Abstract

Two lesser-known climbing asclepiads—Cynanchum corymbosum Wight and Oxystelma esculentum (L.f.) Sm.—of the family Apocynaceae, sensu lato, have been recollected from Assam, India after a gap of 67 and 87 years, respectively. A detailed taxonomic account, colour photo plates, and a map showing the collection sites in Assam has been provided. This recollection highlights the importance of continued botanical exploration and conservation efforts in the region.
