I first met with this plant in 1834, subsequently in Assam 

 in 1835-6. It appears to have been introduced into these 

 gardens, where it flowers in August and September, by Major 

 Jenkins. 



I am not aware of the immediate affinities of the genus ; the 

 fohation is that of Gymnema and Marsdenia, the corolla in 

 some measure that of Cryptolepis. It is singular, in the 

 family, in the wings of the fruit : the axillary panicles also 

 appear to be a very unusual character. In the form of the 

 processes of the corona it resembles Streptocaulon, and Fin- 

 laysonia (jure Gurua Hamilton,J but in those genera the 

 part called corona is so little developed, that the processes 

 are referred in characters to the faux of the corolla.
