Rhizome scales peltate, spreading, 1.4-2.8 by 0.4-0.6 mm, acute, brown, evenly coloured, strongly dentate. Fronds simple, mono-to dimorphic. Fertile fronds with stipe (1-)2.5-3.5(-6.5) cm long; lamina 2-7 by 0.3-0.8 cm, index 4-17, widest at 0.4-0.9 from base or linear. Sterile fronds with stipe 0.5-3.5 cm long; lamina 1.3-4 by 0.7-1.7 cm, index 1.6-5, widest at 0.4-0.7 from base or linear; apex rounded. Venation: costa only distinct; veinlets anastomosing, free veinlets excurrent and recurrent. Hydathodes absent.
