 Nearly related to V. obconica 0. & H. It is a medicinal plant, and 

 in G-olungo Alto is called " Caliilu " ; the dried and rubbed leaves 

 are employed by the native medical men for curing ulcers. According 

 to a note of Welwitsch it occurs also in Pungo Andongo. The name 

 calulu, printed catulu by Ficalho, I.e., probably in the native language 

 means bitter.
