Obs. Asclepias cordata, Forsk. Arab. p. 49, and 

 Cynanchum extensum, J acq. ic. 1. t. 54, are 

 the only certain species of the genus : from the 

 latter, Asclepias scandens, Palis. Hor. D'Qwar, 

 1. p> 92. t. 56, is probably not distinct, and 

 Cynanchum bicolor, And* Repos. 562, is very 

 nearly related to it.
