GUIDE TO TIMBERS OF NIGERIA 41 



globules ; proportion of the wood (excluding the Parenchyma) 

 very small. 



Rays just visible to the unaided eye on account of their 

 light colour, small ; of one kind only ; slightly nodose where 

 they cross the bands of parenchyma ; fairly regular in size 

 and spacing ; intervals about four times the width of a ray ; 

 number of rays per mm. 6-8 ; colour, pinkish and rather darker 

 than the parenchyma. Proportion of the wood about one-fifth. 



Ground-tissue-cells just visible with the macroscope ; colour, 

 dark brown and horny. Proportion of the wood rather .less 

 than one- half. 



Rings : No certain indication. 



Radial section. Vessels very rare, coarse, often twinned and 

 even in fours side by side, occasionally strongly bent or curved ; 

 contents scanty, mostly masked by the parenchyma. Paren- 

 chyma very easily visible, composing half the surface in long, 

 parallel, buff-coloured lines. Rays readily visible flakes, not 

 contrasting very much with the parenchyma, but rather more 

 with the ground tissue. 



Tangential section as the radial, but the rays are too small 

 to be visible with the unaided eye except as a slight matt 

 effect ; not in parallel ; very variable in height and width ; 

 14 rows wide (mostly two-seriate) and very thin for their 

 height, which may run to more than Ij mm. 



Density, No. 2823, 0-804, or about 50 Ib. per cubic foot.
