1. R. temie (Arn.) foliis lineari-filiformibus margine revoiutis. 

 Ad Caput Bonse Spei legit CI. Harvey (Herb. Harv. n. 629.) 



This genus is allied in character to Xysmalobiutn, also from the 

 Cape^ but that is destitute of the projecting toothlet, which arises 

 in this from the inside of the coronal leaflets. Cynanchum Jiliforme 

 Thunb. is apparently another species with broader and flat leaves. 



Besides the present;, I have received only two other Cape species 

 of Asclepiadeae from Mr Harvey : one is Cynanchum pilosum, R. Br. 

 (Herb. Harv. No. 413.) : and the other Secamone Alpini, R. and S. 

 (Herb. Harv. no number.) 



In Wight's " Contributions/' and Decandolle's fifth volume of 

 the " Prodromus/' two plants are referred to the genus Blepharis- 

 permum ; but on account of the specimens of one of them being im- 

 perfect, the character was principally taken from B. petiolare. 

 More lately, having received additional specimens of B. subses- 

 slle from Dr Wight, I am now enabled to describe it more fully ; 

 and as it cannot be conjoined into one genus with B. petiolare, 

 (unless indeed Athroisma be also united,) I shall here give the re- 

 formed character of Blepharispermum, as well as of the new one.
