Perennial herb, 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).Key to Cheilanthes
150+ species: generally America, generally dry areas. (Greek: lip flower, from location of sporangia)
Rhizome short-creeping; scales light to red-brown, generally with dark mid-stripe. Leaf: 6–15(18) cm, 1.5–3 cm wide, pale green, scales 0; stipe ± 1 mm wide, hairs < 2 mm, pale or tan with ± orange constrictions; blade generally 3-pinnate; segments small, ± round, abaxially concave, hairs generally not intertwined, long, ± white to ± brown, sparse adaxially, dense abaxially. Sporangia: 32-spored, partly obscured by hairs, less so by segment margin.
n=2n=90. Generally limestone crevices, slopes, cliffs; 1200–3000 m. Transverse Ranges, White and Inyo Mountains, Desert Mountains; to British Columbia, Montana, central United States, Mexico. Apogamous. [Online Interchange]
