Durio singaporensis Ridl.
Family Name: | Malvaceae |
Synonyms: | Durio oblongus auct. non Mast.<2> |
Common Name: | Singapore Durian, Durian Duan |
Durio singaporensis is named after (you guessed it), Singapore! Commonly known as the Singapore Durian, its scientific name takes reference from the distribution of the species; within Singapore and Peninsular Malaysia. The Singapore Durian can grow up to 30 m tall producing thick leathery foliage with a golden-coppery underside. Unlike the Durian commonly eaten (Durio zibethinus), its fruit is densely covered in rambutan-like spines. The brown seeds also lack the yellow, pungent flavoured edible pulp that many enjoy.
