The Ohe ohe of Maui and Hawaii is like that of Kauai, a stately tree 50 to 60 
feet and sometimes even 80 feet in height. It has a straight bole for 30 feet or 
more, with few stout ascending branches. The trunk, which is clothed in a whit- 
ish-gray smooth bark, is often a foot or more in diameter. The tree was first 
described by H. Mann, who collected it on the Island of Lanai, recording it as 
a small tree 12 to 20 feet in height. It has since been found on Maui and Ha- 
wali. It is, however, still most numerous on the southeastern and strictly south- 
ern slopes of Mt. Haleakala, Island of Maui. In the former locality above Ulu- 
palakua it is the only species alive, as can be seen in the picture, all the rest of 
the vegetation having been killed by cattle, goats and sheep. 
On the lava fields of Auahi, district of Kahikinui, the writer found some very 
big trees in company with Pelea multiflora, Bobea Hookeri, Alectryon macro- 
coccus, Xanthorylum sp., Tetraplasandra meiandra, and many others. It is more 
or less peculiar to the dry districts, but is also not uncommon in the rain forest 
on the northeastern slope of Haleakala along the Kula pipe line trail, especially 
on the crater of Puukakai at an elevation of about 4500 feet. 
On Hawaii it has been found by Hillebrand in the dry district of Kawaihae- 
iuka, but could not be located during a visit made by the writer in that locality, 
though the writer was fortunate, however, to find it in the forests of Hilea in 
Kau, the most southern point on the Island of Hawaii, at an elevation of 2000 
feet. In this latter locality oceur the biggest trees of this species, while in the 
Kaiholena Mountains, elevation 4000 feet, of the same district, the trees are 
smaller and resemble the deseription (outward appearance) given by Mann of 
the trees which he found on Lanai. 
The wood of the Ohe ohe is rather soft and of no particular value. It is a 
hardy tree and can stand the ravages of cattle and other enemies better than any 
other Hawaiian tree.
