This is undouL.cJly a species of Aoerates ot Elliott^ 

 though, as the -vufhor himself thinks, n is doubtful whether 

 that genus be sufficiently oistinct from Asclekias. It diifers 

 from the latter principally in the sessile atr<*ig!it nectary leaves, 

 and in the absence of their horn-like prcrcsses. om the 

 GoMPHOCARPUst if R' Bro w n, it only diflci-sin the sm-Jth 

 follicles.

 cimens were too much hijured to determine whether the horr 

 like appendages were present; otherwise he would undoati-
