Lax and pendulous, or sometimes recurved from an erect and somewhat rigid stem base, up to 50–70 cm long. Shoots usually gradually tapering from ca. 20–30 mm in diameter incl. leaves at the base, to (3–) 4–7 mm in diam. in terminal, densely sporangiate divisions of fully developed plants, sporangiate from 10–50 cm above the base and upward, sometimes not, or only slightly tapering (juvenile or tardily sporangiate individuals), rarely abruptly constricted. Stems excluding leaves 1.5–3 mm thick at the base, tapering to 1–1.5 mm upward, somewhat ridged by decurrent leaf bases, pale greenish to brownish, usually 4–5 (–7) times dichotomous. Leaves usually reduced and modified upward, borne in alternating whorls or irregular low spirals of 3 or 4, these 1.5–4 mm apart, forming 6–8 indistinct longitudinal ranks. Leaves of basal divisions spreading to ascending or somewhat appressed, often twisting the lamina to a vertical position from the leaf base, narrowly lanceolate, broadest in the lower half, broadly joined to the stem, firmly herbaceous to subcoriaceous, 14–23 × (1.5–) 2–3.5 mm, almost flat or somewhat concave adaxially, with flat or slightly revolute, smooth margins, with evident to somewhat prominent vein abaxially. Leaves of middle and terminal divisions usually gradually shorter, narrower and more appressed, abaxially more convex, with involute margins. Leaves of fully sporangiate divisions often distinctly 6-ranked, with strongly broadened, clasping base, partly covering the sporangia, often abruptly contracted into a short to long, narrow, involute apex, 3–8 mm long, 1–1.5(–2) mm wide. Sporangia 1–1.5 mm wide.

­­­ Distribution:— Central America, West Indies, northern South America, south to Bolivia and Brazil (Paranaì).

­­­ Habitats:— Epiphytic in lower to mid-elevation wet montane forest, elev. 100–3000 m elev.

Notes:— As showed by the number of synonyms Phlegmariurus taxifolius is a variable species. Intermediates between P. taxifolius , P. tubulosus , P. linifolius , and P. homocarpus are frequent. Phlegmariurus oellgaardii , which differs by its larger size, large basal leaves, large sporophylls (6–10 × 2–2.5 mm) in whorls of 4, and sporangia 2–3 mm wide, is closely related to P. taxifolius and sometimes considered conspecific. It is currently only known from Costa Rica but it should be looked for in Panamá.
