Perennial, in soil or on or among rocks; rhizome creeping to erect, scaly.
Leaf: generally all ± alike (or of 2 kinds, fertile, sterile), generally < 50 cm, often < 25 cm; stipe generally thin, wiry, often dark, ×-section with vascular strands generally 1–3, less often many in circle; blade generally pinnate or ± palmate-pinnate (see Adiantum), often >= 2- compound, abaxially often with glands, ± powdery exudate, hairs, or scales; segments round, oblong, fan-shaped, or other, veins generally free.
Sporangia: in sori or not, marginal, submarginal, or along veins, covered by recurved, often modified segment margins (false indusia) or not; true indusia 0; spores spheric, sides flat or not, scar with 3 radiating branches.
± 40 genera, 500 species: worldwide, especially dry areas. [Windham 1993 FNANM 2:122–186] Definition of Cheilanthes, related genera problematic; traditional limits often untenable. —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.

Key to Pteridaceae

Plant in soil or granite rock crevices; rhizome short-creeping to ± erect, scales lance- linear.
Leaf: stipe generally cylindric, dark brown to black, glabrous to ± scaly; blade 2–4- pinnate, segments generally sessile, ± narrower at base or not.
Sporangia: in ± continuous, marginal bands; segment margin recurved, partly covering sporangia, unmodified; spores finely ridged or granular, often ± black.
34 species: generally Mex, sw US, few in Caribbean, South America. (Greek: false cloak, from leaf blade margin not reflexed as it is in Cheilanthes)
