(no. 1463). Indefatigable Isl. : Academy Bay, small trees 

 near the shore, one of the common forest trees above 350 ft., 

 (no. 1463); north side, trees above 1000 ft.; northwest side, 

 small trees at 150 ft., forming large forest trees at 500-800 ft. 

 James Isl.: James Bay, common trees, 450-1700 ft., (nos. 

 1464-1465) ; northeast side, trees above 600 ft. This species 

 forms one of the most common forest trees in the transition 

 and moist regions on the islands where it occurs. Hooker, op. c. 

 194, describes it as an almost leafless tree, but we found it to be 

 usually covered with a dense growth of leaves. As a rule the 

 trunk is short and the branches are large and broadly spread- 

 ing. Owing to the rough nature of the bark it is usually cov- 

 ered with epiphytes when it occurs in the moist regions. En- 

 demic.
