Fronds 40-50 cm; stipe stramineous, 15-18 cm, 3-4 mm in diam. at base, densely scaly; scales reddish brown, ovate and lanceolate, margins toothed. Lamina 1-pinnate, linear-lanceolate, 34-42 × 5-5.5 cm, base nearly truncate, apex acuminate; rachis without proliferous bulbils, abaxially densely scaly in lower part; scales reddish brown, ovate, gradually becoming lanceolate and linear upward, toothed. Pinnae 30-34 pairs, attached at right angles to rachis, shortly stalked, ± approximate, oblong, middle pinnae 2.4-2.8 × 1-1.2 cm, bases obliquely broadly cuneate, acroscopic bases auriculate, margins spinulose-toothed, apices rounded, or slightly contracted to obtuse and mucronate; abaxially with dense microscales; microscales reddish brown, filiform; frond texture hard leathery; venation pinnate, lateral veins twice-forked, slightly concave abaxially, indistinct adaxially.
