Lansium domesticum Corrêa 'Langsat Group'

All names under the specific name apply to this group.


1. We realise (thank you for pointing it out) that we have placed some original "foreign" words such as "duku" which is strictly Malay / Indonesian into various languages. We avoid this as much as possible but sometimes plants that are popular in a restricted part of the globe tend to carry their original names with them. They then get corrupted (spelling changed) or transliterated / transcribed / romanised in various ways. In this case the words such as "duku" which are simple and easily read in most European languages do not get changed but are used in trading and casual conversation. There are also the legacies of the past illustrated for example by the Indonesian names used in Dutch such as "kokosan".

We took the opportunity to make these points because Lansium domesticum is a very good example of such plants.

2. We have been made aware that people from Indonesia (in its broadest sense) discriminate strongly between the golf-ball size duku fruit (native to Malaysia) and the large grape size langsat fruit (from a broader range in western Southeast Asia). The size of the fruit is not the only distinguishing mark but they tend to be overlooked given the many similarities of the plants. We have separated the 2 in our listing, guessing that group naming is the appropriate denomination... and added 2 other groups together with cultivars recognised by the Malaysian Department of Agriculture.
