|Distribution||Mascarene Islands, Sri Lanka and southern India, SE Asia, Malesia, NE Queensland to Fiji, Raratonga, Society Islands, Marquesas Islands and the Hawaiian Islands.|
||Epiphytic, or sometimes terrestrial or epipetric, often forming dense mats. Rhizomes creeping, high-climbing, 1.5-3 mm in diameter, dorsiventral; scales brown, to 5 mm long, persistent, later deciduous.
||Fronds monomorphic; stipe 3-7 cm long, spaced 1.5-3 cm apart; blade of adult plants linear-oblong, strongly reduced toward base, pinnules 16–24(–33) mm long, 5–7 mm wide, sessile to shortly stalked, chartaceous, closely spaced, gradually reduced and becoming contiguous or pinnatifid towards apex, acroscopic pinnule margins shallowly incised to the level of the indusium or slightly deeper, lobes rounded, narrowed from base to apex, sometimes apically erose, basiscopic margin concave; veins free, 1–2 times forked; blade of juvenile plants with deeply lobed pinnae.
||Sori submarginal, on 1–several vein endings, separated by marginal incisions; indusium, 0.8–1.5 mm wide, with a weakly concave to weakly convex base.
||Kramer (1970) recognized seven varieties of Lindsaea repens, with only var. marquesensis occurring in the Marquesas Islands. Morphological differences between the varieties of Lindsaea repens are subtle but appear to be consistent and separated geographically. We follow Kramer (1970) in recognizing var. marquesensis, which differs from the other varieties in having margins of the outer pinnules incised to the level of the base of the indusium or slightly deeper, sori borne on 1-several veins, and indusia with weakly concave to weakly convex bases.
