Durian 榴槤



There are about 30 known species of Durio. So far 9 species have been identified to produce edible fruits : D. zibethinus, D. dulcis, D. grandiflorus, D. graveolens, D. kutenensis, D. lowianus, D. macrantha, D. oxleyanus, D. testudinarum.

However, there are many species for which the fruit has never been collected or properly described and it is possible that other species with edible fruit exist.




Durio oxleyanus
Husk green. Spine slender & long. Flesh is yellow.



Durio kutejunsis
Husk yellow. Spine short. Flesh yellow, sticky, less sweet.


Durio zibethinus
Husk yellowish to green. Spine short. Flesh is white to yellow, sweet.

The name durian comes from the Malay word duri ( literally means thorn ), with a suffix -an for building a noun in Malay.
zibethinus refers to the Indian civet, Viverra zibetha.
There is disagreement regarding whether this name, refers to civets being so fond of the durian that the fruit was used as bait to entrap them, or to the durian smelling like the civet.
