The Ohia lehua is the most prevalent tree in the forests of the islands of the 
Hawaiian archipelago. It ean be found from sea-level to an elevation of 9000 
feet. It certainly deserves its specific name polymorpha as it is the most vari- 
able tree which the Islands possess. On the summits of Kohala, Hawaii, Mt. 
Waialeale on Kauai, and Puukukui, West Maui, which have an elevation rang- 
ing from 5000-5600 feet, it is a creeper, only a few inches in length, though 
flowering. It grows in company with native violets, geraniums and sundews 
(Drosera longifolia) while in the middle forest zone it becomes a giant of often 
100 feet in height, with a trunk of several feet in diameter. At the seashore, as 
for example at N apoopoo, Hawaii, it is a stunted gnarled tree 10-15 feet in height 
growing on ancient pahochoe lava in company with Reynoldsia sandwicensis 
the Ohe kukuluaco of the natives, and other trees. On the windward side of 
Hawaii, not far from Hilo, it covers the vertical cliffs down to the water’s edge, 
but does not attain any size. Its best development and the largest forests 
composed of this tree are found on the voleanic slopes of Mauna Loa and Mauna
