74 The Timbers of British Guiana. 



73. NOT IDENTIFIED, 



but there is a marked resemblance between the wood of this species 

 and that of Pentaclethera filamentosa, though not of the fruit 

 and leaves. 



Nat. Ord., LEGUMINOS^E. 



Alternative Names. " Purpleheart, Kooroobooelli " (2);. 

 " Kooroobovilli " (20). Not the " Purperhart." 



Salient Features. A coarse-grained, medium hard, reddish 

 brown wood; cross-grained; resembles Mahogany. Nothing like a 

 the Purpleheart of Commerce, which is No. 74. 



Physical Characters. Weight (so far recorded), 44 Ibs. per 

 cubic ft. Hardness, Grade 5, rather hard; compare Ash or Elm. 

 Smell or taste 0. Does not become purple on exposure to the air ( ?). 

 Surface, lustrous and dull in patches. Sapwood, oatmeal-colour; 

 width about 1 in.; well, but hardly sharply defined from the 

 Heartwood. 



Bark. About J in. thick, like that of Beech. In two separ- 

 able layers, smooth, brown, fibrous and rather hard within ; the 

 outer much harder. Surface of log under bark, finely ribbed. 



Uses, Qualities, etc. Planes and turns well and easily, but 

 rapidly takes the edge off tools ; hard to saw. Fissile ; rends easily ; 

 takes nails badly; troublesome on account of its open grain, but 

 finishes well. Sometimes confused with the other Purplehearts, 

 as the systematic name Copaifera has long been applied to all of 

 them. This is more especially the case with Koorooballi or Trysil, 

 No. 55, as the resemblance of both name and wood seldom fails 

 to create confusion. In fact, these two woods are difficult to dis- 

 tinguish even when laid side by side. In the literature of the 

 subject one can never be sure to which wood an author refers. 



Authorities. 2. Bell, p. 9. 7. DaGama. 20. McTurk. 



ANATOMICAL CHARACTERS. 



Exactly those of No. 55, which see. Compare also No. 39,

N.B. This is not the Purpleheart which is sold as such on the 

 English market. (See No. 74 for that wood.)
