Abstract
Longan (Dimocarpus longan Lour.) belongs to Sapindaceae family, and is one of the important tropical/subtropical woody fruit trees. The number of chromosomes is 2n=2x=30. Longan trees are usually 6–10 meters tall, however, many grow in wilderness up to 40 meters with a trunk diameter of up to one meter. Sometimes trees are with buttresses, branches terete occasionally with warty lenticles, densely tomentose; and leaves are normally glabrous, sometimes hairy. Fruit are drupaceous, 1–3 cm in diameter, ellipsoid to globular, smooth to warty, sometimes granular, yellow-brown. Seeds are globular, with shining black or brown testa, and the seed are enveloped by a fleshy white arilloid (Tindall 1995, quoting from Verheij & Cornel 1991).
