 sometimes becoming leaf-opposed by the development of a terminal shoot. 

 Male sepals about 4 lines long. Capsule ^ in. long or more. 



In waste places, Seemann and others. A native probably of western Asia or Africa, but so 

 nuich cultivated and sowing itself so readily that it has become a common weed in many hot 

 countries. It supplies the castor oil.

Hongkong, Hance. Not seen from elsewhere. It is allied to Wallich's n. 8001, fi-om 

 Silhet, but that has longer leaves decurreut on the petiole, looser racemes, larger female 

 fljwers, a more deeply divided style, the ovary glabrous. It has no connection with C. longi- 

 folium, Wall., which is a Tngonostemon.
