The Keahi is a medium-sized milky tree with a roundish crown, and rough 
drooping branches. The leaves resemble somewhat those of the Sapota pear, or 
more so the Alaa (Sideroxylon sandwicense), and is hardly distinguishable from 
it when without fruit or flower. 
The flowers are borne all along the branchlets and very densely. It is a very 
prolifically bearing tree and can be found loaded with the black, olive-shaped 
shining fruits during the months of May to August. It inhabits the very dry 
regions on the leeward sides of most of the islands, and is very common on 
Lanai, where it grows in company with Siderorylon sandwicense, S. spathu- 
latum, the leaves of which look all very much alike and when not in fruit are 
exceedingly difficult to distinguish. On Molokai it is also common, as well as 
on the Island of Maui on the slopes of Haleakala, district of Kahikinui, while it 
has so far not been found on Hawaii. Together with Sideroxylon, Nothoces- 
trum, Suttonia, Osmanthus, Reynoldsia, Gardenia, Antidesma, Bobea Hookeri, 
and Rauwolfia, it forms the typical dry forest at the lower elevation on Mt. 
Haleakala, on the lava fields of Auahi. 
The Keahi is peculiar to the Hawaiian Islands. As far as can be ascertained, 
the natives made no use of this tree, though the wood is quite hard and durable, 
while the fruits are not edible.

A genus of over 100 species, occurring in the tropical and saueripiesl regions 
of the old and new world. In the Hawaiian Islands the genus is represented by 
several species usually growing in the dry districts on the lee sides on the various 
islands. Originally only two species were known from Hawaii, to which the 
writer had added two new ones. 
What has been said of the polymorphism of the genus Pittosp 
holds also good for the genus Sideroxylon. 
The tremendous variations which we find in the species growing in Hawaii 
make it indeed difficult to separate all these forms satisfactorily. The fruits 
of the Hawaiian Sideroxyla are of various shapes and colors, the largest fruits 
orum in Hawaii,
