Schltr.</p><p>TYPE SPECIES. — Benthamia latisatis (Thouars) Bytebier (as Benthamia latifolia A.Rich.).</p><p>DISTRIBUTION AND ECOLOGY. — The genus Benthamia is widespread in Madagascar, La Réunion and Mauritius, with possibly one species (probably B. africana (Lindl.) Hermans) on the Comoros (Fig. 3). It ranges from sea level to high altitudes (2600 m). It is generally found in open places, both dry and marshy.</p><p>ETYMOLOGY. — Named for the English botanist George Bentham (1800-1884), who together with Sir Joseph Hooker produced Genera Plantarum (1865-1883).</p><p>DESCRIPTION</p><p>Terrestrial or less commonly epiphytic (5 species) sympodial glabrous herbs with 2-7 swollen generally glabrous tubers, which are in fact tuberous roots. Stem erect or arcuate, sometimes with sheaths only (one species), or with 1-2 radical sheathing leaves, or with 2-10 cauline leaves. Leaves lanceolate, ovate or elliptic, sometimes not developed at anthesis (3 species). Rachis terminal, erect or rarely curved, few- to densely many-flowered. Floral bracts small, usually as long or longer than the ovary. Ovary pedicellate, fusiform or oblong, generally twisted (except Benthamia bosseri). Flowers small, resupinate (except one species with non-resupinate and pendent flowers), arranged in a narrow rachis, white, green or yellow; sepals and petals free or almost free, entire; labellum entire or trilobed; spur cylindrical (nine species) or short and scrotiform, entire or bilobed at apex, or a small hollow only in one species ( B. boiteaui). Column short and massive, subterete, erect; anther erect to slightly deflexed, placed above the rostellum, apiculate or not, bilocular, locules parallel, without anther canals; pollinia two, ellipsoid, granular, 2 caudiculae rudimentary, with two viscidia, detachable, flat, ovate or subelliptic; rostellum small, tridentate or trilobed at the anterior edge; stigma always very short, cushion-shaped, with short convex lobes; auricles two, generally conspicuous, subspathulate or falciform, sometimes lacerated, on lateral sides of column. Fruit a dehiscent capsule, with floral parts persistent on the fruit.</p></div>	https://treatment.plazi.org/id/039B87ABFFD3FFE12222F0C92DFFC6BE	Public Domain	No known copyright restrictions apply.

In La Réunion, several other species have long been included in the species concept, in Madagascar it also encompassed at least three other species, and in Mauritius it is thought to be sympatric with Benthamia spiralis A.Rich. (see the notes under that entry). Even with these clarifications Benthamia africana certainly remains a species complex, and further field observations and DNA analysis may show differences that remained unnoticed in dried specimens. We have kept the holotype as commonly accepted, the only Thouars specimen known of Benthamia africana . However, the illustration given by Thouars (1822, plate 9) shows leaves adpressed on the ground, which is the case for some plants but not all.</p><p>Benthamia procera is included here as a synonym, only the lip midlobe length seems to be the distinctive feature, but the variations of the lip midlobe length on the type itself, from 1 mm to 1.6 mm, which is in the variation range of Benthamia africana, show that it is preferable to consider the type of Benthamia procera as Benthamia africana with an unusually long lip.</p><p>See also: Schlechter (1930: t.12 n°47), Perrier (1939: 31, as Benthamia spiralis A.Rich.), Perrier (1939: 32), Cribb &amp; Hermans (2009: 47, as Benthamia spiralis (Thouars) A.Rich), Bernet (2010: 136, as Benthamia spiralis (Thouars) A.Rich.), Szelengowicz &amp; Tamon (2013: 253, as Benthamia nigrescens Schltr.), Szelengowicz &amp; Tamon (2013: 255, as Benthamia verecunda Schltr.), Hervouet (2018: 157), Pailler &amp; Henze (2020: 72), Hermans &amp; Cribb (2023: 101, except figure 58 p. 105 which is Benthamia mascula Hervouet &amp; Descourv., sp. nov.).</p><p>DESCRIPTION</p><p>Slender terrestrial herb, 20-62 (108) cm tall.Tubers 1-2, ovoid, 20-35 × 4-5 mm, roots fleshy and woolly, up to 65 mm long. Stem cylindrical, 1-5 mm in diameter, with 2 to 3 sheaths. Leaves 3-5, basal or cauline in the lower part of inflorescence, narrowly ligulate or linear-lanceolate, acute, 6-20 × 0.5-2 cm, shortly petiolate, higher on the stem grading into small sheaths. Rachis many-flowered, 6-38 cm long, cylindrical. Floral bracts linear, acuminate 4-12 mm × 0.8-3 mm. Ovary suberect, 4.5-9 × 1-1.9 mm. Flowers very small, 2-5 mm in diameter, secund, spreading, with greenish sepals, green or yellow petals and lip; dorsal sepal cucullate, elliptic, obtuse, 1.8-4.2 × 0.6-1.1 mm; lateral sepals obliquely oblong-ovate, obtuse, 1.8-3.8 × 0.5-1.1 mm, concave at the apex; petals porrect, recurved in apical half, lanceolate, subacute, 1.8-3.8 × 0.5- 1.2 mm; lip trilobed, 1.8-3.1 × 1-2 mm, recurved, lateral lobes 0.2-0.4 mm, obtuse, midlobe fleshy, much longer than the lateral lobes, 0.8-1.3(1.6) mm; spur scrotiform to subrectangular, 0.5-1 to 0.4-0.9 mm across. Column 0.6-1.1 × 0.5-1 mm, auricles short, anther retuse or obtusely apiculate; rostellum trilobed, the three lobes subequal, 0.1-0.2 mm long, obtuse, hardly visible.</p></div>	https://treatment.plazi.org/id/039B87ABFFD3FFEB208FF1A72866C57A	Public Domain	No known copyright restrictions apply.

The species was first described as a sub-species of Benthamia herminioides Schltr. but is readily distinguished by the larger flowers, the fleshy and thick floral parts and the very prominent callus on the lip. Specimens from Mt. Marojejy and Mt. Tsaratanana should be compared when fresh material becomes available from the latter locality.

It can easily be confused with Benthamia rostrata in photographs, though it is a much larger plant. Several Benthamia rostrata specimens have been labelled Benthamia bathieana in the literature and herbaria. Apart from the plant size it differs from Benthamia rostrata by the leaves which are closer together and wider, and its denser inflorescence. The flowers differ from B. rostrata by the petals and sepals twice as long, the side-lobes of the lip which are not equilateral vs equilateral in B. rostrata, the shorter spur, and the paleyellow colour of the flowers (vs. greenish in B. rostrata).</p><p>The gathering H. Perrier 13582 has two sheets in P, but one of them (P00094469) is clearly annotated in Perrier’s handwriting that it is the material that was sent to Schlechter for the description, and can therefore be considered the holotype, with P00094470 being an isotype.</p><p>See also: Schlechter (1930: t.9 n°36), Perrier (1939: 23), Cribb &amp; Hermans (2009: 42, photograph is Benthamia rostrata Schltr).</p><p>DESCRIPTION</p><p>Robust terrestrial herb up to 70 cm tall.

Black sheaths at the base of the plant are common among Benthamia (e.g. B. melanopoda). The lengths of the lateral lobes of the lip compared with the midlobe may vary from 1/3 to about the same length but these variations are visible within the type and syntype of B. verecunda itself.Schlechter did not mention B. elata when describing B. verecunda, though his drawings of both species are very similar. Nor did Perrier mention B. elata when describing B. nigrovaginata . Both compare their species with more obviously different species.</p><p>See also: Schlechter (1930: t.12 n°48), Perrier (1939: 30), Perrier (1939: 33), Perrier (1939: 34), Cribb &amp; Hermans (2009: 46), Cribb &amp; Hermans (2009: 50), Hervouet (2018: 161).</p><p>DESCRIPTION</p><p>Erect terrestrial herb, 25 cm to more than 1 m tall. Tubers 2, oblong or fusiform. Stem 3-7 mm in diameter, with its base enveloped by 2-3 often black sheaths, then carrying leaves in the lower half and higher with 4-6 lanceolate-acuminate sheaths. Leaves 4-6, narrowly ligulate-lanceolate, 10-20 × 1.5-3.5 cm, acuminate, attenuate towards the base. Rachis many-flowered, cylindrical and very long, 20-40 × 1.3 cm, often half of the plant height, rather lax, flowers unilateral or almost so. Floral bracts lanceolate, 1-veined, 4-12 × 1.3-1.5 mm, narrowly acuminate, the lower ones longer than the flower. Ovary slender, cylindrical, twisted, 4.5-11 × 0.8-3 mm. Flowers 3.5-4.5 mm long without the ovary, 3-5.5 mm high, yellow or greenish-yellow; sepals oblong-ligulate, obtuse, 1-veined, 3-4 × 0.6-1.1 mm, the lateral sepals spreading, joined towards the base of the petals and the lip; petals lanceolate-oblong, obtuse, 3.7-5.5 × 0.8-1.4 mm, as long as the sepals, a little attenuate towards the apex; lip oblong, 3.1-6 × 1.2-2.3 mm, concave at the base, trilobed in the upper third, the lateral lobes triangular, 0.5-1.3 mm long, narrowly lanceolate-ligulate, the middle one ligulate-obtuse and 1-3 times larger than the laterals, 1.5-2.3 mm, sub-obtuse, thickened at the apex; spur in a semi-oblong sac shape, very rounded at the apex and a little flattened, 0.6-1.1 × 0.4-0.9 mm. Column subterete, 0.8-1.2 × 0.7-1 mm, anther digitate, slightly deflexed; auricles sub-spathulate, about as long as the anther; rostellum short and trilobed, the lateral lobes small, the midlobe very thick.</p></div>	https://treatment.plazi.org/id/039B87ABFFCDFFFD20FEF76B2F7DC799	Public Domain	No known copyright restrictions apply.

However, examination of a rehydrated flower from the type specimen (Catat 4338) shows no significant difference with flowers from specimens of B. erinacea, it is well within the variation range of B. erinacea .</p><p>The cuspidate leaves of Benthamia cuspidata can be found also in Benthamia nigrescens subsp. humblotiana .</p><p>Perrier gave specimen “ Boivin (sans n°) ” as type of Benthamia nigrescens subsp. borbonica . However there are in P two such specimens L. H. Boivin s.n. bearing his handwriting “ Benthamia nigrescens subsp. borbonica H.Perr. ”, without mention of which one is the type.

This needs to be clarified from fresh material since plants with unusual patterns of leaves often occur in marshy soils (e.g. in Ambondrombe and Itremo).</p><p>Specimen H. Perrier 113 cited by Schlechter in the protologue is an alternative numbering of H. Perrier 11386, which was sent to Schlechter in Berlin and returned, so there is no doubt that this is the holotype.</p><p>See also: Schlechter (1930: t.10 n°39), Perrier (1939: 39, as Benthamia cinnabarina), Cribb &amp; Hermans (2009: 46, as Benthamia cinnabarina, photograph is Benthamia africana), Bosser &amp; Lecoufle (2011: 175, as Benthamia cinnabarina), Hervouet (2018: 163).</p><p>DESCRIPTION</p><p>Erect terrestrial herb, 15-35 cm tall. Tubers many, oblong. Stem 1.5-3 mm in diameter, with 4-5 leaves, basal or up to the middle, a little higher carrying a few sheaths gradually decreasing in size. Leaves, erect, alternate, linear or lanceolate-linear, 6-12 cm × 5-12 mm, acute. Rachis 5-16 cm long, several-flowered, but not very densely flowered, interrupted and spiral. Floral bracts narrow, lanceolate-linear, normally longer than the ovary, 6.5-12 × 1.1-2.5 mm. Ovary 2.5-7.5 × 0.8-2 mm. Flowers small, 4 mm without the ovary; sepals narrowly oblong, obtuse, 3-veined, dorsal sepal 3.5-4.9 × 0.6-1.5 mm, lateral sepals 2.7-4.8 × 0.3-1.2 mm; petals of the same length as sepals, wider, 3-5 × 0.9-1.5 mm, thickened and opaque in the upper half, a little expanded towards the middle of the front edge; lip oblong, 3.6-5.1 × 1.9-3.6 mm, trilobed, in the upper half, the lateral lobes very obtuse and about 2/3rd the size of the midlobe which is wider and around 1.5 mm long; spur scrotiform and a little flattened, as broad as high, 0.8-1.2 × 0.4-1.2 mm. Column 0.7-1.2 × 0.7-1 mm, anther shortly apiculate; auricles broadly spathulate, slightly shorter than the anther; rostellum with two very small lateral lobes and a larger obtuse midlobe, 0.1-0.2 mm long, upwards.</p></div>	https://treatment.plazi.org/id/039B87ABFFF4FFC4222AF78229DAC6BE	Public Domain	No known copyright restrictions apply.

Mainly in Analamanga, Alaotra-Mangoro, Haute Matsiatra and Amoron’i Mania regions, but with one locality in Sava region, Mt. Marojejy. In montane grasslands or marshes from 1000 to 2100 m (Fig. 50). Benthamia herminioides ( subsp. herminioides) and Benthamia herminioides subsp. intermedia were listed as occurring in La Réunion by Szelengowicz &amp; Tamon (2013: 244-245).

They generally have a green calyx and white corolla, but the petals can be also greenish (original subsp. intermedia) or sulphur yellow (Marojejy and Ambondrombe, with plants with white corolla also present). The differences given by Perrier to establish the subspecies intermedia fall within the variability of the species itself, but he noted on the herbarium sheet that the flowers are greenish.</p><p>Perrier also refers to Benthamia herminioides subsp. typica H.Perrier (Perrier 1934: 36) . This name is not validly published (article 24.3 of the International Code of Nomenclature). With subsp. typica Perrier was referring to the autonym name, i.e. subsp. herminioides .</p><p>See also: Schlechter (1930: t.10 n°40), Perrier (1939: 36), Cribb &amp; Hermans (2009: 48), Hervouet (2018: 165).</p><p>DESCRIPTION</p><p>Small or slender terrestrial herb, 20-70 cm tall. Tubers 2-3, 15-25 × 3-4 mm. Stem green, 1.5-3 mm in diameter, with 1-2 tubular sheaths at the base, 15-32 cm × 3 mm, and leaves in the lower half. Leaves 2-3, elliptic-lanceolate or lanceolate, 3-10 × 1.5-2.5 cm, shortly acuminate, very gradually and slightly narrowed towards the base. Rachis 5-25 cm, laxly 15-45 flowered, flowers fairly close together on stem, 3-6 mm apart, unilateral.

It is very variable and very small flowering specimens may appear uncharacteristic. It is perhaps surprising that the species has never been found in Madagascar, where it is replaced by the closely related Benthamia humbertii H.Perrier, with similar flowers but different leaves.</p><p>The Thouars specimen P 00094522 in P is generally considered the holotype of Satyrium latifolium Thouars, however Thouars did not assign types. Therefore, we designate here this specimen as the lectotype, the flower dissection on sheet P 00094523 being an isolectotype.</p><p>See also: Cadet (1989: plate 22, as Benthamia latifoli a (Thouars) A.Rich.), Benke (2004: 64, as Benthamia latifoli a (Thouars) A.Rich.), Bernet (2010: 132, as Benthamia latifoli a (Thouars) A.Rich.), Szelengowicz &amp; Tamon (2013: 244, as Benthamia herminioides ssp. intermedia H.Perrier), Szelengowicz &amp; Tamon (2013: 246, as Benthamia latifolia), Pailler &amp; Henze (2020: 73), Hermans &amp; Cribb (2023: 107).</p><p>DESCRIPTION</p><p>Robust terrestrial herb, 30-180 cm tall.Tubers 2, oblong.Stem cylindrical, 3-10 mm in diameter, bearing two basal sheathing sterile bracts and several lanceolate, acuminate sterile bracts along length.

The flowers are very similar to those of Benthamia flavida but have a smaller lip (lip 2-3.2 mm in Benthamia litoralis sp. nov. vs lip 3.6-5.1 mm in Benthamia flavida), the latter species having very different alternate and erect leaves (vs strap-like and basal in Benthamia litoralis sp. nov.). It is also similar to Benthamia elata, which is a much larger plant (20- 41 cm for Benthamia litoralis sp. nov. vs 25-100 cm for Benthamia elata) with different leaves (linear strap-like for Benthamia litoralis sp. nov. vs ligulate-lanceolate for Benthamia elata), larger flowers and longer rachis (4.5-17 cm for Benthamia litoralis sp. nov. vs 20- 40 cm for Benthamia elata).</p><p>TYPE MATERIAL. — Madagascar • Sava, parc <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=50.416668&amp;materialsCitation.latitude=-15.583333" title="Search Plazi for locations around (long 50.416668/lat -15.583333)">National de Masoala</a>, 1 km au Nord de la rivière Fampotakely; 15°35’S, 50°25’E; 18.IX.1994; G.M.

The flowers are pure white, with a wider trilobed lip. Also similar to Benthamia lakatoensis sp. nov., from which it differs by the shape and position of the floral parts and the flowering time, see the diagnosis of the latter species.</p><p>Perrier distinguished Benthamia nivea subsp. parviflora as follows: flowers smaller (5-6 mm), lateral lobes of lip acute, lip with 3 veins, staminodes (in our study named auricles) half the thickness, rostellum with 3 lobes of equal size. The type is indeed a small plant, but it remains in the variation range observed outside Tsaratanana. Lips with acute lateral lobes are also evident on the type of Benthamia nivea . The number of veins, the auricles and the rostellum are also variable. For all these reasons we prefer to consider Benthamia nivea subsp. parviflora as a synonym of Benthamia nivea .</p><p>The gathering H. Perrier 13507 has three sheets in P and one in K, but H. Perrier’s handwriting on specimen P00094557 clearly shows that it is the sheet sent to Berlin for the description by Schlechter, it can therefore be considered the holotype.</p><p>One specimen, Gautier LG 3656 in G (G00096571), has been added here for reference but with doubts. It has been identified as Benthamia nivea subsp. parviflora by P.J. Cribb but the collector’s notes say “yellow tepals”. A dissection shows no other difference to a small Benthamia nivea .</p><p>See also: Schlechter (1930: t.11 n°44), Perrier (1939: 33), Cribb &amp; Hermans (2009: 50).</p><p>DESCRIPTION</p><p>Erect epiphytic herb, 11-40 cm tall.

Férard et al. 1043; CBNM !.</p><p>NOTES</p><p>After examining the types, we see no significant difference between Benthamia herminioides subsp. angustifolia and Benthamia perfecunda . In his publication of Benthamia perfecunda Perrier only cited Benthamia macra and Benthamia verecunda as similar species. Perrier stated that the leaves of Benthamia herminioides subsp. angustifolia are 5 cm long, this is a mistake since one leaf of the type is 11 cm long, which falls within the Benthamia perfecunda leaf dimensions. The fact that all flowers are pollinated is observed on all specimens and is a strong indication that the plant is autogamous.</p><p>This species is very different from Benthamia herminioides, even though it was initially described as the subspecies angustifolia. Perrier himself says that the stigmas are very different from those of other subspecies of Benthamia herminioides . It is generally a larger plant, with differently shaped leaves (linear to grasslike vs elliptic-lanceolate to lanceolate for Benthamia herminioides). The flowers are fleshy,campanulate,and uniformly green (vs with calyx green and corolla white for Benthamia herminioides). A very distinctive and unique feature in the genus is the 3-ranked rachis (vs secund).</p><p>Changing the rank from subspecies to species was therefore necessary. Then the earliest name at the rank of species has priority (article 11.2 of the International Code of Nomenclature), which is Benthamia perfecunda, B.herminioides subsp. angustifolia becoming a heterotypic synonym.</p><p>Surprisingly this species has long been overlooked in La Réunion, only Bernet illustrated it as Benthamia sp. 4 (Bernet 2010). Jean Bosser consistently noted on his specimens that there were three helicoidal rows of flowers.</p><p>See also: Perrier (1939: 38), Cribb &amp; Hermans (2009: 43), Cribb &amp; Hermans (2009: 48), Bernet (2010: 141, as Benthamia sp. 4), Szelengowicz &amp; Tamon (2013: 245, as Benthamia herminioides subsp. arcuata, photograph on the left only), Hervouet (2018: 171), Szelengowicz &amp; Tamon (2013: 252).</p><p>DESCRIPTION</p><p>Erect terrestrial herb 30-80 cm tall. Tubers 2, roots around 4-6, up to 6 cm long, 1-2 mm in diameter. Stem cylindrical, 2-4 mm in diameter, covered below by blackish sheaths. Leaves 2-4, cauline in the basal half of the stem or slightly higher, 5-15 cm × 5-12 mm, erect, linear or grass-like, acute, amplexicaul at base, with 7-8 veins. 4-5 sterile bracts in the upper half of the stem. Rachis terminal and dense, 6-15 cm long, bearing 20-60 flowers, broadly cylindrical but in fact arranged in 3 slightly spiralling rows, 2-5 mm apart. Floral bracts acicular, 3-10 × 1.1-1.8 mm, slightly smaller than the ovary, rarely a little longer. Ovary elongated, a little arcuatereflexed, green, fusiform, at right angle to the rachis at the end of anthesis, 3-8 × 1-2 mm. Flowers not opening fully, campanulate, 2-3 mm long, nearly aligned with the ovary, green or greenish-yellow; dorsal sepal oblong, 1.5-2.8 × 0.5-1.1 mm, 1-veined; lateral sepals asymmetrically oblong, concave, spreading, 1.5-3.1 × 0.4-1.2 mm; petals broadly oval, 1.2-2.9 × 0.3-2.1 mm, shorter than the lateral sepals, adnate to the dorsal sepal, forming a hood over the lip; lip ovate, trilobed at apex, obtuse, calceolate, fleshy, 1.5-3.2 × 1-3.2 mm, without callus, the lobes reduced to 3 rounded teeth, lateral lobes 0.5 mm long, central lobe equal or longer, blunt, concave in proximal part, lateral lobes folded upwards, up to the petals, so that a rectangular entrance into the flower is formed; spur 0.4-1.5 × 0.2-0.8 mm, horizontal and parallel to the ovary or touching it, obtuse, cylindrical or slightly flattened, not narrowed at the base, straight or curved along the ovary. Column 0.5-1.1 mm high, 0.4-1.2 mm wide, obtuse, anther with an obtuse apiculus; auricles very short, less than a quarter of the length of the anther; rostellum thin, more tri-crenate than trilobed; stigmata distinct, well developed, thick, porrect-claviform, 0.5 mm long.</p></div>	https://treatment.plazi.org/id/039B87ABFFEFFFDB2205F4AB28A4C79A	Public Domain	No known copyright restrictions apply.

Hermans 5219, K !.</p><p>NOTES</p><p>The species can be recognised by its long cylindrical spur and the short auricles. In his original description Schlechter stated that the leaves are not developed at anthesis (“ foliis sub anthesi nondum evolutis ”). This is questionable since all specimens in P have leaves, only one specimen at K has no leaves.</p><p>Schlechter doubted that this species would belong to the genus Benthamia, because of the long spur and the short staminodes (here auricles).</p><p>See also: Schlechter (1930: t.12 n°46), Perrier (1939: 20), Cribb &amp; Hermans (2009: 43).</p><p>DESCRIPTION</p><p>Erect slender terrestrial herb, 10-40 cm tall. Tubers 5-7, stalked, oblong-claviform, downy, roots numerous. Stem 1.5-3 mm in diameter, with 2-3 basal amplexicaul sheaths, 20-35 × 6-10 mm, a tuft of leaves and a few bract-like sheaths higher up. Leaves 5-9, erect, acuminate-aristate, 40-70 × 2-5 mm. Rachis rather dense, bearing 25-45 flowers, elongated, 8-23 cm long, unilateral. Floral bracts lanceolate-linear, 4-7 × 1-1.6 mm, very acute, a little longer than the ovary. Ovary 4-8 × 1-2 mm, a little curved. Flowers small, greenish-brown; sepals elliptic-oblong, obtuse, dorsal sepal 2-2.9 × 0.9-1.3 mm, lateral sepals 2.2-3.1 × 0.9-1.3 mm; petals as long, 2-3 × 0.9-1.4 mm, lanceolate-ligulate obtuse, a little expanded towards the base of the front edge; lip broadly cuneate, 3-4 × 1.6-2.5 mm, trilobed above the middle, lobes not equal, ligulate-obtuse, the middle one thick, around 1.8 mm long, the laterals divergent, around 1 mm long; spur narrowly cylindrical or conical, somewhat obtuse, 2-3 × 0.3-0.8 mm. Anther subglobose; auricles hardly visible at the base of column, suborbicular, twice as short as the anther.</p></div>	https://treatment.plazi.org/id/039B87ABFFE9FFD920CFF668295FC0C7	Public Domain	No known copyright restrictions apply.

Any differences between Benthamia rostrata and B. perularioides do not hold when a large number of specimens are examined. Moreover, there are no distinct distribution zones as suggested by Perrier (Perrier 1939: 24, 25), with Benthamia perularioides north of Ankaratra and Benthamia rostrata south of Ankaratra. This species was also often misidentified as Benthamia bathieana, which added to the confusion.</p><p>Benthamia perularioides and B. rostrata were described in the same publication by Schlechter. The rules of nomenclature allow a choice of which name to prioritise. We have chosen B. rostrata because this name is more widely used. The type indicated by Schlechter for his Platanthera madagascariensis is “Perrier de la Bathie XXI, β“. He copied this on specimen P00094574 which has handwritten XXI and B together with the number 8101. Schlechter (1924: 33) gave “ H. Perrier 8101 (XXI B)” when he coined the name Benthamia rostrata . The specimen P00094574 was thus sent to Berlin and returned to Paris, so there is no ambiguity that it is the holotype. For Benthamia perularioides Schlechter cited Perrier 13523 for the type, but there are in P two specimens with this collection number. We have chosenP00094567 as lectotype because Perrier indicated on it that it was sent to Schlechter in April 1921.</p><p>This species, which has an elongated spur, is different from the type of the genus Benthamia and other species with a scrotiform or short spur. It is perhaps misplaced in Benthamia . As a matter of fact, specimens identified as Benthamia perularioides in (Ngugi et al. 2020) were found to be embedded in Cynorkis .</p><p>At the beginning of the flowering time the spur is enveloped by the bracts, as is also observed in some African Habenaria .</p><p>See also: Schlechter (1930: t.12 n°45, as Benthamia perularioides), Perrier (1939: 24, as Benthamia perularioides), Perrier (1939: 25), Cribb &amp; Hermans (2009: 42, as Benthamia perularioides), Cribb &amp; Hermans (2009: 43), Bosser &amp; Lecoufle (2011: 180), Hervouet (2018: 172).</p><p>DESCRIPTION</p><p>Erect slender terrestrial herb, 22-70 cm tall. Tubers 4-11, clustered, fusiform, slender and white, 5-8 mm in diameter, 20-60 mm long, roots up to 8, wiry, white, 1-2 mm in diameter. Stem 2-4 mm in diameter, with the base covered by sheaths 25-30 mm long, with above slightly fleshy leaves and higher up 7-10 lanceolate sheaths, gradually turning into floral bracts. Leaves 2-3, more or less narrowly oblong, 7-20 × 1.5- 4 cm, shortly acuminate or mucronate. Rachis rigid, erect, 16-25 × 1.2 cm, densely many-flowered, somewhat unilateral with 30-50 flowers. Floral bracts lanceolate, very acuminate, erectly spreading, 5-15 × 1.5-3 mm, embedding the ovary, the lower ones longer than the ovary. Ovary twisted, 5-10 mm long, diameter 0.6-1.6 mm, the basal part fused to the base of the floral bract. Flowers resupinate, c. 7.5 mm and 4 mm deep, olive green turning yellowish; sepals narrowly oblong, obtuse, slightly navicular, the dorsal obscurely 3-veined, erect, 1.8-3.2 × 0.7-1.6 mm, the laterals single-veined, spreading, 2.3-4 × 0.7-1.9 mm; petals narrowly oval-obtuse, obscurely 2-veined, a little expanded at the anterior margin towards the base, 1.7-3.2 × 0.9-1.6 mm, forming a hood with the dorsal sepal; lip a little longer than the sepals, 2.8-4 × 1-2.3 mm, rhomboid in outline, tri-lobed, sometimes geniculate between the spur and the lobes, the central lobe tongue-shaped with apex curving up, obtuse, 1.5 × 0.5 mm, the lateral lobes triangular, obtuse, 0.5 × 0.7 mm; spur subcylindrical, trumpet-shaped at first then becoming thinner, pendent or trapped into the bract, narrowed from the base to the obtuse apex, whitish green, as long as the sepals, 2.3-6 × 0.3-0.6 mm. Anther not apiculate, suborbicular, 1-2.2 × 0.8-1.3 mm, with two distinct chambers; auricles very rounded, thick, almost a quarter the length of the anther; lateral lobes of the rostellum obsolete, the middle one obtuse, pointing backwards. Sweetly scented in the evening.</p></div>	https://treatment.plazi.org/id/039B87ABFFEBFFA720CEF0A42FB8C0C4	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

The latter species appears on page 21 of the same publication under the name Habenaria spiralis (Thouars) A.Rich. Moreover, he wrote on the Néraud 8 type specimen: « non in P. Th. », meaning that it was not a Du Petit-Thouars species. The name was validly published since no one had used the name Benthamia spiralis before. When Schlechter wanted to transfer Benthamia spiralis A.Rich. to Habenaria in 1915, he was hindered by the already existing Habenaria spiralis (Thouars) A.Rich. which has Satyrium spirale Thouars as basionym. He therefore created a new name: Habenaria dissimulata Schltr. Many subsequent authors have mistakenly considered Benthamia spiralis A.Rich as a new name for Satyrium spirale Thouars. To add to the confusion the original Thouars name Satyrium spirale was illegitimate because it was already used by Swartz in 1788, for what is now Spiranthes torta (Thunb.) Garay &amp; H.R.Sweet from Central America. For this reason, Lindley applied the new name Spiranthes africana in 1824, later changed to Benthamia africana (Lindl.) Hermans in 2014. Examination of the types proves them to be different, we have thus Benthamia spiralis A. Rich, endemic to Mauritius, as a different species from Benthamia africana, from Madagascar and the Mascarenes. That Benthamia spiralis A.Rich. was a different species or variety was also the interpretation of Perrier de la Bâthie who wrote (Perrier 1934: 33): « on doit le distinguer comme variété et certains botanistes pourraient même le considérer comme une espèce distincte » (« it must be considered as a distinct variety and some botanists could even consider it as a distinct species »), « avec un port plus robuste et des feuilles plus grandes, plus larges et plus nombreuses » (« with a more robust habit, larger, wider and more numerous leaves »), but he mistakenly named it Benthamia spiralis (Thouars) A.Rich. var. dissimulata (Schltr.) H.Perrier and among other specimens he cited one from La Réunion island (Boivin 1064, P[P00738525]!, which is for us merely Benthamia africana .</p><p>This species differs from Benthamia africana mainly by the more numerous cauline regularly alternate linear leaves, borne up to the base of the rachis, and also by the longer lateral lobes of the lip, the petals with fleshy tips and revolute margins, and the much longer floral bracts, up to twice the length of the ovary. Both plants are growing together and field observations are necessary to know to which extent they hybridize.</p><p>DESCRIPTION</p><p>Erect terrestrial herb 42-66 cm tall. Tubers 2, fusiform, 4 × 0.8 cm, roots 2-6, up to 6 cm long, 1-2 mm in diameter. Stem with the base covered by 1-2 sheaths, 3-5 mm in diameter. Leaves 5-10, erect, linear or strap-like, alternate subdistichous, acute and glabrous, 8-19 cm × 4-11 mm, regularly spaced (internode 2-3 cm), up to the rachis. Rachis terminal (4)7-17(23) cm, bearing 27-45 flowers roughly arranged in a spiral, 4-6 mm apart. Floral bracts linear-lanceolate, acute, enveloping the ovary at the basis, 8-15 mm long, up to twice the length of the ovary. Ovary fusiform, twisted, glabrous, slightly curved at the apex, almost vertical, 5-8 mm long. Flowers resupinate, 2.5-4.5 mm long, green; sepals 1-veined; dorsal sepal elliptic-oblong, 2-3 × 0.8-1 mm; lateral sepals similar or slightly longer, 2.1-3 × 0.9-1 mm; petals oblong-triangular, thickened at the apex, with slightly revolute margins, 2.2-2.6 × 0.8-1.2 mm; lip 2-3 × 1.2 mm, concave in the proximal part, subcanaliculate, clearly trilobed at apex, like a trident, with a thickened midlobe 0.5-1 mm long, obtuse, lateral lobes acute, 0.3-0.5 mm long; spur 0.8-1 mm, slightly bilobed, slightly contracted at the base. Column subterete, 0.5-1 × 0.8-1 mm, with an obtuse to subacute nose-shaped apiculus 0.2-0.3 mm long, with lateral broadly rectangular auricles, with irregular margins; rostellum trilobed, hardly visible in dried material.</p></div>	https://treatment.plazi.org/id/039B87ABFF95FFA520CBF0A62F71C7FB	Public Domain	No known copyright restrictions apply.

Lavergne; photographs .</p><p>NOTES</p><p>Although long overlooked, this species has distinctive features, such as the flat spur, the erect flowers and the leaves similar to those of the local Tylostigma, which shares the same altitude and habitat close to the top of the volcanoes Fournaise and Piton des Neiges. It was noted and briefly described by Bernet (Bernet 2010) who provisionally labelled it Benthamia sp. 3 . It is likely that Jean Bosser also noticed this plant as he systematically noted on his specimens that the lip and petals were green with yellow tips. Another distinctive feature to look for is the erect ovary often prolonged by erect half-closed flowers. It is surprising that among 20 specimens found none were collected before 1969. However, it is unlikely that this is due to a recent arrival, since the plant is endemic to La Réunion. Given the number of very similar specimens and the absence of would-be parents in the same habitat, it is unlikely that this species is a hybrid. In the Benthamia africana complex in Madagascar, some plants (e.g. observation of first author on Sainte-Marie Island) may have two-colour erect flowers with a flattened spur, but in this case all the leaves are basal, as leaves in the drawing by Thouars (Thouars 1822: t.9).</p><p>There is also in the spirit collection in P a sample corresponding to the type P00738518.</p><p>See also: Bernet (2010: 140, as Benthamia sp. 3), Szelengowicz &amp; Tamon (2013: 248, as Benthamia misera).</p><p>DESCRIPTION</p><p>Erect terrestrial herb 25-80 cm tall. Tubers 2-4, fusiform, 2 × 0.8 cm, roots 2-6, up to 7 cm long, 1-3 mm in diameter. Stem cylindrical, 1.2-3 mm in diameter, with leaves in the middle of or slightly lower. Leaves 2-3, 10-15 cm × 5-10 mm, erect, linear, longitudinally folded, rigid. Rachis terminal, 5-15 cm long, bearing 12-24 flowers roughly arranged in a spiral, 4-6 mm apart. Floral bracts lanceolate, acuminate, 8-10 mm long, slightly shorter to longer than the ovary. Ovary fusiform, not twisted, vertical, 5-5.5 mm long, with 3 longitudinal ridges sometimes coloured purple. Flowers not resupinate, hardly opening, 2-3 mm long, all floral parts except lateral sepals forming a loosely closed upward facing tube along the ovary, green with tips of petals, lip and spur yellow; dorsal sepal concave, oval, 2-2.5 × 1.2-1.3 mm; lateral sepals navicular, oblong, spreading, green, 2.8 × 1 mm; petals oblong, shorter than the lateral sepals, 2-2.2 × 0.9-1 mm, forming with the dorsal sepal a hood over the lip, green with a fleshy and yellow apex; lip 2.2-3 × 1.5 mm, without callus, concave in proximal part, trilobed at apex, calceolate, green with yellow apex, with central lobe 0.5-0.6 mm long, thickened, lateral lobes folded upwards, thickened, 0.3 mm long; spur 1 mm, flattened into a disc, not bilobed, slightly narrowed at the base.

However, there is no prominent callus on the lip and the side-lobes of the lip are not as long as the midlobe, which prevented us from putting this species in synonymy with Benthamia melanopoda . It also shares similarities with Benthamia perfecunda . It is surprising that this plant has not been found again on Andringitra since 1924, despite the fact that this area has been visited by many botanists.

Here is a translation of the original Latin description of Benthamia longecalceata by Perrier: “Geophyte, slender, 25-40 cm high, one-leaved. Leaf oval (1.3 × 1-1.5 cm), shortly (5-10 mm) petiolate, acute-acuminate. Inflorescence slender, peduncle a few sheaths. Rachis dense, 2-4 cm long, 7-10 mm wide, 10- to 20-flowered. Floral bracts acute, narrowly lanceolate, shorter than the pedicellate ovary. Sepals one-veined; dorsal sepal obtusely ovate (2 × 1.5 mm), lateral sepals subfalciform (3 × 1.8 mm). Petals obtusely subfalciform, small (2 × 1 mm), one-veined. Lip elongated (2.5 mm), slipper-shaped, spur pendent, cylindric, the same length as the lip (2.5 mm).”</p><p>It is highly likely that Jean Bosser also discovered this synonymy but did not publish it. As a matter of fact, he left several notes on the specimens stating that this species was very close to Hemiperis falcata Cordem. of La Réunion and that further dissections should be done. He even filed the two specimens which were not the holotype in the Cynorkis falcata folder in P, where we found them.</p></div>	https://treatment.plazi.org/id/039B87ABFF99FFAB2208F7282892C57A	Public Domain	No known copyright restrictions apply.
