62 GUIDE TO TIMBERS OF NIGERIA 



Density, No. 3618, 0-74, or about 46 Ib. per cu. ft., but it 

 is partly sapwood. Sapwood only works out at 0-69. 



PITH. Hoary, about 8 mm. wide (at the node) ; contains 

 many minute amber beads. 



SAPWOOD. Light citron-yellow ; well denned ; much darker 

 in transverse section. Very wide. 



BARK. Greyish-brown, very fibrous with shallow, vertical 

 fissures with a tendency to break up into scales ; thickness of 

 specimen, about 4 mm. ; much stringy bast, which is fairly 

 strong. Fracture of bark, fibrous ; scleroses small, rare, in 

 the outer zone of the bark. 



USES, ETC. The heart wood is of a beautiful colour and very 

 close-grained and compact. If it could be seasoned without 

 cracking it would make an excellent turners' wood and could 

 be utilized for many purposes for which boxwood is employed. 



Adina microcephala, Hiern. Rubiaceae. Gen. No. 3004. 



Synonym. -Gilg (p. 131) cites A. microcephala (Leprieur et 

 Guill), K. Schum, from the Cameroons, and states that the 

 wood is whitish-yellow. Is this a different species ? 



LOCALITIES. Togo, Nile-land, Nigeria, French Central 

 Africa, Portuguese East Africa.

Description of the wood from a specimen No. 3010 " Kadenya 

 rafi " (Empire Timber Exhibition, 1920) received from the 

 Government of Nigeria. Our specimen No. 2906 HS. " Nikiba ; 

 Osikiba" from S. Nigeria and No. 3337 "Mwenya," from 

 Nyasaland agree in all essential details. Nos. 2814 HS. " Affna 

 sappa ; Affna " from the Gold Coast and 2916 " Sarutu " 

 from the Ivory Coast are near, the former connecting the 

 Swamp Opepe with this species, indeed Swamp Opepe more 

 closely resembles Adina than it does Sarcocephalus. 



GENERAL CHARACTERS. A rather hard and heavy wood of 

 a yellowish-brown colour with darker stripes and flakes. 

 Colour deepens considerably on exposure. Surface dull, rather 

 cold to the touch and a little clinging (" oily feeling " Unwin, 

 1920, p. 145 ; also Volkens, 1901, p. 26). Very fine and cross-
