Description:  "A medium sized to large tree, 15-25 m in height, with grey bark exfoliating in small irregular flakes. Leaves are simple, alternate, obovate oblong, rounded at the apex, coriaceous, glabrous above and more or less pubescent beneath, main nerves 15-25 pairs. Flowers are greenish white fascicled in pubescent panicles. Fruits are obliquely ovoid or oblong drupes and 2.5 cm long. The upper portion of the fruit is cup-shaped, smooth, fleshy, orange red in colour and sweet and edible when ripe. It is formed of the thickened disc and accerescent calyx base. The lower base, which may be termed the nut, consists of smooth, black, shining pericarp which is thick, containing between its outer and inner laminae oblong cells full of a corrosive resinous juice. This juice is white when the fruit is immature, but brownish or quite black when the fruit is ripe. The nut is approximately 1 x 0.75 x 0.33 inches and weighs on an average 3.5 g.  Inside the nut and protected by the hard shell is a white kernel which is sweet and nutritious as the almond or cashew-nut kernel"  (a href="http://www.cabdirect.org/abstracts/20083022681.html;jsessionid=0B3090774D564DC292E124BD71750A4B">Gouthaman et al., 2008; p. 194).
