Physical description: The family Simaroubaceae (or Simarubaceae) consists of about 25 genera and 150 species of tropical trees and shrubs closely allied to the Meliaceae, Rutaceae and Burseraceae. Simaroubaceae are known to abound with a series of complex oxygenated triterpenoids known as quassinoids and limonoids, ß-carboline alkaloids and furanocoumarins. Simaroubaceae are, like Meliaceae, easily recognizable in field studies by their the leaves which are compound, elongated, spiral, without stipules and crowded at the apex of the bole, which is regularly marked with round scars. The inflorescences are axillary or terminal racemes of tiny, regular, hypogy-nous, often unisexual, and 3-8-merous flowers. The calyx includes 5 sepals which are connate towards the base. The corolla comprises of 5 petals which are free petals, imbricate or valvate. The andrecium comprises of 10 stamens, arranged in 2 whorls and inserted at the base of a well-developed nectary disc. The gynecium consists of 2-5 carpels united into a plurilocular ovary, with each locule containing a single ovule attached to axil placentas. Each carpel develops upward into 1-5 styles. The fruits are capsular or samaras or occasionally drupes or berries.
