Durian
!Durian fruit cut open to show the edible flesh
Description
D. zibethinus is the only species commercially cultivated on a large scale and available outside its native region. Since this species is open-pollinated, it shows considerable diversity in fruit colour and odour, size of flesh and seed, and tree phenology. In the species name, zibethinus refers to the Indian civet, Viverra zibetha. There is disagreement over whether this name, bestowed by Linnaeus, alludes to civets being so fond of the durian that the fruit was used as bait to entrap them, or to the durian's smelling like the civet.
Description
Durian flowers are large and feathery, with copious nectar); they give off a heavy, sour, buttery odour. These features are typical of flowers pollinated by certain species of bats that eat nectar and pollen. Durians can be pollinated by bats (the cave nectar bat Eonycteris spelaea, the lesser short-nosed fruit bat Cynopterus brachyotis, and the large flying fox, Pteropus vampyrus). Two species, D. grandiflorus and D. oblongus, are pollinated by spiderhunter birds (Nectariniidae), while D. kutejensis is pollinated by giant honey bees and birds as well as by bats. Some scientists have hypothesised that the development of monothecate anthers and larger flowers (compared with those of the remaining genera in Durioneae) in the clade consisting of Durio, Boschia, and Cullenia was in conjunction with a transition from beetle pollination to vertebrate pollination.
