Notes
The limestone Bornean form is abundant in the Gunong Mulu National Park; at higher altitudes and in more exposed positions fronds are smaller and very densely covered with hairs on the upper surface, but there seems to be no sharp distinction between these and plants with larger fronds less densely covered with hairs.
