Lycopodium cryptomerianum Maximowicz, Bull. Acad. Imp. Sci. Saint-Pétersbourg 15: 231. 1870; Huperzia cryptomeriana (Maximowicz) R. D. Dixit; Urostachys coreanus (Herter ex Nessel) Herter; U. cryptomerianus (Maximowicz) Herter ex Nessel; U. cryptomerianus var. coreanus Herter ex Nessel.

Lycophytes, medium-sized. Stems caespitose, mature branches erect or slightly pendulous, 1-4 times dichotomously branched, 20-25 cm, stem together with leaves 2.5-3 cm wide at middle. Leaves spreading. Trophophylls sparse, lustrous, lanceolate, 1.4-2.5 cm × 1.5-2.5 mm, thinly leathery, midrib raised abaxially and distinct, base cuneate, decurrent, sessile, margin entire, apex acute. Strobili slightly thinner than sterile part, terminal on branches. Sporophylls lanceolate, 1-2 cm × ca. 1.5 mm, base cuneate, margin entire, apex acute. Sporangia yellowish, reniform, vertically bisected.

Epiphytic on tree trunks or on rocks in forests, or terrestrial; 400-800 m. Taiwan, Zhejiang [Japan, Korea, Philippines].

Phlegmariurus cryptomerianus has been widely misidentified in China as P. pulcherrimus.

This species was previously transferred from Lycopodium to Phlegmariurus in Fl. Anhui (1: 21. 1985) and Fl. Zhejiang (1: 3. 1993), but those combinations were not validly published because the basionym was not indicated (Melbourne Code, Art. 41.5).

This species is similar to Phlegmariurus mingcheensis, but the texture of its leaves is slightly thicker and its midrib is raised abaxially.
