This is a variable species ae presumably occurs on the whole Koolau range. 
It was collected by the writer in Manoa and Pauoa valleys, also in Nuuanu Val- 
ley, on Konahuanui, Mt. Olympus, and especially Palolo Valley, where it is ex- 
ceedingly common. In Niu Valley occurs a plant which agrees fairly well with 
those from the mountains back of Honolulu; the leaves are little shorter and not 
acuminate, neither are the capsules rough, but smooth and more or less oblong 
rather than subglobose. It must, however, be referred to this species. 
It is a small tree 15 to 20 feet high and is peculiar to the rain, as well as the 
drier forests of the main mountain range of the island of Oahu at an elevation 
of 2000 feet.
