Santalaceae. 
In the Hawaiian Islands four species are to be found, which are perhaps only 
variations of a single species. Since the large export of Sandalwood from these 
Islands to China, the trees have became rather scarce and only individual ones 
can be found scattered through the drier forests. On Oahu, Sandalwood trees 
or Iliahi are still plentiful in certain districts, such as Kahuku, and in Palolo 
Valley, where they are very numerous at the lower elevation in company with 
Acacia Koa (Koa).

Santalum Freycinetianum, the Hawaiian Sandalwood of the commerce of by- 
gone days, is a most variable species. It is often a small shrub, but usually a 
medium-sized tree, and is peculiar to the dry regions of these Islands. It loves the 
lava fields of the Island of Hawaii, where it is especially common, comparatively 
speaking. It occurs as a small tree in South Kona on the lava fields of Kapua, 
and Manuka, while in North Kona on the old lava flows of Mt. Hualalai it 
reaches a handsome size. Here the tree grows 35 feet or so tall, with a trunk of 
10 to 12 inches in diameter, which is clothed in a rather rough sealy bark. 
On the slopes of Mauna Loa above Kealakekua, at an elevation of about 5000 
feet, the writer met with the biggest Sandalwood trees to be found in the whole 
group. They differ very much in their outward appearance from the other varie- 
ties known to the writer. The trees reach a height of over 50 feet and have a
