Rhizome 1.5-2 mm in diam., densely scaly throughout; scales brown or dark brown at peltate base, ovate-lanceolate, margin sparsely ciliate, apex acuminate. Fronds monomorphic. Stipe straw-colored or dark stramineous, 2-5 cm, slender, glabrous; lamina pinnatisect, 5-10 × 5-7 cm, base truncate or shallowly cordate, margin shallowly serrate. Lateral lobes 2-5 pairs, lowest pair slightly deflexed at base, 2-3 × ca. 1 cm, base usually contracted, apex obtuse or acute.

Crypsinus veitchii (Baker) Copeland from Japan and Korea is closely related to Selliguea senanensis, but the lamina lacks the deflexed basal lobes (Iwatsuki, Fl. Japan, as Crypsinus veitchii, http://foj.c.; accessed 4 Feb 2012).
