Zenza do Golungo. — An immense tree ; wood blood-red, that of 

 the root more deeply coloured ; called by the native negroes " Lucula," 

 and by the Portuguese colonists " Tacula." Sporadic, in open rocky 

 woods between the village of Calumguembo and Tanderachique ; with

Lichen n. 415 grew on the trunk of this tree. It is said that here 

 the wood is more compact and the red dye faster than in the mount- 

 ainous districts. The dust from the pounded root is always preferred 

 to that from the trunk, as it contains a higher proportion of colouring 

 matter.
