Taxonomic dissolution of Sarcostemma (Apocynaceae: Asclepiadoideae) by Ulrich Meve & Sigrid Liede-Schumann- Kew Bulletin 12/2012; 67(4).
ABSTRACT : 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 belonging to this radiation have been described under Cynanchum. The present contribution serves to complete the formal transfer of Sarcostemma taxa to Cynanchum, in which a total of nine species are concerned: Cynanchum arabicum, C. areysianum, C. brevipedicellatum, C. daltonii, C. forskaolianum, C. mulanjense, C. pearsonianum (a substitute name for Cynanchum pearsonii), C. sarcomedium (a substitute name for C. intermedium), and C. socotranum. In addition, six subspecies of Cynanchum viminale are newly combined: C. viminale subsp. australe, C. viminale subsp. brunonianum, C. viminale subsp. orangeanum, C. viminale subsp. stocksii, C. viminale subsp. thunbergii and C. viminale subsp. welwitschii. Finally, notes on recent introductions from southern Yemen are made, and illustrations of Cynanchum areysianum are provided.

Pl. go through ‎Cynanchum (‎‎Apocynaceae) page with images of species (done by me) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.

Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
