EOL Text
A single population, now thought to be extinct, was once recorded from El Sabalo in Pinar del Ro Province, Cuba, where the habitat has largely been deforested. Elsewhere in the Greater Antilles, the species and habitat have also suffered from overcutting. A record exists from northern Venezuela.

Quassia (/ˈkwɒʃə/ or /ˈkwɒʃiə/) is a flora genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, Quassia amara from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs. The genus was named after a former slave from Surinam, Graman Quassi in the eighteenth century. He discovered the medicinal properties of the bark of Quassia amara.
Broader treatments of the genus include the following and other species:
- Quassia africana
- Quassia amara
- Quassia arnhemensis Craven & Dunlop- Australia
- Quassia bidwillii
- Quassia indica
- Quassia sp. 'Moonee Creek' - Australia
- Quassia sp. 'Mount Nardi' - Australia
- Quassia undulata
It is the source of the quassinoids quassin and neo-quassin.[1]
