“…Former Marsdenia s.l. species of Cuba have recently been transferred to Ruehssia (Reuss & al., 2020), some species of Puerto Rico (Bárrios & al., 2020) and Mexico ( Lozada-Pérez & al., 2020), as well as all species occurring in South America and the Caribbean ( Acevedo-Rodríguez, 2021) -Plants suffrutescent lianas or rheophytic shrubs, 0.5-5 m high, shoots hollow, glabrescent (Sarcolobus pepo pubescent), occasionally with papery bark; latex white to yellow. Leaves oblong to ovate, occasionally cordate, obtuse or retuse, lamina 7À13(À15) cm long, basally adaxially with up to 6 colleters.…”

A densely sampled molecular phylogeny of the pantropical, predominantly forest‐dwelling tribe Marsdenieae (Apocynaceae) is presented, including almost a quarter of the ca. 740 species. Sampling focused on resolving the circumscription of Marsdenia, which ranges from Marsdenia sensu Bullock with less than 10 Asian species closely related to the type, M. tinctoria, to Marsdenia sensu Forster, with ca. 300 species distributed throughout the range of the tribe, encompassing the genera Cionura, Dregea, Gongronema, Gymnema, Leichhardtia, Stephanotis, and Wattakaka as synonyms. All analyses resolve two well‐supported clades: an Asia‐Pacific Clade that includes the large epiphytic Dischidia‐Hoya alliance and a number of Marsdenia species, among them the type M. tinctoria, and a Cosmopolitan Clade that includes most of the rest of Marsdenieae with several moderately to well‐supported subclades that span the entire geographic range of Marsdenieae. The position of two small genera, Rhyssolobium (southern Africa) and Sicyocarpus (Madagascar), is ambiguous. Given this topology, a monophyletic Marsdenia s.l. would subsume all species of Marsdenieae. Instead, we propose a classification that maintains Dischidia and Hoya as distinct genera. We revise generic circumscriptions, reducing Marsdenia s.str. to a small clade of Asian species. Two new genera, Gongreos gen. nov. and Gongronemopsis gen. nov., are described, with two and nine species, respectively. A total of twenty‐six new combinations, one new name, and six new synonyms are proposed. Three neotypes and eleven lectotypes are selected, and one 2nd step lectotypification is carried out. Diagnostic morphological characters for identified clades are discussed. Biogeographic analysis retrieves tropical Asia as most likely ancestral area for Marsdenieae, with widespread tropical Asia‐Africa almost equally likely. The first‐branching lineages in both major clades are tropical Asian; the Asia‐Pacific Clade comprises a sizeable radiation in the Pacific area, with two dispersals from Australia to New Caledonia. The Cosmopolitan Clade comprises several genera (Gongronemopsis, Gymnema, Stephanotis, Telosma) widespread in Africa and tropical Asia, and some also in Madagascar, and the New World genus Ruehssia.

“…However, they only provided new combinations for the Brazilian species of Marsdenia. Following their work, Liede, S. Reuss & Meve (Reuss et al 2019), transferred all species of Marsdenia occurring in Cuba into the genus Ruehssia, and Goyder (Bárrios et al 2020)…”

“…Espírito Santo et al (2019) recognized 42 species of Marsdenieae in Brazil and formally transferred 41 from Marsdenia to Ruehssia (except R. macrophylla H. Karst., the type of Ruehssia); since then, species from the rest of South America, Puerto Rico and Cuba have also been transferred to or described in Ruehssia (Bárrios et al 2020;Reuss et al 2020). Roughly one fifth of the Brazilian species in the genus (9 species) was described in the last three years (Espírito Santo et al 2018a, b, c) and most of them (6 species) are endemic to the Cerrado Domain.…”

Ruehssia quirinopolensis (Apocynaceae), a new species from the Cerrado Domain, Brazil

et al. 2021

A new species of Apocynaceae, Ruehssia quirinopolensis, endemic to Serra da Confusão do Rio Preto and Serra da Igrejinha, Quirinópolis, state of Goiás, Brazil, is described and illustrated. It resembles R. rupestris, differing by the white corolla, adaxially villose and with a longer tube, and by its corona lobes with the upper portion lanceolate. Besides a distribution map for the new species, we provide a key to identify the nine species of Ruehssia that occur in Goiás. Ruehssia quirinopolensis is assessed here as Critically Endangered (CR).
