leaves. They both appear to be species of Chytroma (Lecythis). 



For the present purpose we have assumed that the fruit specimen 



is from the tree which yielded the specimen of wood. 



46. NOT IDENTIFIED. 



Alternative Names. " Kakataraballi " (2); (?) " Kookerite 

 Balli " (12). 



Salient Features. A light, soft white wood with prominent 

 rays. 



Physical Characters. Weight (so far recorded), 41 J Ibs. per 

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

 Smell 0. Taste little, if any. Heartwood darkens but little on 

 exposure. Surface scarcely bright. Apparently a Sapwood tree; 

 my specimen, which is from a tree 10 ins. in diameter, is all Sap- 

 wood. Colour, dirty white; whitish yellow. 



Bark. yV'i ^ n - thick; smooth and skinny outside, crumbling 

 within. Surface of log under bark, nearly smooth or finely 

 striated. 



Uses, Qualities, etc. " Used for table drawers and takes 

 polish wJl. Readily procurable in logs up to 30 ft. in length, 

 squaring 12 ins." (2). Saws easily; takes nails well; planes and 

 turns easily but badly. Not suitable for polishing. The inferior 

 quality of my specimen may account for the difference of opinion.

ANATOMICAL CHARACTERS. 



Transverse Section. Similar in shade to the other sections. 



Pores. Visible with the naked eye, small, apparently dimin- 

 ishing regularly towards the close of the season's growth. Very 

 few; indeed, remarkably so. Evenly distributed between the 

 Hays; mostly single, with a few pairs radially sub-divided. 



Rails. Visible with the naked eye; prominent, large, uni- 

 form, irregular, the thinner portions or ends about the width 

 of a Pore apart; the middles widely separated, strong, direct, 

 not avoiding the Pores; tapering considerably. 



Rings. Not defined ; boundary doubtful : contour regular. 



Soft Tissue. Of no definite arrangement; not visible with the 

 lens. 



Pith. (?) 



Radisd Section. The Pores are fine, almost imperceptible 

 scratches. The Rays are broad, yellowish-white flakes, large but 

 not prominent, as they lack contrast. 



Tangential Section as the Radial, but without the silver-grain. 

 The Rays do not require the lens, as notwithstanding their 

 minuteness they are yet visible to good sight. 



Type Specimens. Authenticated by Bell, No. 46/2702.
