Nearly related to V. obconica O. & H. It is a medicinal plant, and 
in Golungo Alto is called “ Calilu” ; 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, /.c., probably in the native language 
means bitter.
