Phylogenetics of South American Asclepiadoideae (Apocynaceae)

Taxon, 2006
AbstractAccording to analyses of plastid DNA, New World Asclepiadoideae (Apocynaceae) fall into four clades; most species, however, are included in just one clade endemic to the New World that comprises Metastelmatinae, Oxypetalinae and Gonolobinae (the MOG clade).

Taxonomic dissolution of Sarcostemma (Apocynaceae: Asclepiadoideae)

Kew Bulletin, 2012
Since molecular analyses have demonstrated that Sarcostemma R. Br. is deeply nested in the predominantly Madagascan stem-succulent clade of Cynanchum L., the genus has been treated as a synonym of Cynanchum. Some of the former Sarcostemma species have been transferred to Cynanchum in the course of various Flora treatments, and some new species ...

Dissolution of Cynanchum sect. Macbridea (Apocynaceae‐Asclepiadoideae)

Nordic Journal of Botany, 2002
As a consequence of the recently established polyphyly of American Cynanchum (Apocynaceae—Asclepiadoideae), the former section Macbridea is analyzed in detail using molecular, karyological and morphological data. Three of the five species,

Origin and early evolution of Ceropegieae (Apocynaceae-Asclepiadoideae)

Systematics and Biodiversity, 2016
The first-branching lineages of the tribe Ceropegieae, Anisotominae, Leptadeniinae, and Heterostemminae, are the focus of the present study. In the ingroup we molecularly analysed 34 samples from southern and (north)eastern Africa and Asia for the nuclear internal transcribed spacer (ITS) region, and five plastid markers (trnT-L, trnL-F and trnH-psbA ...

New combinations in Ceropegia (Apocynaceae, Asclepiadoideae, Ceropegieae)

Recent phylogenetic studies and reconstructions (Bruyns et al., 2017) included Boucerosia Wight & Arn., Brachystelma R.Br., Crenulluma Plowes, Desmidorchis Ehrenb., Monolluma Plowes, Sulcolluma Plowes and Stapelia L. under the genus Ceropegia L. Following the current circumscription and systematics of the genus Ceropegia L., nine new combinations and a

New combination in Ibatia (Apocynaceae, Asclepiadoideae, Asclepiadeae)

A new combination is proposed here for Stelmagonum holtonii Vail under the genus Ibatia Decne. as Ibatia holtonii (Vail) R.Kr.Singh, Arigela & Sanjeet Kumar. Additionally, to fix the identity and to avoid the misapplication of name Stelmagonum holtonii Vail, a lectotype is designated here.
