a2 GREENHEART. 
ironwood, or abelluello (Colubrina ferruginosa Brongn.), often called 
West Indian greenheart. The wood is strong and durable, but is - 
much inferior to the true greenheart. The tree from which this 
comes is comparatively small, seldom over 75 feet high, and 2 feet 
in diameter, even in Martinique, where it attains its best development. 
Owing to its small size, the substitution of this wood for true green- 
heart must necessarily be very limited. Another species of this 
genus, Colubrina reclinata Brongn., a relatively low tree, seldom 
over 60 feet high, found in the mountains of Cuba, yields a strong 
and durable wood sometimes referred to as greenheart. The green- 
heart of Jamaica (also called cogwood or cerillo) is the Ceanothus 
chloroxylon Nees. It is a small tree and does not enter into com- 
petition with the genuine greenheart. Still another tree from 
Jamaica sometimes called greenheart is Zizyphus chloro«ylon Oliver. 
it is of good size throughout the mterior hills, though not plentiful. © 
The wood is dark, close grained, and weighs about 70 pounds per 
cubic foot. 
Greenheart is the name applied also to a Jamaican tree, Sloanea 
jamaicensis Hook., which grows from 70 to 100 feet in height, with 
a trunk about 2 feet in diameter. It is confined largely to the in- 
terior of the island, where it attains its largest sizes in the limestone 
soil. The wood is very hard, heavy, fine grained, dark colored, and 
is suitable for a good many purposes. It 1s said to be very durable 
in contact with the soil.
