Diagnostics:

Urophyllum hirsutum is a shrub or small tree about 3m tall. It is covered with dense white hairs on the twigs and lower surface of the leaves. A useful diagnostic is to search for its stipules found between the younger leaves (it will shed off eventually). It is hairy, long, and tapering to a point, with a raised ridge at the middle.


Interesting Facts:

This shrub can be found commonly in Bukit Timah and Central Catchment Nature Reserves, as well as the Singapore Botanic Gardens' Jungle (Keng, 1990; LaFrankie, 2005). The shrub is shade tolerant and can also be found along forest fringes.
