Lansium domesticum

Lansibaum ( Lansium domesticum )

The Lansibaum ( Lansium domesticum ) is a plant from the family of the mahogany family ( Meliaceae ). He probably comes originally from Malaysia and is little known in Europe, but its fruits are in the Philippines, Thailand, Malaysia and Indonesia very popular and are also cultivated in South India and Sri Lanka.

Features

The Lansibaum is a slow-growing, medium-sized tree, which bears fruit and shade needed after 7 to 10 years. He attained stature heights of 10 to 15 meters, in culture usually only about 4 meters. The short-stemmed tree performs a resinous sap. The unpaired pinnate, 30-50 cm long leaves are opposite. The five or seven slightly leathery, up to 20 cm long, conspicuously veined leaflets are elliptic to obovate, pointed at both ends, hairy matt and different upper side glabrous and shiny and hand.

The small, predominantly hermaphroditic, white or pale yellow flowers grow to 30 cm long racemes or panicles, which ultimately depend, sometimes in groups, on the trunk or thick branches are first and with the development of the fruit. From an inflorescence to develop 6 to 20, sometimes up to 30 fruits.

The spherical, five to sechsklappige fruit capsule has a diameter of 2.5 to 3 cm, with succulent, glassy- white seed coats ( arils ) are filled; only one to three of which contain a complete seed (core). The seed coats usually taste sweet and sour; Specifically, the thin membrane that surrounds the core, and the core are very bitter in some varieties. The fruit, but also the bark of the tree, its leaves and the seed core can be used ( at least in Thailand) also for medical purposes.

In the south of Thailand and the province of Uttaradit is the read-out in Thailand variety Longkong ( Thai: ลองกอง, lO spoken: ng gO: ng) grown, which is very sweet and aromatic, without the sour proportion of normal fruit which Langsat ( Thai: ลางสาด spoken la: ng sà: d ) is called. In addition, the variety Longkong has few, sometimes even no nuclei, and is characterized by a thin shell with a little resinous sap.

System

The first description of the species by the Portuguese botanist José Francisco Corrêa da Serra was published in 1807.

Varieties

A total of 4 varieties are distinguished, which belong to the same species L. domesticum:

Thailand:

• Langsat: thin yellow / brown slightly hairy shell, slightly egg-shaped fruit with split green and very bitter core and milky excretion when the shell is broken
• Longkong (also Dongkong ): thicker yellow-brown rough shell, spherical fruit with several flattened bitter kernels, without milky excretion when the shell is broken
• Duku (L. var d domesticum ): thick pale yellow, hairy shell, round fruit with a spherical core

In Indonesia and Malaysia ( among other things on the island of Sumatra), the fruit is commonly referred to as Duku or Lanseh.

Philippines ( Lancones, also Lansones or Lanzones ): hard yellow-brown slightly textured shell, spherical fruit with split brown and very bitter core.

Use / use

Duku is on Java a popular fruit. The fruits are eaten fresh after removing the shell. The five to six white, glassy translucent segments can be easily detached from one another and taste pleasantly sweet and sour. The green seed is bitter. The variety Langsep tastes sour.

The wood is used in Java for building houses. Dried and ground bark is administered in dysentery and malaria as astringent tea.
