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 rock crevices; rhizome short- to long-creeping[- decumbent], generally many-branched, scales generally lance- linear, pale to dark, mid-stripe dark or not.
Leaf: < 75 cm, young leaf tip hooked or coiled; stipe cylindric, red-brown to ± black; blade generally 2–3- pinnate, generally oblong to narrowly triangular; segments generally small, ± flat or abaxially concave (from recurved margins).
Sporangia: along margin, in discrete patches to continuous, partly to completely covered by recurved margin (generally not recurved in Cheilanthes cooperae).
150+ species: generally Am, generally dry areas. (Greek: lip flower, from location of sporangia)
