Diagnostics:

Agrostistachys borneensis is a very common short tree found in the understorey of Bukit Timah and Central Catchment Nature Reserves. The form is very distinct, being short (normally below 3 meters), lacking branches, and with large leaves densely arranged in a rosette near the apex.


Interesting Facts:

The common name Leaf Litter Plant arises from its ability to collect falling dead leaves within its cluster of leaves. Upon decomposition of the dead matter, the plant is able to absorb nutrients directly from small rootlets that grow out from the base of the leaves (Wang et al., 2012). This strategy helps it to be self-sufficient rather than competing for nutrients with other plants on the forest soil.
