 at the base, broadly rounded at the ajjex, Z,5 to 4 cm. long, 

 E to 3 cm. bread, glabrous, dndrojjhcnim pinkish white, 

 broadening from the ring (1.6 cm. in diameter) to the galea

Descri ^ /tion of the wood 



Sapv/ood thicic and nearly v/hite; heartwood grayish brown. 

 ■,Vood relatively hard and heavy, strong, tough, cicderately 

 coarse-grained, usually crcss-grained, works fairly v/ell 

 and takes a good polish. Annual rings of growth not clearly 

 visible even under high pov/er of microscope. 



Pores (transverse section) relatively few, large (about 

 ,28 raia. in diameter), roimd, somev/hat oval ox* radially 

 flattened, open both in the s^ipwood and heartwood and arranged 

 singly, in jjairs, or in short radial rows. Vessel walls 

 (longitudinal section^) relatively thin with a number of 

 rather large irregular bordered i-'its; ^/its small and slit- 

 like -vhere they are in touch with wood fibers. The ends of 

 vessel segments with simple perforations. .Vood fibers about 

 1.4 mm. long v/ith gather thin walls and large cell cavities. 

 The pits are numerous, slit-like and yex:y minute. .ood pa- 

 renchyma abundantly developed, irregularly distributed 

 throughout the ,700d or often arranged in inconspicuous tan- 

 gential lines one cell in width. Pith rays very numerous 

 and quite G02i8picuous on the radial surface and under the 

 hand lens on a smooth transverse section. They are from a 

 feww to 5 cells v/ide and from 4 to 8 times as high.
