= Huperzia linifolia (L.) Trevis., Atti Soc. Ital. Sci. Nat. 17: 248. 1874.

Range: —Central America; Antilles; northern South America south to Bolivia (BE, CO, LP, SC).

Ecology: —Epiphytic in lowland and mid-elevation humid forests; 0–3000 m.

Notes: —A variable species (grading into P. taxifolius ) with four varieties usually recognized in tropical America. The following two are known from Bolivia:

1 Shortest sporangiate leaves of densely sporangiate divisions usually conform to leaves of basal divisions, or shorter, each usually with a twisted, narrow to slightly broadened laminar base, perpendicular to spreading-ascending, pale, transparently green or brownish green; stems, at least in terminal divisions, usually transparently stramineous to reddish brown, the vascular tissue usually visible through the cortex................................................................................................................................... var. jenmanii

– Shortest sporangiate leaves of densely sporangiate divisions with distinctly broadened, usually untwisted laminar bases, usually ascending to loosely appressed, opaquely green; stems usually opaque-stramineous ............................................... var. tenuifolius var. jenmanii (Underw. & F.E.Lloyd) B.Øllg., Rodriguésia 63: 480. 2012.

= Huperzia jenmanii (Underw. & F.E.Lloyd) Holub, Folia Geobot. Phytotax. 20: 74. 1985.

= Huperzia linifolia var. jenmanii (Underw. & F.E.Lloyd) B.Øllg. & P.G.Windisch, Bradea 5: 13. 1987.

Range: —Throughout the Amazonian lowland region, from the Guianas and northern coastal Brazil to Bolivia (LP, SC).

Ecology: —Uncommon; lowland and riverine forests; 100–1000 m.

var. tenuifolius (Nessel) B.Øllg., Phytotaxa 57: 16. 2012. ( Fig. 16B )

= Huperzia linifolia var. tenuifolia (Nessel) B.Øllg., Fl. Ecuador 33: 90. 1988.

Range:— Northern Andes and eastern Andean slope of Ecuador south to Bolivia (BE, CO, LP).

Ecology:— Fairly common; humid montane forests; 950–2500 m.
