Jacg. Ic. Ear. t. 560 ? 



HAB. Native of the East Indies. Cultivated in gardens to 

 cover arbours. 



FL. September. 



Stem suffruticose, lasting for several years: branches gla-

 apex acute, glabrous. Racemes longer than the leaves, pendu- 

 lous. Flowers erect, upon short pedicels, of a pink colour

 Seeds of a rufous colour, size of a pigeon's egg, rattling when 

 ripe in the pod.

 mens with which I have met.
