Cortical surface unknown, ligneous surface with puncto-striate 

 ribs l r \ inch in breadth and with single oval scars half an inch

Ribs prominent, coarsely striate, 0*35 inch wide. Scars 

 nearly as wide as the ribs, rounded hexagonal, one inch distant;

 scars single, round, oblong ; bark very thin.

 M. C. Sydney, R. Brown. 



Ribs obsolete ; cortical and ligneous surfaces striate ; vascular
