Branchlets commonly with sparse to dense aculei 1.5–6 mm long (sometimes retrorse, sometimes 2- or 3-fid), or stellate hairs, bristles to 3 mm long, hairs whitish, yellowish or brownish, simple or 2-forked hairs to 2 mm long sometimes present, glandular hairs present in some Australian species or branchlets sometimes glabrous. Stipules ±persistent or sometimes caducous, filiform, linear, subulate to ovate (amplexicaul in S. surattensis; sometimes 2-lobed in S. fallax, 3-lobed in S. elongatifolia), 0.75–15(–20) mm long, 0.3–2.0 mm wide, with fine and sometimes coarse bristles or sometimes glabrous. Leaves alternate, lower leaves usually petiolate, apical leaves sometimes sessile and reduced to linear bracts. Mature leaves: petiole 3–180(– 220 in S. diversifolia, – 240 in S. stewartii) mm long, indumentum similar or dissimilar to that of the branchlet; lamina variable in shape, from simple to 3–7(–9)-lobed even on the same plant (rarely 2- or 4-lobed in S. aspera), (10–) 35–260 mm long, (2–) 25–260 mm wide, cuneate to obtuse at base, entire to serrate or dentate margin, acute to obtuse apex, concolourous or discolourous, lobes when present elliptic to ovate or narrowly triangular, longer than wide, attenuate to obtuse, adaxial surface indumentum of very sparse to dense simple or 1–4-armed hairs, hairs sessile, sometimes with a few aculei, abaxial surface usually with conspicuous foliar nectaries (0.5–15 mm long) at the base of the midrib and sometimes on lateral ribs (sometimes absent in S. brackenridgei, absent in S. fabiana), indumentum of sparse to dense coarse stellate hairs, 1–4-armed, hairs sessile, the indumentum commonly more dense on the abaxial surface, the abaxial surface with midrib and primary vein indumentum usually dissimilar to the interveinal regions, indumentum whitish to yellowish (rarely lamina glabrous). Flowers usually solitary in leaf axils (sometimes paired), appearing to form racemes when upper leaves reduced (e.g. S. diversifolia) or borne in clusters at the tips of branchlets (e.g. S. mustiae); pedunculate, the peduncle (0.5–)1–100(–130) mm long, often elongating in fruit, sometimes greatly so, commonly with coarse bristles and sparse stellate hairs, sometimes glabrous, articulation usually conspicuous; articulated pedicel (rarely absent), 1–15 mm long, with fine to coarse bristles, pedicels sometimes marginally wider distally, indumentum of peduncle and pedicel commonly distinct and diagnostic; epicalyx commonly with coarse bristles and aculei, 5–22-lobed, (1–2 mm long in S. aphela) (5–) 9–37 mm long at anthesis, 0.5–2.5 mm wide, the lobes free or sometimes fused at the base for up to 5 mm, 1- or 3-nerved, linear to subulate (the apex then flattened), entire or distinctly 2-lobed at the apex (the two lobes 0.5–10 mm long), channelled in many species (channelled inside in S. gossypiifolia), commonly appressed to the calyx or spreading to reflexed, with sparse, coarse simple hairs persistent in fruit or glabrous; calyx 5-lobed, 7–35(– 55 in S. gossypiifolia) mm long at anthesis (often enlarged in fruit), lobes ±linear, lanceolate, narrowly triangular, triangular or spathulate, free to the base or sometimes fused for 1–7 mm, 10-ribbed at base, with thickened ribs, the midrib of each sepal being raised and from the receptacle to the notch of each sinus, and continuing along each margin of the sepals (ribs not conspicuous in S. goossensii), indumentum of sparse to dense, simple and stellate, whitish, appressed, erect or apically curved hairs or sometimes glabrous, nectary present or absent, calyx persistent and leathery (or fleshy in S. acetosella and S. gossypiifolia) in fruit; corolla usually large, open and showy (salverform in S. uncinella, funnelform in S. greenwayi), sometimes pendulous; petals obovate, (20–) 35–95 mm long, 15–65 mm wide, white, creamy yellow, yellow or pale to dark pink (deep magenta in S. australensis to purple-red in S. radiata and red in S. uncinella), prominently veined, with a thin red horizontal stripe at the base or a reddish-brown to deep purple petal spot, glabrous adaxially, glabrous or with sparse stellate hairs abaxially or sometimes with fine simple hairs; staminal column shorter than or equal to the petals, straight, (10–) 12–60 mm long, usually the same colour as the petal spot (if present), stamens distributed throughout the column, the filaments 0.5–3.0 mm long, anthers red or yellow; style exserted 1–6 mm beyond apex of staminal column (or rarely included), sparsely hairy (hairs clavate in S. sudanensis), 5-branched, branches 2–12 mm long, stigmas feathery, capitate, wide, the hairs 0.1–0.5 mm long. Capsule 5-celled, loculicidally dehiscent, ovoid to globose, (6–11 in S. scotellii) 12–32 mm long, (6–10 in S. scotellii) 12–23 mm in diameter, shortly beaked, sparse to moderately dense erect or appressed, simple, coarse hairs all over (glandular hairs present in some South American species), glabrescent (or glabrous in S. kirstyae and S. meraukensis). Seeds several per cell, light brown to dark brown, reniform to angular, 2–5 mm long, 2–4 mm wide, sometimes striate, often scaly or variously marked but rarely hairy, with white to cream, light brown or tan funiculus. (n = 18, 36, 54, 72, 90; Skovsted 1944; Menzel and Wilson 1969; Menzel and Hancock 1984; Wilson 1994, 1999; Krapovickas and Fryxell 2004; Lavia and Fernández 2004; Wilson 2006).</p><p>Diagnostic characters</p><p>Sabdariffa is most readily recognised by the prominence of the calyx nervation, where particularly the midrib and margins of each sepal are raised and rib-like (not raised in most other Hibisceae). Most species bear stout simple hairs on a thickened base on the stems and in some cases (e.g. S. diversifolia) the hairs are thickened into prickles. Nectary glands are present on the abaxial surface of the leaf midrib and on the midrib of the sepals in most species. The fruit valves are usually setose and the fruiting calyx is usually leathery (fleshy in S. acetosella (Welw. ex Hiern) M.M.Hanes &amp; R.L.Barrett and S. gossypiifolia). Forked epicalyx lobe apices are diagnostic when present but this character is only found in selected species.</p><p>Distribution</p><p>A genus of 117 species with a primarily tropical distribution, a few species extending to temperate or arid zones. Several species are widely cultivated outside natural ranges for agronomic or horticultural use.</p><p>Etymology</p><p>Fryxell (1988) credits Don (1831) in stating that Sabdariffa is a Turkish name for S. gossypiifolia ( Hibiscus sabdariffa), though this name does not seem to be in current use in Türkiye (Pezen Özdogan et al. 2011). Drury (1858) also concluded that Sabdariffa was a Turkish name and believed H. sabdariffa to have been an early introduction to India by the Mohammedans. As the name is not classically formed, this is interpreted as feminine in accordance with Kosteletzky (1836)</p><p>who combined two species names under this genus with feminine terminations. The name ‘Sabdariffa’ appears in classical literature such as de L’Obel (1576, p. 375) but no explanation or origin is provided for the name in that publication.</p><p>Notes</p><p>De Candolle (1824, p. 449) included nine species in Sect. Furcaria . Kearney (1951, p. 109) stated that Sect. Furcaria was ‘typified by H. furcellatus Desr. ’ However, Fryxell (1988, p. 195) stated that the concept of the section was first restricted to only three species ( Hibiscus surattensis, H. furcatus and H. radiatus) by Kosteletzky (1836, p. 1856) when the section name was raised to generic rank (and thereby taxonomically redefined), excluding H. furcellatus, therefore Fryxell concluded that the first valid selection of a type species was by Borssum Waalkes (1966, p. 57), who designated one of the three species included by Kosteletzky (1836) as the type species. However, the Code does not state that such taxonomic circumscriptions define later choices of type species (Turland et al. 2018), therefore the first known selection, that of Kearney (1951) must stand.</p><p>Don’s (1830) subsection Tuberculatus included a broad range of species, many of which are not closely related or even congeneric under our current concepts. Three of the nine original species belong to our concept of Sabdariffa, therefore we consider one of those species to be a logical choice as the type species of subsection Tuberculatus . We here designate H. diversifolius Jacq. as the type species to fix the application of the name.</p><p>Infrageneric names published with two words (e.g. ‘subsect. Furcaria simplicia ’ and several other infrageneric names published by Ulbrich) are not validly published (see Turland et al. 2018, Art. 21.2, Ex. 2). Hibiscus sect. Furcaria series Friesia Ulbr. (Ulbrich 1921, p. 402) is a synonym of Cravenia McLay &amp; R.L.Barrett (see Hanes et al. 2024).</p></div>	https://treatment.plazi.org/id/03AC0268C365D543FFC6FF349BD0FAD7	Public Domain	No known copyright restrictions apply.

Examination of the formatting in the full publication indicates that this is a deliberate choice of the sheet at LISU as the type and accepted as inadvertent lectotypification. Wilson (1999, p. 68) suggested that the BM specimen would have been more appropriate, as the best set of Welwitsch’s specimens were retained at BM (Hiern 1896) but the choice of Exell &amp; Mendonça (1937) cannot reasonably be overturned. The earlier publication of Hibiscus acetosella Welw. ex Ficalho (de Ficalho 1881) lacked a description and the name was subsequently validated by Hiern (1896).</p><p>Notes</p><p>The commonly cultivated form has red to purple foliage, calyx and corolla. However, the wild-type has green foliage, a red calyx and yellow corolla with a purple centre.

We here designate BM 014117362 as this specimen has a label stating, ‘type’, a copy of the protologue is attached to this sheet and the material is in fertile condition .</p><p>Notes</p><p>The boundaries between Sabdariffa aspera and S. cannabina have been a matter of contention in the literature, especially regarding the placement of synonyms under each name. Fryxell (1990) noted that S. cordofana (Turcz.) Mwachala &amp; R.L.Barrett was likely the same as S. aspera (a view not supported here) and distinct from S. cannabina . Leistner (2008, p. 114) placed H. malangensis Baker f. under S. cannabina but accepted S. aspera . Mwachala (2009) included S. aspera and the associated synonyms under a broad concept of S. cannabina and this has been followed by POWO (see https://powo.science.kew.org/).</p><p>Wilson (1999) considered the presence of a white, woolly tomentum at the base of the calyx to be diagnostic for S. cannabina and absent in S. aspera, a conclusion we support. Van der Burg (2013) also considered the two species to be quite distinct, recognising S. aspera as native to Gabon, whereas S. cannabina is only cultivated there. Van der Burg (2013) states that S. aspera can be further distinguished by leaves with 3–5 lobes, the lobed margins being wavy, and the reddish sepals. Assignment of synonyms is made challenging by the considerable morphological variation expressed in the relevant specimens (especially leaf morphology but also calyx and indumentum characters) and further field-based studies are likely to be required to fully resolve these debates. The synonyms listed above do all appear to conform with van der Burg’s concept of S. aspera in lacking the woolly tomentum on the calyx.</p><p>Wilson (1999, p. 49) notes that several collections examined appear to be natural hybrids between S. aspera and S. cannabina . These specimens should be further investigated for hybridisation possibly resulting from S. cannabina being introduced into the range of S. aspera or whether these may actually represent a discrete taxon with ‘intermediate’ morphology.</p><p>We here consider Wilson’s (1999, p. 68) concept of S. aspera to apply mostly to S. cordofana and S. verrucosa, and only partially to the type concept of S. aspera . Although the delimitation of S. aspera, S. cordofana and S. verrucosa will require further study by local workers, we here distinguish S. aspera from these other two species based on whether the epicalyx lobes are ±flat when dry ( S. aspera) or have distinct marginal ribs ( S. cordofana and S. verrucosa). The typical form of S. aspera appears to have epicalyx lobes that are almost as long as the calyx lobes at anthesis (v. ~1/2 the length in related taxa). We also tentatively list synonyms under S. aspera based on the same character states, noting that several of these may well warrant recognition as discrete taxa but resolution of these matters is beyond the scope of the current study. We note as an example that specimens at P identified as Hibiscus asper (as at April 2024) are a mix of S. aspera, S. cannabina, S. cordofana and S. verrucosa, with occasional specimens of other species including S. elongatifolia (Hochr.) Mwachala &amp; R.L.Barrett. We have included Hibiscus malangensis and H. vanderystii De Willd. in the key to African species below under those names to encourage further study of these poorly known taxa.</p><p>M.Pobegun 1032 from Guinae (P 06721267) notably has deeply lobed lower leaves and simple, almost linear leaves subtending the flowers. A specimen from the Democratic Republic of The Congo (J.Koechlin JK3715; P 06721279) also has simple leaves subtending the flowers.</p><p>Specimens from Madagascar previously assigned to S. aspera (e.g. P.B.Phillipson et al. 3890; MO, P 00554877) may represent a distinct new species endemic to Madagascar.</p><p>Future studies should investigate consistency of the calyx length relative to the ovary length at anthesis, calyx indumentum (including glands and aculei), corolla colour and relative variation in leaf lobing at different growth stages (e.g. basal v. climax leaves) including lobe margins).</p><p>Distribution</p><p>Based on examination of specimens at P, S. aspera as defined here occurs in Cameroon, Côte d’Ivoire, Guinae, Liberia, Mali, Mauritania, Niger, Senegal, Sierra Leone and possibly extends south as far as Angola.</p></div>	https://treatment.plazi.org/id/03AC0268C368D54FFC82FDCB9F8AFC95	Public Domain	No known copyright restrictions apply.

(2024, fig.).</p><p>Typification</p><p>Linnaeus (1759) is not known to have examined a specimen of this widely cultivated species and rather appears to have relied entirely on early literature, hence Wijnands (1983, p. 144) designated an illustration in Commelin (1697) as the ‘lectotype’ of this name (that is to be corrected to neotype as the illustration was not explicitly cited by Linneaus). Whereas the choice is entirely consistent with the protologue and in our opinion entirely appropriate, the neotypification has left lingering doubts about the application of the name, especially as the diagnostic woolly tomentum on the calyx is not evident in this figure. Wijnands (1983, p. 144) suggests that the woolly tomentum is represented by white patches on a coloured original of the figure, however we have now examined images of S. radiata from eastern India with white stripes on the calyx that better match this representation.</p><p>We are now convinced that the plant illustrated represents our concept of Sabdariffa radiata, based on the appearance of the stem aculei, the distinct aculei on the leaf petioles, the upper leaves being deeply divided (not simple), the shape of the leaf margins and the white but not woolly calyx. The floral features are ambiguous as presented, especially the representation of the epicalyx, matching neither S radiata nor S. cannabina as we define these, and most likely represent artistic licence (or the forks on the epicalyx may have been entirely overlooked). Although there is extensive historical confusion between the two taxa, we consider the application of this name to the taxon here recognised as S. radiata to be too disruptive, therefore we are preparing a proposal to conserve the name Hibiscus cannabinus with a conserved type to maintain current usage of both names.</p><p>There is confusion in the literature regarding the application of the name Hibiscus tripartitus, as different authors either ascribe this to Sabdariffa cannabina (e.g. Wilson 2006; POWO, see https://powo.science.kew.org/) or Fioria vitifolia (L.) Mattei (e.g. El-Hadidi et al. 1999). Forsskål and Niebuhr (1775) cite no specimens and do not refer to any prior literature references, therefore the name is assumed to be based entirely on Forsskål’s own collections (see Hepper and Friis 1994, p. 197). We have only located a single specimen referable to this name, meaning that this is potentially the holotype though further duplicates may be extant. The specimen is in mature fruit, consistent with the protologue and fits the current concept of S. cannabina sens. lat., though this complex requires further review.</p><p>Howard and Howard (1911) did not list any specimens for their new varieties in Hibiscus cannabinus and as such the only unambiguous original material we can identify at this stage constitutes the plates published with the protologues. Borssum Waalkes (1966, p. 64) notes that a number of the Howard and Howard (1911) varieties were cultivated at Bogor, with specimens held at BO and L, therefore these may serve as epitypes if the illustrations are insufficient for identification. Wilson (1999, p. 65) considered the varietal names of Howard and Howard (1911) to be cultivar names. However, Howard and Howard (1911, p. 16) state that there are ‘five varieties comprising eight agricultural types’, demonstrating that the varieties were considered to be more than agricultural selections and the names are here considered to fall under the International code of nomenclature for algae, fungi and plants (Turland et al. 2018) rather than the International code of nomenclature for cultivated plants (see https://www.ishs.org/scripta-horticulturae/internationalcode-nomenclature-cultivated-plants-ninth-edition).</p><p>Notes</p><p>Whether Hibiscus tripartitus, described by Forsskål and Niebuhr (1775), is actually a synonym of S. cannabina is questionalble and the affinity to S. verrucosa should also be considered.</p><p>Schumacher and Thonner (in Schumacher 1827) described two additional species from Ghana, H. congener and H. obtusatus but these are considered to be potentially wild forms of this widely cultivated species.</p><p>We were unable to locate a type specimen for Hibiscus cannabinus var. sudanicus therefore this name is only tentatively placed here. Wilson (1999, p. 49) examined material at G and P, and considered the type specimens to represent a hybrid between S. cannabina and S. acetosella .</p><p>Hibiscus cannabinus var. simplex was recognised by Hauman (1963, pp. 109–110), including var. viridis as a synonym.</p><p>We were unable to locate a type specimen for Hibiscus henriquesii (Pires de Lima 1921), therefore application of this name requires confirmation, though the description and type location are consistent with the placement here .</p><p>Distribution</p><p>Native to Africa and Arabia, in Angola, Bénin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of The Congo, Eritrea, Ethiopia, The Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Kenya, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Swaziland, Tanzania, Togo, Uganda, Yemen, Zambia and Zimbabwe.</p><p>Introduced and commonly naturalised to Afghanistan, Bangladesh, SE Brazil, Cape Verde, China, Cuba, Dominican Republic, Guatemala, Haiti, Honduras, Hungary, India, Iran, Iraq, Jamaica, Kazakhstan, Kriti, Laos, Leeward Islands, Nepal, Niue, Pakistan, Perú, Puerto Rico, Russia, Sri Lanka, Thailand, Trinidad and Tobago, Turkmenistan, Ukraine, Uzbekistan, Venezuela, Vietnam and the Windward Islands.</p></div>	https://treatment.plazi.org/id/03AC0268C357D575FFD2FE3E9B82FB02	Public Domain	No known copyright restrictions apply.

Application of the name Hibiscus tripartitus Forssk. (currently considered a synonym of S. cannabina) should also be considered in this regard as this might lack a woolly tomentum on the calyx, though the maturity of the type (in fruit) makes this difficult to assess. If H. tripartitus is found to be the same as S. cordofana, H. tripartitus would have priority but on current evidence we retain H. tripartitus under S. cannabina .</p><p>Sabdariffa cordofana is allied to S. verrucosa in having epicalyx lobes with distinct marginal ribs when dry but appears to differ consistently from S. verrucosa with climax leaves that are 3–5-lobed for at least half the length ( v. variously entire, shallowly lobed or possibly deeply lobed when the plants mature), small ( v. large), scattered aculei on the stems, and the epicalyx and calyx glabrous except for large, prominent aculei on the margins ( v. epicalyx and calyx with a few stiff hairs and long, very prominent aculeli on margins and ribs).</p><p>Some specimens from Sudan (e.g. H.Gillett 77; P 00925200) and Cameroon (e.g. E. de Garine EG925; P 01080937) approach S. aspera in having deeply divided climax leaves but differ markedly in the calyx characters and our present concepts likely still represent an oversimplification of variation in this species complex across tropical Africa</p><p>Distribution</p><p>Known to occur in Ethiopia, Sudan and Chad. Probably more widespread in East Africa to northern Cameroon but a critical examination of specimens currently assigned to S. aspera and S. cannabina is required to determine the full distribution.</p></div>	https://treatment.plazi.org/id/03AC0268C352D576FCD5FCE59DF5FEE7	Public Domain	No known copyright restrictions apply.

In this case, two collections were clearly cited in the protologue of Hibiscus cuanzensis, both assigned the species number ‘Welwitsch 5241’. However, Exell and Mendonça (in Exell 1936, p. 136) were explicit that the collection from ‘near Cazella’ was the ‘Typus in Herb. Mus. Bot .’ and as there is only a single collection at BM matching these details, we accept this as a holotype despite the existence of uncited isotypes. This was also the conclusion of Exell and Mendonça (1937, p. 167) and Wilson (1999, p. 71). Two collections with a derived label ‘Distr. Pungo Andongo’ are likely isotypes but given the aggregation of collections by Welwitsch, we cannot be certain of this. Four specimens simply labelled ‘ Iter Angolense’ cannot be reliably assigned to a location, therefore these are listed above as possible isotypes. The specimens from ‘Calunda Mangue’, while constituting original material, are not type specimens.</p><p>Distribution</p><p>Cuanza Norte, Angola.</p></div>	https://treatment.plazi.org/id/03AC0268C35CD579FF28FD489F29F867	Public Domain	No known copyright restrictions apply.

We refrain from designating a new neotype pending further study and investigation as to whether original material may be extant. This species has also become popular in local horticulture in eastern Australia, therefore proposing a conserved type that maintains the current usage of the name may be advisable, despite the historical nomenclatural confusion dating back at least to Bentham (1863).</p><p>For Hibiscus magnificus F.Muell., we refrain from designating a lectotype pending further study. Mueller described flowers but none are present on the two sheets remaining at MEL. A sheet at K from Burdekin is highly likely to be original material and the source of the floral descriptions but that location is not cited in the protologue. Additional syntypes may possibly be present at K that may be more appropriate choices as a lectotype .</p><p>There is no material at MEL annotated with the name Hibiscus heterophyllus var. flaviflorus, however there are four sheets annotated by Mueller as varieties, one as ‘var. hypoglauca’ (MEL 2222514) and three as ‘var. lutea’. We conclude that Mueller (1868, p. 170) changed the epithet from ‘lutea’ to ‘flaviforae’, given that the meaning is essentially the same and recognise the three relevant sheets as syntypes of Hibiscus heterophyllus var. flaviflorus . We here choose the only specimen with flowers present as lectotype of this name. We also note that Hochreutiner (1900, p. 99) later validated Mueller’s original variety name Hibiscus divaricatus var. luteus but the two names are treated entirely independently, in part because the identification ‘ Hibiscus radiatus var. luteus ’ is only annotated on a specimen collected after the publication of Mueller’s epithet ‘flaviflorae’.</p><p>There is another collection of Hibiscus divaricatus var. luteus at MEL (Rockhampton, 2 Jan. 1876, P. A.O’Shanesy 1580, MEL 0046761!) that was considered as a possible syntype but the date on the label differs and the collections are not morphologically congruent, therefore we do not consider the MEL sheet to be original material and no duplicate material appears to have been retained at MEL.</p><p>Notes</p><p>A number of synonyms listed above were previously considered to be yellow-flowered forms of S. heterophylla but we prefer to place these under S. divaricata pending further study of this species complex.</p><p>Distribution</p><p>Queensland and New South Wales, Australia .</p></div>	https://treatment.plazi.org/id/03AC0268C35CD57BFCC1F97E9B7AFC51	Public Domain	No known copyright restrictions apply.

The origins and native range are commonly accepted as African, occurring in Angola, Botswana, Burkina Faso, Burundi, Cameroon, Chad, Congo, Democratic Republic of The Congo, Egypt, Ethiopia, Gabon, Guinea, Kenya, Liberia, Madagascar, Malawi, Mozambique, Niger, Rwanda, Senegal, South Africa, Sudan, Tanzania, Uganda and Zambia.</p><p>POWO (see https://powo.science.kew.org/) considers this subspecies to be introduced in many other regions of the world but we accept this as also native to Asia, Australia, Brazil, the Cook Islands, Costa Rica, Fiji, Galápagos, Mauritius, Mexican Pacific Islands, Mexico, New Caledonia, New Guinea, New Zealand (North Island), Niue, the Philippines, Saint Helena, Tubuai Islands and Vanuatu.</p><p>Several lines of evidence support the natural occurrence of S. diversifolia subsp. diversifolia, especially in the Pacific. A primary argument is that the Hawaiian S. brackenridgei is purported to be derived from S. diversifolia (Wilson 1993) and S. brackenridgei is placed as sister to S. diversifolia in our phylogeny (Fig. 6), albeit with very limited sampling. Sabdariffa brackenridgei is clearly in the ‘African’ clade, indicating dispersal at some point. If S. diversifolia is the ancestral origin of S. brackenridgei that has clearly diverged significantly in morphology since arriving in Hawai’i, there was likely a source population of S. diversifolia (or a progenitor) somewhere around the Pacific early enough for dispersal and divergence to occur. The French Polynesian species Sabdariffa australensis is likely to also have been derived from S. diversifolia and the affinity of S. kitaibelifolia should also be investigated.</p><p>Specific evidence for the natural occurrence of S. diversifolia in the Pacific comes from fossil pollen discovered in the Galápagos that significantly pre-dates human arrival in these islands ( van Leeuwen et al. 2008). Fossil Hibiscus - type pollen is also known from pre-settlement deposits in New Zealand, though this may represent S. diversifolia or Hibiscus trionum (sens. lat.) (Newnham and Lowe 1991; de Lange et al. 2018). We conclude that this is a native species in most countries and islands listed as introduced locations by POWO (see https://powo.science.kew.org/) but some of these, especially Mexico and Brazil, may require more detailed studies to assess the status as a native or adventive species. This species is suggested to be an introduction on Norfolk Island by Polynesian settlers (MacPhail et al. 2001) but even that remains uncertain and a global review is justified. This species is listed for Hawai’i (USA) but is considered to be only in cultivation there.</p></div>	https://treatment.plazi.org/id/03AC0268C35FD57AFFD8FC7E9B58F882	Public Domain	No known copyright restrictions apply.

Coutinho et al. (2025) adopted a different view, accepting only the original parchment versions as original material and designated a replacement lectotype. The original artwork for this figure can be viewed through the website of the Biblioteca Nacional do Rio de Janeiro (http://bndigital. bn.br/acervodigital; see also Knapp et al. 2015 and Coutinho et al. 2025).</p><p>Although Mwachala (2009) cited the holotype of Hibiscus rivularis as being at BM, Bremekamp and Obermeyer (1935) explicitly stated that the type was held at PRE. As there are two sheets at PRE, Coutinho et al. (2025) designated PRE 0457138-0 as the lectotype based on the quality of the material on the sheet.</p><p>Notes</p><p>Exell (1961, p. 444) reduced Hibiscus rivularis Bremek. &amp; Oberm. to a subspecies of H. diversifolius . However, the name Hibiscus agioxillos Vell. has priority but the application of Vellozo’s name was uncertain when H. rivularis was named by Bremekamp &amp; Obermeyer (1935) and also when recombined by Exell (1961), therefore the priority was not recognised. We here agree with Krapovickas and Fryxell (2004, pp. 66–67) that H. agioxillos can reliably be applied to the taxon most commonly known as Hibiscus diversifolius subsp. rivularis (Bremek. &amp; Oberm.) Exell.

This species has bifurcate epicalyx lobes, linear to subulate stipules, peduncles &lt;5 cm long in fruit and stems that are relatively finely aculeate or aculeolate.</p><p>Pradeep and Sivarajan (1991, p. 635) simply state that ‘Willdenow’s name pertains to a very different species as observed by Paul and Nayar (1980, p. 195, 1988, p. 123).’ Paul and Nayar (1980, p. 195) similarly simply state that H. furcatus and H. hispidissimus are distinct entities, without defining the application of H. furcatus Willd. This discussion is largely repeated by Paul and Nayar (1988, p. 123) under H. aculeatus but again, application of H. furcatus Willd. is not addressed. In the key to species in Paul and Nayar (1988) and Paul (1993), the specimen in question would key to S. hispidissima but is clearly a distinct species.</p><p>Willdenow (1809, p. 736) places a question mark after the cited location ‘ India orientali? ’, indicating doubt over the origin of the material cultivated in Berlin. There is commonly confusion between ‘East India’ and ‘East Indies’ (Indonesia) but the specimen does not readily match any Malesian species either (see Borssum Waalkes 1966).</p><p>Wilson (1999, p. 49) states that H. furcatus Willd. ‘occurs in India and Thailand’. Indeed, this name was used in a review of Thai Hibiscus (Phuphathanaphong et al. 1989, pp. 49, 54, fig. 4), however the application was confused there, with H. furcatus Roxb. and H. aculeatus Roxb. included as synonyms and the plant illustrated is S. hispidissima .</p><p>Wilson (1999, pp. 56–57) provides the only description that applies to the type concept, considering this a rare species in India and Thailand, citing a small number of collections. While confusion abounds in the literature and in names applied to specimens in herbaria, we here accept that Wilson’s (1999) concept as the type of H. furcatus Willd. does not match any other species.</p><p>Photographs that can be matched to the type collection have recently been identified on iNaturalist (observation numbers: 28993434; 64936961; 92749419; 149528955) therefore we can now record the species for Maharashtra, Karnataka and Madhya Pradesh in India . Observations had previously been assigned to S. hispidissima, sometimes with doubt as this has a shrubby habit, quite distinct from the scrambling or climbing habit of S. hispidissima .</p><p>Distribution</p><p>Maharashtra, Karnataka and Madhya Pradesh, India and possibly also in Thailand .</p></div>	https://treatment.plazi.org/id/03AC0268C35BD57EFF14FAE49A1BF9A3	Public Domain	No known copyright restrictions apply.

The original artwork for this figure has been designated as lectotype of the name by Coutinho et al. (2025) and can be viewed through the website of the Biblioteca Nacional (http:// bndigital.bn.br/acervodigital; see also Knapp et al. 2015).</p><p>Acevedo-Rodríguez (2005) discusses the work of Augustín Stahl in illustrating the flora of Pueto Rico. Acevedo-Rodríguez (2007) formally designated a lectotype for Hibiscus tomentosus A.Stahl based on an original watercolour by Stahl.</p><p>We here designate G 00381130 [mounted on 2 sheets] as the lectotype of H. dominicus as this has an original determination as ‘ Hibiscus dominicus sp. nov. ’ by Hochreutiner and the material is from Chodat’s herbarium (see Chodat and Hassler 1905).</p><p>Notes</p><p>Hibiscus furcellatus var. azuensis (Urban and Helwig 1928, p. 236) was accepted by Acevedo-Rodríguez and Strong (2012) based on a passing reference in Liogier (1981, p. 93) but Liogier (1981) noted that the variety has only been described, not accepted.

Jacek Wajer (BM; pers. comm.) has confirmed that there is no known extant specimen that can be associated with Miller’s description, neither in the main collection of BM nor the Sloane collection, Linnean Society collection or Clifford Herbarium. No illustration can be directly linked to this name and, although Miller cites a polynomial from Tournefort, there is no illustration associated with that polynomial. Although Miller may have observed the species in cultivation in the Apothecaries’ Garden at Chelsea and not preserved a specimen, the source of his description was likely earlier works (e.g. Hughes’s The Natural History of Barbados; Sloane’s Voyage to Jamaica and Natural History of Jamaica and in Browne’s The Civil and Natural History of Jamaica), explaining his presumption that this was a New World species, distinct from ‘true’ roselle from the Old World (Jacek Wajer, pers. comm.). Wester (1911, p. 96) points to Sloane (1707) as the first to record use of the fruit for food in Jamaica and this would seem to be a fairly direct link to Miller’s concept of his species (Miller 1768).</p><p>Abedin (1979, p. 10) used the name Hibiscus gossypiifolius for the taxon traditionally called H. sabdariffa (which Abedin applied to H. cannabinus) and cited ‘ Holotype: (BM)’ but as this cannot actually be linked to any specimen (as noted above), the statement does not qualify as an inadvertent neotypification.</p><p>As no original material can be traced, a neotype must be selected for Miller’s name. We here select a modern collection with a known cytotype to fix the application of Miller’s name to the cultivated form of roselle with large, fleshy, red calyces consistent with the typification of Hibiscus sabdariffa L. by Fryxell (2001 b). We choose a cultivated specimen originating from Cuba over any material from Jamaica as the selected neotype has a known chromosome number of 2 n = 72. Given the long utilisation of this species and known variation in chromosome number, future workers may wish to formally recognise different cytotypes as distinct taxonomic entities and in such a case, an epitype will subsequently not be required to fix the application of this name.</p><p>We here select the cited illustration as lectotype of the name Hibiscus digitatus var. kerrianus DC. as we have not been able to trace any other original material, though a Bonpland collection may possibly be extant somewhere.</p><p>Howard and Howard (1911) did not list any specimens for the new varieties under Hibiscus sabdariffa and as such the only unambiguous original material we can identify is here considered to be the plates published with the protologues that are simply recognised as ‘type’ here, in case actual specimens can be located that might more appropriately serve as lectotypes. Wilson (1999, p. 65) considered the varietal names of Howard and Howard (1911) to be cultivar names. Howard and Howard (1911, p. 32) state that ‘Four different forms in all have been isolated by us and these have bred true. As the differences are very distinct and of a morphological nature rather than agricultural, we have formed the following four varieties:’, demonstrating that the varieties were considered to be more than agricultural selections and the names are here considered to fall under the International code of nomenclature for algae, fungi, and plants (Turland et al. 2018), rather than the International code of nomenclature for cultivated plants (see https://www. ishs.org/scripta-horticulturae/international-code-nomenclaturecultivated-plants-ninth-edition).</p><p>Notes</p><p>Bertoloni is commonly considered to have first published 60 new names in his Florula guatimalensis (Bertoloni 1840), a reprint from work published earlier in 1840 in Novi Commentarii Academiae Scientiarum Instituto Bononiensis, including the illegitimate Hibiscus cruentus Bertol. However, Baldini et al. (2019) present a comprehensive review of these names and the associated types, correcting the place of first publication to Bertoloni in Alessandrini (1840) and identifying authentic type material.</p><p>Wilson (1999, p. 65) considered the varietal name ‘Altissima’ of Wester (1914) to be a cultivar name and we agree with this conclusion. We list the name here as this is sometimes treated as a variety under the ICN (Turland et al. 2018) in the literature (e.g. Rakshit and Kundu 1970).</p><p>Distribution</p><p>As this species has a long history of cultivation, the precise native range is difficult to define. Sabdariffa gossypiifolia is generally considered native to the Central African Republic, Chad, Democratic Republic of The Congo, Gabon, Ghana, Nigeria and Sudan.</p><p>Introduced and commonly naturalised in the Andaman Islands, Angola, Australia, Bangladesh, Belize, Bénin, SE Brazil, Burkina Faso, Cambodia, Cameroon, Caroline Islands, Cayman Islands, China, Colombia, Comoros, Cuba, Dominican Republic, Egypt, El Salvador, Fiji, The Gambia, Guatemala, Guinea, Guinea-Bissau, Gulf of Guinea Islands, Haiti, India, Iraq, Jamaica, Laos, Leeward Islands, Madagascar, Malawi, Mali, Marianas, Mauritania, Mauritius, Mexico, Mozambique, Namibia, Nepal, Niger, Pakistan, Perú, Puerto Rico, Réunion, Senegal, Sierra Leone, Solomon Islands, Somalia, South Africa, Sri Lanka, Taiwan, Tanzania, Thailand, Togo, Trinidad and Tobago, Vanuatu, Venezuela, Vietnam, Windward Islands, Zambia and Zimbabwe.</p></div>	https://treatment.plazi.org/id/03AC0268C346D564FCECF98E9A78FDE7	Public Domain	No known copyright restrictions apply.

(G 00218926); India: Wallich Cat . 2692 (K 001116821, K 001116822); cultivated from seed from New South Wales [Australia] (BR 0000013466190; BR 0000013466206). Wilson (1999, p. 77) states that Roxburgh’s illustration [Icones Roxburghianae 1506 (K)] is of the white-flowered form of S. heterophylla from Australia. Roxburgh (1832) does not mention the name but does list Hibiscus heterophyllus as a species from New South Wales, cultivated in the botanic garden (represented by BM 013732147), consistent with Wilson’s interpretation.</p><p>We here exclude all the yellow-flowered forms from the concept of S. heterophylla, placing these under S. divaricata instead, but further research on this complex is required.</p><p>Distribution</p><p>Queensland and New South Wales, Australia .</p></div>	https://treatment.plazi.org/id/03AC0268C343D569FF10FC049C2AFDAC	Public Domain	No known copyright restrictions apply.

A problem has been identified here in that Furcaria roxburghii Kostel. is a validly published replacement name for the greatly confused Hibiscus furcatus Roxb. ex DC. This appears to be the earliest name available at species rank for this taxon. The name was presumably overlooked as a valid name as the generic combination Furcaria proposed by Kosteletzky (1836) was an illegitimate homonym, but this does not invalidate the species combination as there was a valid genus Furcaria (Desvaux 1827) . However, we refrain from adopting this epithet due to the great confusion surrounding Roxburgh’s concept of ‘ Hibiscus furcatus ’, and we propose conservation of the name Hibiscus hispidissimus Griff. as a more stable nomenclatural solution.</p><p>Distribution</p><p>Native to Bangladesh, Cambodia, China, India, Myanmar, Sri Lanka, Thailand and Vietnam.</p><p>Introduced in Sudan and possibly introduced in Nepal.</p></div>	https://treatment.plazi.org/id/03AC0268C34CD569FF3DF9E39BF7F95A	Public Domain	No known copyright restrictions apply.

Hillier (1907, p. 338) assigned the name to ‘ Hibiscus radiatus, Sims, not of Benth., doubtfully of Cav.’ based on specimens received at K in April 1907, directly linked to de Perini’s fibre plant. These specimens have not been traced but are likely to be extant at K. Careful examination of the figures included with the protologue suggests that calyx glands are absent, and the leaf lobes are also arranged on one side of the petiole (i.e. spanning ≤180°) and prominently toothed, all characters consistent with S. radiata, therefore we agree with inclusion under this species. A postscript by J. Knight notes that the ‘botanical details’ originally provided in manuscript form were omitted from the final publication (de Perini 1905, [p. 14]) and this has not assisted taxonomic determination of the entity described. De Pereni’s plant is likely identical to the earlier described Hibiscus unidens, also named from material sourced in Brazil.</p><p>Distribution</p><p>Considered native to India and Myanmar.</p><p>Commonly cultivated and often naturalised in NE Argentina, Bangladesh, SE Brazil, Central African Republic, Colombia, Cuba, Dominican Republic, El Salvador, Galápagos (Ecuador), Honduras, Laos, Leeward Islands, Mexico, Paraguay, Puerto Rico, Thailand, Trinidad and Tobago, southern USA, Venezuela and the Windward Islands.</p></div>	https://treatment.plazi.org/id/03AC0268C332D517FFD3FEF19A83FC09	Public Domain	No known copyright restrictions apply.

Confusion may have arisen as there is a collection of S. maculata by Ekman (P 04698652) from the type location of S. scabricaulis and the assumption may have been made that there would be only one species at this location. The general indumentum and leaf shape in S. scabricaulis are more similar to those in S. costata, though do not appear to directly match that taxon either. Occasionally misspelt in the literature as ‘ scabriusculis ’.</p><p>We have been unable to match the type to any described species and hence choose to recognise this as a distinct taxon at specific rank. This species differs from S. furcellata in stem and calyx indumentum (short stellate hairs with large aculei) and the epicalyx lobes only very slightly bifurcating (commonly appearing simple), similar to S. maculata .</p><p>Distribution</p><p>Massif de la Hotte, Haiti.</p></div>	https://treatment.plazi.org/id/03AC0268C33DD51BFCE0F92C9A06F862	Public Domain	No known copyright restrictions apply.

Type citation: ‘Crescit in sabulosis humidis insule fluminis Senegal dictae Sorr, prope Saint-Louis.

(lecto, here designated: P 06721189).</p><p>Descriptions and illustrations</p><p>Guillemin et al. (1831, p. 57); Wilson (1999, p. 68, fig. 2c, in part, as H. asper).</p><p>Typification</p><p>No authentic material of Hibiscus verrucosus has previously been identified. Mwachala (2009, p. 41) cited a collection by A.Petit at P as a possible holotype but this may not be original material. There may be original material of H. verrucosus in the Gay Herbarium, collected in Senegal prior to the description of H. verrucosus and used in preparation of the Flora Senegambiae Tentamen (see Gillett 1962) but collection details on specimens examined to date in the Gay Herbarium do not match the protologue. A sheet at BM may be original material: Senegal, Feb. 1825, Perrottet 55 (BM 013730377) but this requires confirmation. Searching of digitised collections at P, however, has identified material matching the protologue location and month of collection, and bearing the name Hibiscus verrucosus . Leprieur is also mentioned as a collector in the preface to Guillemin et al. (1831). This specimen (P 06721189) is here designated as lectotype of H. verrucosus as we consider the possibility for any other potential original material to be unequivocally linked to the protologue unlikely, and we consider the fixation of the application of this name with a lectotype to be highly desirable.</p><p>Notes</p><p>Hochreutiner (1900) and many other authors have treated S. verrucosa as a synonym of S. cannabina but usually without knowledge of the type material of S. verrucosa . Wilson (1999) suggested that this may well be an earlier name for S. aspera . Location of original material allows these competing ideas to be critically assessed.</p><p>Collections from Richard Toll, Senegal (J.G. Adams 11112; P 02143634) and Auwie, Senegal (J.Trochain 1067; P 06721038) appear to be a good match for the lectotype of S. verrucosa, bearing entire leaves. Another collection from Richard Toll, of significance for understanding variation in this species, has very deeply divided leaves, therefore the entire leaves on the lectotype may reflect young or rapid growth. Specimens from Guinea and Mali with a combination of entire and 3-lobed leaves also fit with our concept of S. verrucosa (e.g. J.G.Adams 11699; P 02143597).</p><p>Wilson’s (1999, p. 68) concept of S. aspera includes our concepts of both S. cordofana and S. verrucosa, and our concept of S. aspera . Although the delimitation of taxa in this complex will require further study by local workers, we here distinguish two groups of species based on whether the epicalyx lobes are ±flat (when dried, somewhat fleshy-thickened when fresh) with stiff hispid hairs only ( S. aspera) or have distinct marginal ribs and prominent aculei ( S. cordofana and S. verrucosa). We recognise S. cordofana from East Africa as a related but disjunct taxon relative to our West African concept of S. verrucosa, both of which have previously been confused with S. aspera .</p><p>Sabdariffa verrucosa is closely allied to S. cordofana in having epicalyx lobes with distinct marginal ribs but S. verrucosa has leaves variously entire, shallowly lobed or deeply lobed as the plants mature ( v. climax leaves consistently 3–5-lobed for at least half the length), large ( v. small) scattered aculei on the stems, and the epicalyx and calyx with a few stiff hairs and long, very prominent aculeli on margins and ribs ( v. epicalyx and calyx glabrous except for large, prominent aculei on the margins).</p><p>Distribution</p><p>Senegal, Guinea and Mali, and probably extending south to Ghana and east to Niger but a comprehensive review of specimens will be required to determine the distribution.</p></div>	https://treatment.plazi.org/id/03AC0268C326D502FC8EFEFC9BF2FDC8	Public Domain	No known copyright restrictions apply.

We key out H. keilii based on the distinctions noted by Ulbrich (1924, p. 682) but further collections are clearly needed to ascertain the status of this entity.
