Guarea F. Allam. ex L.

Guarea is a genus of evergreen trees in the mahogany family Meliaceae, native to tropical Africa and Central and South America. They are large trees 20–45 m tall, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet present. The flowers are produced in loose inflorescences, each flower small, with 4-5 yellowish petals. The fruit is a four or five-valved capsule, containing several seeds, each surrounded by a yellow-orange fleshy aril; the seeds are dispersed by hornbills and monkeys which eat the fleshy aril.

Uses

The timber is important; the African species are known as Bossé, Guarea, or Pink Mahogany, and the South American species as Cramantee or American Muskwood. It is said to possibly cause hallucinations if ingested.^[1]

The bark of Guarea rusbyi (Britton) Rusby, a synonym of Guarea guidonia (L.) Sleumer,^[2] is used as an expectorant^[3] named cocillana.^[4]
