84 The Timbers of British Guiana. 



82. NOT IDENTIFIED. 



Native Name, " SIRIBIDANNI " (2). 



Salient Features. A hard, heavy, purplish wood; fine-grained 

 and dense; cold to the touch. 



Physical Characters. Weight, not recorded. Hardness, Grade 

 3, very hard. Smell 0. Taste 0. 



Colour of Heartwood "purplish" (2). Sharply defined from 

 the Sapwood ; darkens little, if at all, on exposure to the air. Sap- 

 wood yellowish, suggesting Boxwood ; width 3-4 ins. The width of 

 the Sapwood is almost the only character, expressible in wordi, by 

 which this species can be distinguished from Bania and Wamara. 



Bark. ( ?) Surface of log beneath Bark, smooth or striated. 



Uses, Qualities, etc. "A furniture wood. Is scarce and not 

 procurable except in small sizes" (2). "Plentiful in some local- 

 ities average height about 50 feet, and it will square free of sap 

 4-6 ins." (20). Rather hard to saw. Fissile, takes nails badly; 

 planes fairly well; turns moderately hard but well; polishes 

 indifferently. If the sample sent is of average quality this wood 

 is much inferior to Bania and Wamara, and of no value for export. 

 Frequently confused with the two last-named woods, Nos. 6 and 92, 

 on account of similarity in colour, structure and appearance 

 generally, and by name with Nos. 76 and 78.

ANATOMICAL CHARACTERS. 



The same as those of Wamara, No. 92, with the following slight 

 differences, which I give for what they are worth. 



Transverse Section: 



Pores. Readily visible with the naked eye on account of their 

 lighter colour. 



Radial Section. The Pores have no shining black contents. 

 The Soft Tissue is visible in certain lights as fine, brown striae. 



Type Specimen. Authenticated by Bell, No. 82/2738.
