Tectaria palmata var. dimorpha

Distribution

Asia-Tropical: Borneo present
Malesia: Borneo (known only from the type locality).

Morphology

The indusia of var. dimorpha are rather smaller than those on specimens of var. palmata and have papillae on the upper surface as well as on the margins; the sori are close together on the contracted lamina.

In both var. platanifolia and var. dimorpha a scaly bud is someti mes present at the base of the lamina, on the upper surface of the costa; such buds have not been seen in var. palmata.
