COCOBOLA WOOD 



joining the coarse-pored Spring wood : contour gently undulating : 

 of light and dark bands. 



Soft tissue. In lines of single cells here and there : abundant. 



Pith. ? 



Radial Section. Much lighter than the Transverse section. 

 Pores just visible as brightly shining, empty grooves. Rays 

 just visible, minute, dull flakes having scarcely any contrast 

 with the ground. 



Tangential Section. As the Radial, but the rays need micro- 

 scope about 075 mm. high, of one row of cells. 



Type specimens not authenticated but reputed to be this 

 species. 



No. 209. COCOBOLA WOOD. Species unknown. 



Plate XV. Fig. 131. 



Physical Characters, etc. Recorded dry-weight 75 lbs. per cu. ft. 

 Hardness Grade 1, compare Ebony. Smell or taste none. 

 Burns unusually well with a smell recalling sealing-wax : heat 

 expels a crimson juice : embers glow in still air. Solution amber 

 or brownish. 



Grain. Coarse but close and even. Surface bright, the 

 pores shining like jet when filled with resin, otherwise dull. 



Bark.? 



Uses, etc. Turnery, inlaying, Tunbridge-ware. The showiest 

 and most strikingly-coloured of all our commercial woods. It 

 usually comes to hand in the form of small, badly-hewn logs. 



Authority. Wiesner (131), L. 12, p. 911. 



Colour. Heart- wood deep orange or orange-red streaked with 

 sharply marked jet-black lines. Sap-wood brownish-white 

 sharply defined from the heart. 



Anatomical Characters. Transverse section : — 



Pores. Conspicuous on account of their jewel-like glistening. 

 Size 1 to 2, rather coarse, little variation : fairly evenly and widely 

 scattered : single or in compact groups of 2 or 3 : very few, 

 from 0-4 per sq. mm., rarely as many as 7 : always filled with 

 amber, ruby or black resin. (A gorgeous object under the 

 microscope.) 



Rays. Need lens, size 5 to 6, uniform : equidistant, crowded : 

 very numerous, 9 to 11 per mm. : rarely tapering : denser and 

 lighter in colour than the ground-tissue : not avoiding the pores 

 but interrupted by them. 



Rings. Doubtful, but there are fine, concentric lines broader 

 than the rays that may indicate the boundaries. 



Soft-tissue. In concentric lines as above, size 5, clearly visible
