XX. HYPERICINE^. 



Nearly all the plants of this Natural Order in Angola proper 

 belong to Psorospermmn or to allied genera, and the majority 

 of the species form handsome trees of middle size, with glossy 

 evergreen foliage; the trunks abound in a kind of resin of a 

 blood-red colour, and the bark furnishes the natives -with a 

 remedy in much repute against marsh and other fevers; the 

 negroes of Golungo Alto call these trees " MutCine," and those 

 of Pungo Andongo give them the name of " M-Bulambia " 

 (Welw. Apont. p. 560, n. 140).
