When Mr. Brown remodelled the order of Apocyne^e in 

 1809, he pointed out the Echites succulenta and bispinosa, 

 two remarkable Cape planis, which he had had no oppor- 

 tunity of examining, as likely to constitute a distinct genus. 

 In this opinion, the plant now figured shews that he was 

 right. It evidently differs from Echites, in the segments of 

 the corolla being equal-sided, and in the want of hypo-

 stem and swollen root.
