Rhizome 2 mm thick, internodes to 0.4-0.8 cm long; vascular strands with bundle sheath hyaline; sclerenchyma strands few. Rhizome scales pseudopeltate, spreading, 4-5.5 by 0.6 mm, acute, straw-coloured, or brown; acumen dull light-brown; base darker; margin remotely and weakly dentate at base, entire in acumen. Fronds simple, strongly dimorphic. Fertile fronds with stipe 5.5-11 cm long; lamina 3-8 by 0.2-0.3 cm, linear. Sterile fronds with stipe 0.3-2 cm long; lamina 1-2.5 by 1-1.7 cm, index 1-2.1, widest at 0.3-0.5 from base. Venation: costa only distinct; veinlets anastomosing, free veinlets excurrent and recurrent. Hydathodes absent. Margin cartilaginous, thickened to strongly thickened; without notches. Sori confluent across veins into a longitudinally elongated coenosorus, a single one between costa and margin, superficial.
