= Lycopodium filiforme Sw., J. Bot. (Schrader) 1800 (2): 114. 1801.

= Huperzia filiformis (Sw.) Holub, Folia Geobot. Phytotax. 20: 72. 1985.

Range: —Central America; Andes from Venezuela to Bolivia (SC); Hawaiian Islands ( Wagner et al. 1995).

Ecology: —Rare; epiphytic in montane forests; 3200 m, 1000–2900 m elsewhere.

Notes: — Phlegmariurus filiformis is closely related to P. acerosus , and their delimitation is problematic. The former appears to grow under slightly drier conditions than P. acerosus . The elevation given is based on a single, mixed collection by Steinbach, and is higher than otherwise recorded for the species. The type is from the Hawaiian Islands.
