A low tree 15 to 30 feet high, common on most of the islands, inhabiting the 
forests of the lower regions. On Oahu it is a common feature of the vegetation 
back of Tantalus and adjoining valleys. Unlike the other species, it is moisture 
loving, and forms large clumps in the valleys on the windward side, where the 
rainfall is very large. Logs of this tree, which the writer collected for wood 
specimens, shriveled to such an extent that it was impossible to recognize them 
afterward, resembling the stems of shriveled banana plants. Trunks of a foot 
in diameter can be felled with one stroke of the axe. It is of a very wide geo- 
graphical distribution, ranging from Polynesia to Australia and the Philippines. 
On Oahu it is found at an elevation of 200 to 1600 feet, and possibly higher. It 
Is very difficult to find good specimens on account of an insect which feeds on the 
leaves, and thus most of the trees have a very ungainly appearance.
