164 WEST AFRICAN FORESTS AND FORESTRY 



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 

 verj' 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 sloAv-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. 



Utility. — 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. 

 No botanical name. Oshusi (Ibo, Owerri). 



Distribution. — It is found in the Owerri province of Nigeria. 

 It is a comparatively common tree in the evergreen swamp 

 forest. 



Characteristics. — The timber is not over hard, but it reaches 

 a height of 100 feet and a girth of 8 feet. The bark is smooth. 



Silvicultural Qualities. — It is a shade-bearer and a com- 

 paratively slow-growing tree. The most prevalent form of re- 

 production is by seed. 



Utility. — It has not been felled for export, but was used in 

 the construction of the Imo railway bridge as piles. 

 Buronona (New Calabar). 



This is a medium-sized tree of the Owerri province, and is 

 found near the Imo, not far from the railway bridge. Several 

 piles of the temporary bridge were made from the timber of 

 this tree.
