The Olapa, as the tree is usually called on all the islands, reaches a height 
of 40 to 50 feet and sometimes more. It derives its name ‘‘Cheirodendron’’ from 
the Greek (Keiros—hand and Dendron—tree) on account of its leaves, which 
consist usually of five leaflets, giving it the shape of a hand. It is one of our 
most common forest trees, and is always conspicuous in the woods by its foliage, 
which is constantly in motion, even if there is hardly any breeze. Its trunk is 
Sometimes two feet and even more in diameter, and is vested in a smooth, yel- 
lowish bark when growing in wet forest, and rough, scaly bark in dry districts. 
All parts of this tree, as well as of the Lapalapa, emit a very strong carroty 
odor when bruised, not unlike turpentine, and the wood of both species is said 
to burn when green. Several varieties are recognized which are peculiar to cer- 
tain sections of the various islands, and are as follows :—
