Description

Epiphytic or lithophytic plants. Branches tufted, pendulous or erect, but arched to nodding distally, undivided or 1–several times branched, 30–75 cm long; sterile portion (including leaves) 1.5–3 cm diam. Leaves subwhorled to spirally arranged, thin, firm, angled at 60–90° to axis, twisted near base, linear-lanceolate, attenuate, entire, 10–20 mm long, 1–2 mm wide, pale green to yellowish green. Transition from sterile to sporogenous zone gradual. Sporogenous zone 10–30 cm long, 7–10 mm diam., undivided or once-forked. Sporophylls linear-lanceolate, whorled, imbricate, subappressed, abruptly contracting above base into a long, attenuated upper portion that is spreading but apically directed, 5–7 mm long, 1.5–2 mm wide. Sporangia occupying one-sixth of the sporophyll length.

Distribution

Daintree to Tully in NE QLD. Also widespread but scarce throughout the Palaeotropics.

Habit and habitat

A lithophyte or subcanopy epiphyte on riparian trees, usually near watercoarses.

Cultivation

Best cultivated in a hanging container of coarse free draining mix or in a nest-fern in a tropical shaded garden or fernery. This species is less tolerant of cool conditions.

Similar species

Can be distinguished from other Australian Phlegmariurus by bottlebrush like shoots of slender spreading lycophylls and sporophylls.
