Rhizome 4-5 mm thick, internodes to 1.5-4 cm long; vascular strands with bundle sheath fully sclerified to sclerified, 2 cells thick; sclerenchyma strands very many. Rhizome scales peltate, appressed, 5-9.5 by 2.3-3 mm, obtuse, straw-coloured to brown, with a lighter flabelloid margin, entire. Fronds simple, dimorphic. Fertile fronds with stipe 1-12 cm long; lamina 9-21 by 1.4-3.1 cm, index 3-7.9, widest at 0.2-0.5 from base. Sterile fronds with stipe 2-8.5 cm long; lamina 12-21 by 2.4-4.7 cm, index 1.8-5.2, widest at 0.3-0.5 from base. Venation: main veins on upper surface raised, distinct. Hydathodes absent. Margin not differentiated to cartilaginous, flat to thickened; notches sporadically to regularly present. Sori round, elongate or confluent to coenosorus, confluent across connecting veins (occasionally confluent within one areole), in one row between adjacent main veins (occasionally in 2 rows), in 5 or more rows between costa and margin, 2-4 mm wide, slightly sunken.
