Description : Rhizome short, erect, scaly. Stipe dark stramineous, densely scaly; scales nearly black, linear, about 20 by 1.2 mm. Lamina oblong with acuminate apex, bipinnate or tripinnatifid in lower part, about 35 by 25 cm; lower 5–6 pairs of lateral pinnae similar to each other in size, oblong-lanceolate with caudate-acuminate apex and broadly cuneate base, 10–13 by 5 cm, with stalks 3–10 mm long; upper pinnae rather suddenly becoming smaller, sessile to adnate at base, pinnatifid to subentire; pinna-rachis densely covered with bullate scales brown with dark brown tails; pinnules patent or slightly ascending, oblong-subdeltoid, round to moderately acute at apex, cordate and shortly stalked or broadly cuneate and sessile or adnate in smaller ones, slightly auricled on both bases, pinnatisect at basal part of larger ones, up to 3 by 1 cm, lobes gradually shallower upwards; papyraceous, green. Sori dorsal on veinlets, medial or a little nearer margin, scattered from basal middle portion of frond; indusia round-reniform, about 0.7 mm diam., glabrous.

Thailand : NORTHERN: Tak (Mae Sot), Phitsanulok (Salaeng Haeng); CENTRAL: Nakhon Nayok (Khao Yai); SOUTH-EASTERN: Chanthaburi (Khao Soi Dao).

Distribution : S China (type), N Vietnam.

Ecology : On rather dry ground along streams in light shade at about 800–2,000 m alt.

Notes: The type specimen is of an imperfect frond, though the identification is not in doubt. The stipe and rachis are nearly naked in fully matured plants, but the scars of the fallen scales show that the scales were dense there. Tardieu & C. Christensen (1941) give a description and figure of this species in which the stipe and rachis are without scales, which may represent old material.
