28 GUIDE TO TIMBERS OF NIGERIA 



Radial section. Vessels appear as large grooves, sometimes 

 twinned ; contain much nearly black resin or gum. Paren- 

 chyma (a) very scanty, visible with difficulty with lens. P. (c) ?, 

 but there are certain lines heavily charged with gum that 

 look like boundaries. Rays readily visible as small dull flakes, 

 like pink chalk. 



Tangential section as the radial, but the rays are only just 

 visible as fine, short, pink lines producing a matt effect, being 

 dull against the shining fibres of the ground ; height about 

 twelve cells, but very variable in both height and width ; 

 uniseriate rays not common, and up to six-seriate present ; 

 not in parallel ; shape symmetrical, or only very slightly 

 distorted ; gum globules visible with macro. Vessels often 

 oblique. 



Density, No. 3103, 0-594 or about 37 Ib. per cubic foot. 



Bark, sapwood and pith absent from our specimen. 



USES, ETC. An excellent quality of Mahogany and suitable 

 for all purposes to which that wood is usually put. 



Lovoa Klaineana (Pierre MSS.), Sprague. Meliaceae. Gen. 

 No. 1198c. 



NOTE. The determination of the species is uncertain. A 

 specimen received as " Apopo " or " Anamammilla " (Pseudo- 

 cedrelasp.), No. 2904 HS., from Southern Nigeria, is certainly 

 the African Walnut, best known to commerce. H. N. Thompson 

 (1908, p. 90) says that " Apobo, African Walnut, or Anamam- 

 milla is a species of Pseudocedrela" and that the colour of 

 the wood is " rich Walnut-brown." Unwin (1920, p. 100) 

 cites a " Pebedum " as being Lovoa Klaineana, and describes 

 the wood as " Walnut-brown, sometimes with striking black 

 streaks," which tallies admirably with our specimens, the 

 black streaks, produced by gum-galls, being unusual and a 

 particularly characteristic feature. Specimen No. 3620, sent 

 to us as Guarea from Benin, is so like this species that we 

 hesitate to come to a decision. Amongst our specimens 

 Nos. 1839 HS. " Enonee " from a commercial source, 1897 HS. 

 " African Walnut," 1887 HS. " African Mahogany " agree with 

 each other and are probably the same as our type. The last 

 mentioned is a piece of the same wood with which the fittings 

 of Emmanuel College, Cambridge (North Court) were made.
