Description of the wood from specimens Nos. 3007 (Empire 

 Timber Exhibition, 1920), 3298 (from Oni) and 3621 (from 

 Lagos), all " Awun," received from the Government of Nigeria. 

 Our specimen 2829 HS. "Sindru," from the Gold Coast, 

 agrees. 



GENERAL CHARACTERS. A comparatively soft and light 

 wood, of a quite uniform pale oatmeal colour which deepens but 

 little on exposure. Surface clean, but likely to soil ; warm to 

 the touch. Grain, medium, open and straight. Shade of the 

 transverse section little if at all different from that of the 

 other sections. Smell, faint, slightly recalling fuller's -earth. 

 The wood resembles that of the European white- wooded Poplars. 



STRUCTURE, Transverse section. (Prepared with pumice- 

 stone.) 



Parenchyma of apparently two kinds : (a) vasicentric and 

 another kind of uncertain nature. 



Parenchyma (a) sheaths the vessels rather narrowly, visible ? 

 colour, inclining to oatmeal, very light. Hopkinson says (1912, 

 p. 445) only metatracheal parenchyma, i.e. the following : 



Parenchyma (b) in fine, nearly continuous, concentric lines 

 which touch the pore-groups in as many as three places. Width 

 of the lines equal to about that of the rays ; intervals rather 

 more than that between the rays ; evenly distributed through- 

 out the ring, but more readily visible in the hard wood near 

 the boundary. 



Vessels visible by means of the P. (a) surrounding them, 

 medium in size, diminishing little if at all in size or number. 

 Somewhat evenly distributed, but there is a slight tendency to 

 oblique lines. Simple, or in very characteristic groups of 2-10 

 pores, otherwise widely isolated. Shape, roundish. Propor- 

 tion of the wood, not much more than one-eighth. Number 

 per sq. mm. 111. 



Rays visible at arm's length ; of one kind only ; colour
