Plants pendulous, usually with flaccidly hanging divisions, the terminal divisions often aggregated in fasciculate clusters, to 60 cm long. Shoots homophyllous or gradually heterophyllous, equally thick throughout, 20–30(–45) mm in diam. incl. leaves, or gradually tapering to 10–15 mm in diam. in terminal, densely sporangiate divisions. Stems excl. leaves 0.8–1 mm thick at the base, slightly tapering upward, almost straight to somewhat sinuous, but not sharply flexuous, pale transparently stramineous, the vascular tissue usually visible through the cortex. Leaves of basal divisions spirally arranged, single, or in occasional pairs or whorls of 3, not predominantly whorled, forming ca 6 indistinct longitudinal ranks, subdistant, 0.5–3 mm apart, soft-herbaceous, perpendicular to spreading-ascending, straight to slightly falcate, usually with the lamina vertical due to a twist of the lamina base, linear-lanceolate, widest in the basal third or quarter, distinctly narrowed into a petiole-like, twisted, usually perpendicular or deflexed lamina base, 13–25 × 1–2 mm, flat, or with slightly revolute, smooth margins. Leaves of middle and terminal divisions spirally arranged, paired or borne in irregular, alternating whorls of 3, spreading to perpendicular, conform, or usually narrower, (5–)7–15(–20) × 0.7–1.5 mm, transparently to brownish green, or rarely reddish tinged. Sporangia ca. 1.5 mm in diam.

Distribution:—Throughout the Amazonian lowland region of Colombia, Venezuela (AM-BO-DA), Ecuador, Peru, Bolivia, Brazil, the three Guianas and Northern coastal Brazil to Bahia.

Habitat:—Epiphytic in lowland rain forest and riverine forest. 100–1800 m elev.
