Chrysobalanææ

Chrysobalanææ, a sub-order of Rosaceæ (q.v.), presenting close affinities through Cæsalpineæ to Leguminosæ. The 180 species are trees or shrubs, natives of tropical and subtropical America and Africa. The fruit of many is eatable, as the Cocoa Plum of the West Indies (Chrysobalanus). The kernels of some resemble sweet-almonds, notably those of Acia dulcis, and other species of Guiana. A useful oil is expressed from the seeds of Prinsepia utilis, a spiny Himalayan plant.
