timber has been named. It is much harder and has little resin 
canals typical of the order. It is not attacked by white ants. 
It reaches a height of 100 feet, with a bole length of about 
40 feet and a girth of 12 feet. The root spurns are only slight. 
The large, elongated, spherical-shaped fruit, with rough, pale 
orange-coloured rind, speckled brown in several places, is most 
typical of this tree. Generally speaking, it could easily be 
mistaken for Mahogany Entandrophragma by anyone not very 
familiar with both species. 
Timber.—The sapwood is white, with a pinkish tint, and the 
heartwood a dark red, with small medullary rays as well as 
very prominent resin-like canals which, when dry, are filled 
with a yellow substance. 
Silvicultural Qualities. —It is a shade-bearer, but likes a 
certain amount of overhead light in middle age. On the whole 
it is slow-growing, except for a short period when the chief 
height-growth is put on. A few stump shoots sprout when the 
tree is cut down, but the more common form of reproduction is 
by seed. 
Viility.—It has not been felled for export, but the Public 
Works Department felled and converted a good deal at the 
Etehetem sawmill, and it was favourably reported on as a hard 
mahogany. It has occasionally been used by the natives for 
making canoes.
