Descripción
Rhizomes long-creeping, horizontal, 1–1.5 mm diam.; rhizome scales lanceolate, concolorous tan to brown, thin to sclerotic, 1–2 mm long, entire; fronds to 25 cm long, 3–20 cm apart on the rhizomes; stipes 1⁄3–1⁄2 the frond length, blackish brown, lustrous, terete, with sparse, linear-lanceolate, tan, thin, subentire scales with occasional hair-teeth and hairs at base and some reduced nearly hair-like scales; blades narrowly lanceolate, not especially narrowed proximally, 3–4-pinnate with bead-like segments; pinnae 10–14 pairs, equilateral; adaxial surfaces glabrous but with loose, wool-like mat of white hairs 1–1.5 mm long extending beyond segment margins abaxially; abaxial surfaces with a dense covering of scales, those on the midribs linear-lanceolate, castaneous at bases, on the segments lanceolate, with long marginal cilia throughout the scale length, some scales reduced nearly to stellate hairs; laminar margins recurved but not strongly differentiated, obscured by scales and hairs; spores dark brown; n=2n=90, apogamous (USA).A

Discusión taxonómica
Cheilanthes lindheimeri is distinct by its long-creeping rhizome with broad, concolorous scales and the adaxial blade surfaces appearing to be densely covered with fine curly hairs, though these are actually hairs from margins of abaxial costal scales that extend beyond the segment margins.A
