Rhizome 1.5-2.5 mm thick, internodes to 0.2-0.5 cm long. Vascular strands with bundle sheath hyaline or partially sclerified. Sclerenchyma strands many. Rhizome scales peltate, spreading to slightly squarrose, 7.5-8.5 by 1 mm, acute or slightly contracted to a narrow acumen, brown, evenly coloured, entire or remotely and weakly dentate. Fronds simple, mono-to dimorphic. Fertile fronds with stipe 2-10 cm long; lamina 17-34 by 0.7-1.3 cm, widest at 0.5-0.8 from base. Sterile fronds with stipe 1.5-5 cm long; lamina 10-21 by 1.6-2.2 cm, index 5.5-8.1, widest at 0.5-0.8 from base; base very gradually narrowed. Venation: costa distinct, with two very distinct ridges on upper surface, main veins sometimes distinct, not raised on upper surface. Hydathodes absent. Margin not differentiated or cartilaginous, thickened; notches sporadically to regularly present. Sori round, in two rows between adjacent veins, in 2-4 rows between costa and margin, 1.5-3 mm wide, superficial to slightly sunken.
