Description of the .vood 



Sapwood thick, nearly white; heartwood very dark red 

 with faint streaks of black to rosewood ( Dalbergia nigra ) . 

 Wood hard, heavy, strong and tough, fine and cross grained, 

 rather difficult tt work, but taking a good polish and du- 

 rable in contact with the soil. Annual rings of growth 

 not visible even under the high pov/er microscope. 



Pores (transverse section) very few, (.BIO mm. in dia- 

 meter), round or radially elliptical, open in sapwood, closed 

 with dark red tyloses in the heartwcod, and arranged singly 

 or sometimes in pairs. Vessel walls (longitudinal section) 

 with numerous, small bordered _tjits and a few transversely 

 elongated simple pits, ■'•''erfc! rat ions simple. :Iood libers 

 about 1.02 mm. long, with thick walls and small luraina , 'Uid 

 very small, slit-like, oblique simple pits, v/ood parenchyma 

 rather aoundantly developed, but visible only under compound 

 microscope as very minute irregular tangential lines of a 

 single cell in width. Hays very incionspicuous, .ui^y one 

 cell v.ide or sometimes two and from a few to 8 or 10 cells
