Semecarpus anacardium L.f.

Vernacular names Marking-nut tree, oriental cashew nut (En). Thailand: rakkhon (Kanchanaburi).

Distribution Originating from India, now also cultivated in Africa, Australia, and occasionally in South-East Asia.

Uses The swollen pedicel looks like a fruit and is eaten after roasting; the kernel may be eaten, but needs careful shelling. Juice from the false fruit, mixed with lime water, gives a black marking ink. The nuts are used in tanning, the false fruits in dyeing. The pericarp contains about 9% of an irritating oil which is used in traditional medicine, but also in industry (in lacquers, paints, insulating material). The wood is used as charcoal.

Observations Tree, up to 15 m tall. Leaves simple. Flowers unisexual, seldom bisexual, greenish. Fruit a globose-ovoid drupe, reniform, 2 cm x 2.5 cm, black; hypocarp fleshy, equal to drupe. On hill slopes, usually between 500—1000 m altitude. In India flowering in May—July, fruiting in March.
