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

Range: — U.S.A. (Florida); Antilles ; Central America ; northern South America south to Ecuador (including Galápagos Islands), Amazonian Bolivia ( LP, SC), and Brazil (Acre, Mato Grosso, Ceará) ; 0–1500 m.

Ecology: —Uncommon; epiphytic in humid lowland and lower montane forests; 300–1500 m.

Notes: —Plants usually rather short and recurved to pendulous, with linear, densely crowded, usually basally twisted, falcately ascending leaves. Closer study of the material referred to this species may show the presence of more than one taxon, especially in the northern part of the range, due to considerable variation in the thickness of stems, leaf length and direction, and compactness of the plants. However, the correlation of the variation with growth conditions is unknown.
