68 The Timbers of British Guiana. 



Uses, Qualities, etc. " Is readily procurable, and should be 

 capable of being used much as Mora, No. 65. The Indians use it for 

 their arrow-points " (2). Firm, somewhat hard to saw. Fissile, 

 takes nails badly; planes and turns hard but well; polishes 

 indifferently. A useful wood as a substitute for Bullet-wood. If 

 durable (which is uncertain) it would make good paving-blocks. 

 Sometimes confused with Mora, Mora-bucquia and Morakokuru on 

 account of the similarity of the names, and with Bullet-wood on 

 account of the resemblance in the structure.

ANATOMICAL CHARACTERS. 



Those of Bullet-wood, No. 12, with the following differences. 

 (See also 27a., PL X., fig. 83, in which, however, the Pores are less 

 distinctly shown). 



Transverse Section. A little darker in shade than the other 

 sections. 



Pores. Readily visible with the naked eye, the tree-like 

 arrangement being conspicuous in the dark wood. When moist, 

 they are less visible. It is almost impossible to detail any points of 

 difference between this species and Bullet-wood, apart from the 

 colour, wliich is variable. The branching strings of Pores perhaps 

 occupy less space than in the latter wood, where they occupy about 

 half of the transverse surface of the wood. They are more con- 

 tinuous in Mora-balli than in Hymarikushi, No. 40. They are less 

 bold and striking, while the Soft Tissue is rather more regular and 

 better developed than in Mamooriballi, No. 61. 



Type Specimens. Authenticated by Bell, No. 66/2722. 



67. NOT IDENTIFIED. 



Nat. Ord., LEGUMINOS.B. Near DIMORPHANDRA MORA. 

 Native Name, '' MORABUCQUIA " (2). 



Salient Features. A hard, very close-grained, heavy, reddish 

 wood, inclined to be stripy. Pores prominent on a Transverse 

 Section. 



Physical Characters. Weight (so far recorded), 61J-67 Ibs. per 

 <jubic ft. Hardness, Grade 4, hard; compare Yew or Hornbeam. 

 Smell 0. Taste bitterly astringent; powerful. 



Colour of Heartwood red, uniform, the colour being made up of 

 red, white and brown lines. Surface bright, almost lustrous. 

 Darkens but little on exposure to the air; well, but not sharply, 

 defined from the Sapwood. The latter is light brown, and 1-1J ins. 

 wide. 



Bark. About ^ in. thick, smooth, hard, woody, of one layer. 

 Shows red, conical rods in Transverse Section, the large ends out- 

 wards opposite the ends of the Rays of the wood (needs lens) ; flakes 

 in irregular scales exposing red patches. Surface of log beneath 

 Bark, finely striated.
