Mr. Brown, and presents a critical \iew of the scientific 

 history of the species. 



We understand that three species of Artabotets, besides 

 the present, are already known, one of which with curiously 

 small flowers has been recently discovered by Dr. Horsfield 

 during his residence in Java, and is in the rich Her- 

 barium that gentleman has brought to this country.

Cryptostegia is founded upon a single species, native of 

 the Peninsula of India, where it was first observed by 

 Dr. Roxbm-gh, and strangely mismatched by him with the 

 species of the genus JVeri/an, belonging to the Apocynea^; 

 while our plant belongs to the third section of Mr. Brown's 

 Asclepiadea, distinguished from the other sections by 

 fvranular solitary pollen-masses and filaments which are
