Trichilia triacantha

Trichilia triacantha, the bariaco, is a species of plant in the Meliaceae family endemic to Puerto Rico.

Description
The bariaco is a shrub or a tree reaching up to 9 meters tall. It has leaves made up of several leathery, spine-toothed leaflets and the flowers are white. The fruit is a capsule with a red aril.

Habitat
The plant grows in dry forest habitat on limestone substrates, often near intermittent streams.

Conservation
As of 2007 there were 10 populations of the tree containing a total of 109 individuals. 47 of these were found to be fertile. Six of the ten populations were located in the Guánica National Forest. Two of these were composed of single individuals located several kilometers from other members of the species, and so are unlikely to reproduce.

This plant has been overharvested because its wood is useful and attractive. It is additionally threatened by habitat loss, and as such is a federally listed endangered species of the United States.
