. . . . "Quassia (/\u02C8kw\u0252\u0283\u0259/ or /\u02C8kw\u0252\u0283i\u0259/) 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."@en . . . . .
