Bouea, Mangifera and Spondias are classified under Anacardiaceae family in the order Sapindales. The
Anacardiaceae consists of trees, rarely shrubs or lianas, and often with turpentine smelling sap. There are about 70
genera with about 600 species, distributed chiefly throughout the tropics and subtropics. Malesia is the richest major
tropical area for this family [3]. There are 16 genera and 74 species indigenous to Malaysia, found from the
lowlands including swamps, to mountain forests. Certain species such as Glutacurtisii and Swintonia spp. appear to
grow gregariously in the hill and upper dipterocarp forests.
