A small tree of 12 to 15 ft., with a trunk of 4 in., or occasionally of 

 nearly 6 in. in. diam. at the base. In the denser more elevated forests 

 of Sobato Quilongo Quiacatubia, apparently quite wild, but perhaps 

 originally introduced, sporadic ; fl. end of Jan. 1855. A small-leaved 

 form. No. 532. In the forests of the district, where it is used by the 

 inhabitants as a red dye and called " Quissafu " ; it is the " UrucA " of 

 the Brazilians. Coll. Carp. 116. Sobato Mussengue Dec. 1854 ; fruit. 

 Coll. Caep. 218, 219. A small tree of 8 to 12 ft. ; seeds dyeing red ; 

 Bango, middle of August 1856. Native name " Diteque." Fruit. 

 Coll. Carp. 220, 221. 



The natives call this bush " Quisafu," and employ its seeds to prepare 

 a red or yellow dye for various cloths that are fabricated from the 

 leaves of palms ; moreover, the little baskets (balayos) of Pungo 

 Andongo, which are made from the straw of a species of Eleusine, 

 and which form one of the most valuable industrial productions of the 

 people, owe part of their bright colouring to the dye prepared from the 

 seeds. Among the negro medical men the seeds are reported as par- 

 ticularly stomachic. It must be considered to be perfectly acclimatised 

 in Angola, since in not a few localities in the mountainous districts it 

 occurs as a luxuriant plant, in company with other indigenous shrubs 

 or small trees. (See Welw. Synopse p. 47.)
