Descripción

Rhizomes long- to short-creeping, scaly; fronds small to medium-sized, monomorphic; stipes glabrous, stramineous to castaneous, often quadrangular; blades (simple–)1–2(–3)-pinnate, anadromous; segments generally dimidiate, membranous to chartaceous; veins free (in ours), rarely netted without included veinlets; sori submarginal in a continuous or interrupted line, subtended by marginfacing indusia, paraphyses generally present; spores tetrahedral (in ours), rarely bilateral; x=34, 41, 47, 50.A

Discusión taxonómica

Lindsaea is a genus of 150 species, about 1⁄3 from the American tropics, mostly though of Southeast Asia and adjacent Pacific area. It is most closely allied to Odontosoria (Wolf, 1995). Lindsaea is probably an ancient genus, judging from its diverse chromosome numbers (x=34, 41, 47, 50), protostelic, scale-hair transitions, and broad distribution.
At low to middle elevations, in wet forests, it often grows with Adiantum, with which it is superficially confused, and mixed collections or misidentifications frequently result. Lindsaea resembles Adiantum in blade dissection, segment shape and marginal sori, but is distinct in the paler axes and the sori with outward-opening (extrorse) indusia.
