The tall narrowed frond is in general habit somewhat like H. Zol- 
lingerianum as figured by Van den Bosch (Hymen. Javan. t. 50), and bears 
about 20 pinnew on each side. In the dried specimens the frond-apex is 
cernuous and the pinne complicato-decurved. The narrowly winged stipes 
and rhachis, the flat serrulate ultimate segments, the narrowly dentato-cristate 
custules, and the hairiness of stipes, rhachis, coste, and costules are characters 
to be noted.
