~ ¢overed with whitish tomentum which mostly disappears with maturity. Wood 
at first somewhat angled becoming cylindrical; at first green, becoming dark, 
dull reddish-browmm; bark of Old wood rather finely checked and persistent; on 
young wood after first year, flaking off cesily, leaving curface beneath of a 
glossy reddish-brown color; wood firms nodes swollen, straight; diaphragm 1/16"
