Description of the Woods in the Collection. 53 



ANATOMICAL CHARACTERS. 



Similar to those of the Cedrelas (Stone 27a. PL III. fig. 23),. 

 and our No. 14 Frontispiece. 



Transverse Section. Considerably darker in shade than the 

 other sections. 



Pores. Just visible with the naked eye as fine perforations; 

 scarcely diminishing towards the close .f the season's growth; if 

 anything, the converse is the case. Little variation. Evenly distri- 

 buted, widely scattered; very few; single or in radial groups of 

 2-4. 



Eays. Visible with the naked eye (when moistened) ; irregularly 

 spaced, mostly less than the width of a Pore apart and avoiding 

 them. 



Rings. Well defined ; boundary in a fine line of Soft Tissue, 

 readily visible to the naked eye; contour regular. Number per 

 inch of radius averaging 11' 8. (In my specimen one Ring is over 

 J in. wide). 



Soft Tissue of definite arrangement; type of Cedrela and 

 Mahogany, i.e., the fine, light coloured boundary line (? encircling 

 the Pores also). 



Pith.( ?) 



Radial Section. The Pores are prominent, though small, dark 

 grooves. The Rays are narrow, brown lines which show up con- 

 spicuously against the brilliant ground. The Rings are scarcely 

 visible. 



Tangential Section as the Radial, but the Rays are minute, 

 brown lines which give the section a sort of " half-tone " appear- 

 ance ; they are about '2 m/m. high. 



Type Specimens. Authenticated by Bell, No. 51/2707. 



52. NOT IDENTIFIED. 



Native Name, l( KOKATARRA " (2). 



Salient Features. A very soft, light, white wood with a yellow- 

 ish silver-grain. 



Physical Characters. Weight (so far recorded), 38 Ibs. per 

 cubic ft. Hardness, Grade 8, very soft; compare White Pine. 

 Smell 0. Taste astringent. Apparently a Sapwood tree. My 

 specimen which is from a tree 8 ins. in diameter is all Sapwood. 

 Darkens a h'ttle on exposure to the air. Surface lustrous in Radial 

 section. 



Bark. About J in. thick, brown, of one layer, crumbling. 

 Pitted externally (with wart-like lenticels). Surface of log 

 beneath bark, smooth or striated. 



Uses, Qualities, etc. " Very small sizes short wood not 

 used " (2). Saws easily. Fissile, takes nails badly; planes and 

 turns easily and moderately well; polishes indifferently. Of no- 

 export value.
