Duku - Lansium domesticum

Lansium domesticum is a species of fruit-bearing tree belonging to the family Meliaceae.
Lansium domesticum is a medium-sized, single-trunked tree that usually grows from ten to fifteen meters tall.

The plant has pinnately compound leaves that grow to a length of around twenty to fifty centimeters long per leaf. Each fully-grown leaf has five to seven slightly-leathery, obovate leaflets that can reach a length of twenty centimeters each. A very prominent midrib bisects each dark green, glossy leaflet.
L. domesticum flowers are bisexual, having both stamen and pistil structures in the same flower. The pale-yellow, fleshy flowers are found in inflorescences or around thirty, in most cases in a raceme usually around thirty centimeters long.

Fruits are ovoid, roundish orbs around five centimeters in diameter, usually found in clusters of two to thirty fruits. Each round fruit is covered by yellowish, thick, leathery skin. Underneath the skin, the fruit is divided into five or six slices of translucent, juicy flesh. The flesh is slightly acidic in taste, although ripe specimens are sweeter. Green, seeds are present in around half of the segments, usually taking up a small portion of the segment although some seeds take up the entire segment's volume. In contrast with the sweet-sour flavor of the fruit's flesh, the seeds are extremely bitter.The sweet juicy flesh contains sucrose, saccharose, fructose and glucose
