margins not differently incised in proximal segments of a pinnule; veins planar on both sides or weakly protruding adaxially, dark carnose to dark grayish brown; veins adaxially glabrous except for some multicellular hairs to 0.5 mm long on the midveins, abaxially glabrous except for some appressed trichomidia; midveins with some pure white to light brown squamules, mostly bullate ones to 1.0 × 0.5 mm; sterile and fertile veins simple or forked. Sori 1.0– 1.2 mm diam., medial to supramedial, indusia lacking; receptacles globose, 0.3–0.4 mm diam., paraphyses few to numerous, stiff, hyaline, tan to brown, shorter than the sporangia (0.2–0.3 mm long). Spores tetrahedral-globose, pale yellow to white, appearing hyaline.</p><p>Distribution and ecology</p><p>Magdalena Valley and Cordillera Oriental of Colombia, Cordillera de la Costa in Venezuela at elevations of 1200–2430(–2740) m a.s.l.; one sterile specimen recorded from Trinidad (Barrington 1978).</p><p>Remarks</p><p>Cyathea squamata has only rarely been confused with C. pungens, despite sharing the diagnostic characters of being exindusiate, having bicolorous brown petiole scales with white margins, and whitish bullate squamules on the blade. Cyathea squamata differs in having more pinna pairs per blade, generally smaller pinnules with notable short stalks and cordate bases, by which means the blade appears more delicate and finely dissected than in C. pungens . Moreover, C. squamata has a mixture of larger and smaller squamules on the axes and veins abaxially, giving it an untidy appearance, whereas the squamules in C. pungens are so small and scarce that they are hardly noticeable.</p></div>	https://treatment.plazi.org/id/163C91782829BC19FDEABA02F5C550B2	Public Domain	No known copyright restrictions apply.

Aguilar 904; F .</p><p>Description</p><p>Trunkless, or trunk to 0.3 m tall, with old petiole bases, 2–4 cm diam., without adventitious shoots. Leaves erect, to 120(–140) cm long. Petioles 35–70 cm (ca ⅓–½ the leaf length), inermous to sparingly muricate, dark brown to blackish at base, green in upper parts, drying to medium brown to yellowish brown; scurf absent to scant, with ephemeral, dust-like white squamellae. Petiole scales narrowly lanceolate, 3–7 × 1–2 mm, discordantly bicolorous, castaneous to brown with whitish margins, erose with some darker cells interspersed. Blades to 50(–100) × 60(–80) cm, obovate-elliptic, with 4-7 pinna pairs (in fully bipinnate-pinnatifid leaves, 15–20 pairs in simply pinnate leaves); apex abruptly reduced. Leaf axes inermous, abaxially with short hairs 0.2–0.4 mm long, scant ephemeral squamules, and small bicolorous lanceolate scales; costae green alate throughout. Largest pinnae 31(–40) × 9(–13) cm, notably stalked by 1–2.5 cm in lower half, sessile in upper parts; basal pinnae ca ½ the length of longest pinnae, stalked by 3 cm, weakly reflexed. Pinnules to 25(–62) × 12(–17) mm, elongate to oblong, smaller ones subentire, largest ones lobed more than half way (to 4 mm) to the costa; bases truncate, tips round to truncate (rarely attenuate in largest pinnules). Costules abaxially with dark brown spot at the base, with hairs like on the costae, with few to many dark brown bullate squamules to 1.0 mm long. Segments/lobes with entire margins, rounded tips. Veins without hairs, or stronger veins adaxially with single translucent or white hairs; sterile and fertile veins simple in bipinnate parts, also forked in simply pinnate parts. Sori ca 1.2 mm diam., ± medial, forming lines across the segments parallel to costules; receptacles ca 0.2 mm diam., paraphyses few, shorter than sporangia.</p><p>Distribution and ecology</p><p>Southern Colombia, Ecuador and northern Peru (Fig. 2A) at elevations of 150–1400 m a.s.l., in deeply shaded forest on steep rocky slopes.</p><p>Remarks</p><p>The blades of Cyathea werffii vary greatly between being pinnate-pinnatifid to fully bipinnate with slightly oblanceolate, blunt-tipped pinnules with entire to coarsely lobed margins. In the general variation of plant size and blade dissection, it comes close to C. pycnocarpa, with which it also shares comparatively small but abundant petiole scales that may have some darker cells in the white margins. Cyathea pycnocarpa differs in having lanceolate to weakly hastate pinnules (i.e., widest at the base and gradually tapering to an acute tip), the blade is basally truncate with the lowest pinnae patent and barely smaller than the longest pinnae (vs blades obovate-elliptic with the lowest pinnae smaller and reflexed in C. werffii) and the blade apex gradually reduced (vs abruptly reduced). Having seen both species in the field, we can further add that the scaly indument of the axes and veins abaxially tends to be more evident and appear more whitish in C. pycnocarpa than in C. werffii . The laminar texture is thicker and heavier in the former species than in the latter, thus the leaves are arching in C. pycnocarpa and held upright in C. werffii (Fig. 13A), presumably forming a funnel-shape in larger plants.</p><p>The occurrence in Colombia (Cárdenas et al. 2019) is only supported by aberrantly large specimens which look more like plants of C. tortuosa but with bicolorous petiole scales (vs concolorous in C. tortuosa) and notably stalked pinnae (vs mostly sessile or nearly so). These plants could also be a local variant of C. pastazensis, whose small stature with long stalked pinnae may be an adaptation to the very shady locations where they were found.</p><p>The range of C. werffii is sometimes reported to reach southern Peru, but as far as we can confirm, these seem to base on erroneous determinations (also by the first author) of premature plants of other species, like C. pungens and C. tortuosa . We observed Cyathea werffii together with both species at the paratype location in Chiriaco, Bagua, northern Peru (Ellenberg 3489), which allowed us to distinguish between them more clearly (Fig. 13).</p><p>Regarding the general size and shape of the pinnules, the soral line pattern, and composition and color combination of the fine indument, Cyathea werffii is practically identical to C. oblonga from the Guyana highlands, but that species has more numerous and persistent petiole scales that usually reach the lower half of the rachis, only sessile pinnae, and more pinna pairs per leaf (10–12 in C. oblonga vs 4–7 in C. werffii). The similarity may base merely on convergence, but a closer relationship between these two disjunct taxa is also possible, as the Amotape-Huancabamba-zone, where C. werffii is endemic to (Fig. 2A), has many biogeographic ties with the Guayana highlands (Lehnert &amp; Tejedor 2016).</p></div>	https://treatment.plazi.org/id/163C91782827BC1BFDAEBABDF334569E	Public Domain	No known copyright restrictions apply.
