Lansium domesticum

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 hermaphrodite, having both stamen and pistil structures in the same flower. The pale-yellow, fleshy flowers are found in inflorescences of around thirty blossoms, 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 along the branches and trunk. 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 fruit taste has been compared to a combination grape and "perfect" grapefruit with no bitterness. Yet the seeds if bitten have the bitterness of a grapefruit yet stronger. The sweet juicy flesh contains sucrose, fructose, and glucose.

Ecology and life history
It grows wild in Sumatra forests where a wide and longest river in Indonesia lay across the southern part of Sumatra. The river rises and floods the forest lands for a few months, when it subsides, the flood leaves plenty of fallen leaves and twigs enriching and moistening a large area of the forest bed, resulting in ideal conditions for the plant to grow naturally. Local people will come and harvest it as natural forest produce. They climb up the tree with ripe fruits (after observing it), holding with their hands on the smaller branches and shaking it. Mature fruits will fall easily down to the ground. They will then collect it and transport it on a small boat on a nearby river to the villages and sell it. In a good year a 20-year old tree can produce 100 kg of fruits, however fruiting is often uneven.
