Description of the wood from a specimen received from the 

 Government of Nigeria, No. 3102 " Apa " (Empire Timber 

 Exhibition). Our specimens, No. 0740 HS. "Bamba-kofi'' 

 from the Malindi District, British East Africa, No. 3095 

 (McDonald) from the Gold Coast, agree, but Nos. 2823 

 " Opepea " from the G.C. sent as this species does not, nor 

 does No. 3797 " Bilinga " from a commercial source. No. 3018 

 " Papow ; Papao " from the G.C. (Empire Timber Exhibition) 

 is very close if not the same wood. We include a description of 

 No. 2823 as it may possibly be correctly identified. (See p. 40.) 



GENERAL CHARACTERS. A rather heavy, hard wood of a 

 golden-brown colour streaked with darker and lighter zones 

 and showing a feather-like tracery in tangential section. 

 Colour deepens considerably on exposure : " Rich Oak-brown " 

 (Unwin, 1920, p. 292). Grain, moderately coarse and open, a 

 little inclined (cross). Surface not cold to the touch, dry. 

 Shade of the transverse section a litle lighter than that of 

 the others, there being much pale soft-tissue (parenchyma). 

 Smell, none. Not likely to soil. 



STRUCTURE. Resembles that of many leguminous woods 

 such as Mora. 



Transverse section. (Prepared with the plane.) 



Parenchyma of two kinds : (a) vasicentric and (c) simulating 

 the ring-boundaries. 



Parenchyma (a) readily visible, abundant, giving the light 

 tone to the section, sheathing the pores, forming for the most 

 part lenticular patches, and extending obliquely and joining 

 up 2-5 pores or pore-groups ; also in a concentric direction,
