Cheilanthes lendigera (Cav.) Sw.
Descripción
Rhizomes long-creeping, horizontal, ca. 3 mm diam.; rhizome scales linear-lanceolate, mainly concolorous tan to orange, becoming only weakly bicolorous or dark brown concolorous with age; fronds to 37 cm long, spaced; stipes generally 1⁄2–3⁄5 the frond length, dark castaneous, terete, lustrous, with long soft orange hairs 1.5–3.5 mm long; blades deltate, tripinnate-pinnatifid to quadripinnate, the segments round, bead-like, generally ca. 1 mm across, discrete; pinnae 10–20 pairs, equilateral, narrowly deltate; adaxial surfaces glabrous; axes and abaxial surfaces with long orange hairs; sori at vein ends, laminar margins curved and strongly modified into 0.2–0.3 mm wide entire false indusia, nearly covering abaxial surfaces of segments, with sparse hairs at the indusial-laminar interface; spores dark brown; 2n=120 (USA).A

Discusión taxonómica
Cheilanthes lendigera is distinct from other members of this complex by its relatively broad false indusia with scattered hairs on the indusial-lamina, margin interface, and frond indument of hairs only 1–2 cells wide. Cheilanthes mexicana differs in having the indusia virtually absent, and Cheilanthes marsupianthes has linear stipe scales 4–5 cells wide and lacks hairs on the indusial-laminar margin interface.
Reeves (1979) suggested that C. lendigera is a fertile allotetraploid of C. marsupianthes X mexicana.
