Meniscium cuspidatum Blume, Enum. Pl. Javae 2: 114. 1828; Abacopteris cuspidata (Blume) Ching; A. liukiuensis (Christ ex Matsumura) Tagawa; Cyclosorus cuspidatus (Blume) Copeland; C. liukiuensis (Christ ex Matsumura) Masamune; Dryopteris cuspidata (Blume) Christ; D. liukiuense (Christ ex Matsumura) C. Christensen; M. liukiuense Christ ex Matsumura; Nephrodium clavivenum Yabe ex Matsumura & Hayata; Phegopteris cuspidata (Blume) Mettenius; Thelypteris liukiuensis (Christ ex Matsumura) K. Iwatsuki.

Plants ca. 1 m tall. Rhizomes short and decumbent, with dark brown scales; scales lanceolate, sparsely shortly hairy. Fronds approximate; stipes 15-35 cm, bases with dark brown scales and hooked hairs, distally glabrous; laminae ovate, 25-30 cm, 1-imparipinnate; lateral pinnae 2-4 pairs, oblanceolate, 8-14 × 2-3.5 cm, cuneate or narrowly rounded at bases, shortly stalked, usually with a gemma in axil, entire or undulate-crenate at margins, caudate-acuminate at apices; terminal pinna larger than lateral ones. Laminae papery when dry, brown and tinged scarlet. Veinlets obvious, 6-8 pairs regularly joining into areoles, excurrent veinlets usually not reaching next pair of joined veins. Sori orbicular or elongate, attached on middle of veinlets, usually confluent and spreading throughout pinna surface, exindusiate.

Knapp (Ferns Fern Allies Taiwan, 444. 2011) does not treat Cyclosorus cuspidatus and C. liukiuensis as conspecific, accepting only C. liukiuensis for Taiwan. Dryopteris cuspidata var. epigea Copeland (Philipp. J. Sci. 3: 278. 1908), described from Guangdong (Tai Mo Shan), may belong here.
