Rhizome creeping, 6-8 mm in diameter; rhizome scales up to 5 mm long, appressed, reddish-brown, narrowly lanceolate. Fronds spaced apart, erect or arching, coriaceous, simple, dimorphous. Sterile frond: stipe stramineous, with scattered brown scales when young, up to 18 cm long; lamina up to 33 × 5 cm, narrowly elliptic-oblong in outline, apex rounded, base wedge-shaped, margin with a pale inrolled edge, subglabrous with minute brown scales below. Fertile frond: stipe much longer than that of the sterile frond, lamina shorter and narrower (up to 6 × 1.8 cm) than sterile lamina, sori covering the whole undersurface of the lamina. |
Notes: | The rounded apex of the frond distinguishes this fern from other similar species. |
