Polypodium quasidivaricatum Hayata, J. Coll. Sci. Imp. Univ. Tokyo 30: 446. 1911; Crypsinus intermedius (Ching) Tagawa; C. quasidivaricatus (Hayata) Copeland; Phymatodes intermedia Ching; P. quasidivaricata (Hayata) Ching; Phymatopsis intermedia (Ching) Ching; P. quasidivaricata (Hayata) H. Itô; Phymatopteris intermedia (Ching) Pichi Sermolli; P. quasidivaricata (Hayata) Pichi Sermolli; Pichisermollia quasidivaricata (Hayata) Fraser-Jenkins; Pichisermollodes quasidivaricata (Hayata) Fraser-Jenkins; Polypodium divaricatum Hayata (1909), not E. Fournier (1872); P. morianum C. Christensen.

Rhizome ca. 3 mm in diam., densely scaly throughout; scales castaneous at center, brown or light brown at margin, linear-lanceolate, ca. 5 × 1 mm, margin long ciliate, apex acuminate. Fronds monomorphic. Stipe straw-colored, 5-10 cm, glabrous; lamina pinnatisect, 10-20 × 5-15 cm, base cordate, margin notched or serrulate. Lateral lobes 2-5 pairs, lowest pair usually much deflexed, upper pairs spreading or ascending, linear-lanceolate, 5-7 × 1-1.5 cm, base slightly contracted, apex acuminate. Costa and lateral veins distinct on both surfaces, veinlets obscure. Lamina herbaceous, both surfaces glabrous. Sori orbicular, slightly near costa, superficial.

● Epiphytic on tree trunks or on rocks in forests; (1000-)2600-3200 m. Taiwan.

Selliguea quasidivaricata is very close to S. laciniata (Beddome) Hovenkamp, which is widely distributed from Thailand to New Guinea.

The name Phymatopteris quasidivaricata has been applied erroneously to a number of specimens from high mountains in Yunnan and possibly other provinces on the mainland. De Vol and C. M. Kuo (in H. L. Li et al., Fl. Taiwan 1: 177. 1975) misidentified material of this species as Crypsinus veitchii (Baker) Copeland.
