Rhizome 3-7 mm thick (or more), internodes to 1-2.5 cm long; vascular strands with bundle sheath partially sclerified; sclerenchyma strands many to very many. Ground tissue very soft. Rhizome scales peltate, appressed to spreading, 5-9 by 2-3 mm, obtuse to mostly rounded, somewhat concave, sometimes acute, straw-coloured, with a lighter flabelloid margin, entire. Fronds simple, dimorphic. Fertile fronds with stipe 11-23 cm long; lamina 12-30 by 2.3-6.4 cm, index 3.9-6.7, widest at 0.2-0.4 from base. Sterile fronds with stipe 4.5-12 cm long; lamina 11-28 by 4.1-8.5 cm, index 2.2-3.3, widest at 0.3-0.4 from base. Venation: main veins distinct, on upper surface not raised or raised. Hydathodes frequent, calcareous scales not persistent. Margin cartilaginous, flat or thickened; notches absent, rarely regularly present, in fertile fronds absent. Sori round, rarely confluent within one areole, in two rows between adjacent veins, in 5 or more rows between costa and margin, 2-3 mm wide, superficial, but clearly marked on upper surface.
