'''''Lansium domesticum''''' is a species of fruit-bearing [[tree]] belonging to the family [[Meliaceae]].
==Anatomy, morphology and habit==
===Habit===
''Lansium domesticum'' is a medium-sized, single-trunked tree that usually grows from ten to fifteen meters tall.<ref name="Morton1987">{{cite book | last =Morton | first =Julia F. | authorlink =Julia Morton | title =Fruits of warm climates | publisher = Florida Flair Books | date =1987 | location =Miami, FL. | pages =p. 201–203 | url =http://www.hort.purdue.edu/newcrop/morton/langsat.html | doi = | id = | isbn = 0961018410 }}</ref>
The plant has [[pinnate|pinnately compound]] [[leaf|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.<ref name="Morton1987"/>
===Flowers===
''L. domesticum'' [[flower]]s are [[bisexual]], having both [[stamen]] and [[pistil]] structures in the same flower. The pale-yellow, fleshy flowers are found in [[inflorescence]]s or around thirty, in most cases in a [[raceme]] usually around thirty centimeters long.<ref name="Morton1987"/>
===Fruit===
[[Fruit]]s are [[ovoid]], roundish [[orb]]s 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.<ref name="Morton1987"/>
==Distribution==
{{sectstub}}
''Lansium domesticum'' was originally native to the [[Malaysia|Malaysian]] [[peninsula]].
Agriculturally, the tree is grown throughout the entire [[Southeast asia|Southeast asian]] region, ranging from Southern [[India]] to the [[Philippines]] for its fruit. In the Philippines, the plant is grown mostly on the northern island of [[Luzon]] due to the species' narrow range of conditions favorable to its survival. Within mainland [[Asia]], the tree is cultivated in [[Thailand]], [[Vietnam]] and [[India]], as well as its native Malaysia. Outside the region, it has also been successfully transplanted and introduced to [[Hawaii]] and [[Surinam]].<ref name="Morton1987"/>
