Thelypteris adscendens Ching, Bull. Fan Mem. Inst. Biol., Bot. 6: 332. 1936.

Plants 25-50 cm tall. Rhizomes short, decumbent, with sparse short hairs and brown ovate-lanceolate scales. Fronds clustered or approximate; stipes 10-25 cm, stramineous, glabrous above bases; laminae 15-25 × 8-12 cm, ± tapering to bases, pinnate-pinnatifid, apices long acuminate and pinnatifid; pinnae 10-15 pairs, alternate, sessile, proximal 1 or 2 pairs ± shortened, bases slightly tapering; middle ones narrowly lanceolate, 4-6 × 1-1.5 cm, pinnatifid and reaching narrow wings on both sides of costae, long acuminate at apices, sometimes slightly caudate; segments 10-14 pairs, spreading, approximate, oblong-lanceolate, 4-6 × ca. 2.5 mm, entire or densely serrate in sinus along margins on proximal segments, rounded-obtuse at apices. Veins visible, veinlets usually forked on proximal segments, distal ones simple, 3-5 pairs per segment, proximal pair arising from slightly higher above base of costules, not reaching margins. Laminae herbaceous, when dry green, glabrous on both surfaces, only occasionally with sparse short hairs along both sides of costae. Sori small, orbicular, 2-4(or 5) pairs per segment, attached near ends of lateral veins, close to margins; indusia small, orbicular-reniform, membranous, green, or brownish when dry, glabrous or occasionally with several short hairs, usually deciduous when mature.
