Fronds 50-80 cm; stipe amber, 18-42 cm, up to 1 cm in diam. at base, densely scaly; scales brown or reddish brown, ovate and linear, basal stipe scales dark brown at middle. Lamina bipinnate, narrowly ovate or narrowly oblong, 45-62 × 9-16 cm, rounded-cuneate, sometimes slightly contracted at base, acuminate; rachis without proliferous bulbils, densely scaly; scales reddish brown or brown, lanceolate with ciliate margins or linear, apex twisted. Pinnae 30-40 pairs, alternate, slightly ascendant, linear-lanceolate or broadly lanceolate, middle pairs 5-10 × 1.5-2 cm, obliquely cuneate to broadly cuneate, with stalk 1-2 mm, pinnate, acuminate. Pinnules 8-18 pairs, alternate, slightly ascendant, approximate, obliquely ovate, broadly ovate, or nearly rhombic, auricles deltoid, bases obliquely broadly cuneate, margins entire or with few spinulose teeth, apices acute or acuminate and spinulose; basal acroscopic pinnules largest, 1.2-1.6 cm × 5-6 mm, not divided or acroscopic margins pinnatilobate; abaxially scaly; microscales filiform, strongly ciliate at base; frond texture leathery; venation pinnate on pinnules, not concave or slightly raised abaxially, slightly concave adaxially.

A fern. It is herb. The frond stalk is erect. The plant is tufted. It is densely scaly. The axis that bears the leaflets is rust coloured with fine scales. The fronds are 5-70 cm long and oval to sword shaped. They are twice divided. There are many primary leaflets and the secondary leaflets are oblong and unequal at the base. They have an ear shaped projection on the upper side. There are small spines along the edge. The spore bodies are brown and in a single row on either side of the main vein.
It is a tropical plant. In Nepal it grows between 1000-3000 m altitude. In southern China it grows between 1,900-2,400 m above sea level.
