The longan (from Cantonese lùhng-ngáahn, literally 'dragon eye'), is so named because it resembles an eyeball when its fruit is shelled (the black seed shows through the translucent flesh like a pupil/iris).The seed is small, round and hard, and of an enamel-like, lacquered black.The fully ripened, freshly harvested fruit has a bark-like shell, thin, and firm, making the fruit easy to peel by squeezing the pulp out as if one were "cracking" a sunflower seed.When the shell has more moisture content and is more tender, the fruit becomes less convenient to shell.Depending upon climate and soil type the tree may grow to over 100 feet (30 m) in height, but it typically stands 30–40 ft (9–12 m) in height and the crown is round.The trunk is 2.5 ft (0.8 m) thick with corky bark.

The branches are long and thick, typically drooping.The leaves are oblong and blunt-tipped, usually 4–8 inches (10–20 cm) long and 2 in (5 cm) wide.The leaves are pinnately compounded and alternate.There are 6 to 9 pairs of leaflets per leaf and the upper surface is wavy and a dark, glossy-green.Gaab fruit plants in Keralais now available in our farms.
