    Species Description - Plants pendent, flaccid, 13-40 cm long, 2-5 times forked; stems 0.5-1.2 mm diam. (without leaves), stramineous to light brown; leaves spreading to oblique (somewhat ascending), distant, mostly 1-2 mm apart, spiral in few (4-6) ranks, twisted (with branches appearing somewhat flattened), linear-lanceolate, narrowed to base or short-petiolate, straight or usually subfalcate, usually pale or yellowish green, papyraceous to chartaceous, entire, midvein prominent abaxially, leaves near base of plant 1.5-2.5 cm long, 2.0-3.0 mm wide about ¼ length of leaf, abruptly narrowed to 0.5 mm base, smaller toward tip of stem, 1.0-2.0 cm long, 1.0 mm wide above narrowed base; sporophylls similar to vegetative leaves but slightly smaller.

    Urostachys linifolius (Linnaeus) Herter, Repert. Spec. Nov. Regni Veg. 19: 165. 1923. Huperzia linifolia (Linnaeus) Trevisan, Atti Soc. Ital. Sci. Nat. 17:248. 1874 [1875]. Lectotype (chosen by Proctor, FI. L. Antill. 2: 26. 1977). Plunder, Traité foug. Amér., t. 166, f. C. 1705, illustrating a plant from Martinique or Hispaniola. Oaxacan material of this species is fairly uniform. Nessel’s varieties (1939) are not distinct enough to be used with confidence. Narrowed leaf bases and leaves not in pseudowhorls distinguish this species from slender specimens of the L. taxifolium alliance.
