GUIDE TO TIMBERS OF NIGERIA 73 



of about 1-2 times their own width ; colour, yellowish- brown, 

 rather darker than the P. (a). Straight ; number per mm. 

 10-18. Contents, some red resin. Proportion of the mass at 

 least one-third. 



Ground-tissue-cells visible with the macroscope ; proportion 

 of the wood about one-half. 



Rings very vague, the darker zones may indicate the boun- 

 daries. 



Radial section slightly mottled by the silver-grain which 

 covers about half the surface and is more or less visible according 

 to the incidence of the light, being quite dark in one light and 

 almost invisible in another. Grain, open, with characteristic 

 red globules here and there. Parenchyma (a) visible as hoary 

 borders and tails (less so with lens). The cells of the wood- 

 fibres are clearly visible with the macroscope, as are also those 

 of the rays ; the former are in parallel. The resin in the ray- 

 cells sometimes forms continuous lines resembling the resin- 

 parenchyma of conifers. 



Tangential section as the radial, but the rays are minute 

 vertical lines from one to two or even three cells-wide, and up 

 to thirty high. The red resin appears as fine points in both 

 rays and vessels, and even with the naked eye the globules 

 appear as glistening points in a brilliant light.
