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-creeping-decumbent, scales lance-elongate, generally dark, with narrow, lighter margin or not. Leaf: ± alike or fertile, sterile ± dissimilar; axes grooved, light to dark brown; blade 3–4-pinnate, ovate-triangular to 5-sided, glabrous, adaxially ± glossy; pinnae long, narrow, tip pointed, sterile. Sporangia: in small clusters or continuous along margin; false indusia scarious, irregularly toothed.Key to Aspidotis
4 species: generally western North America, also eastern Canada, ± dry, mountain areas. (Greek: shield-bearer, from shield-like false indusia in Aspidotis californica)
Leaf: 3(4)-pinnate, 10–20(40) cm, thin; pinnae pinnately dissected, segments lanceolate to triangular, teeth few. Sporangia: false indusia ± as wide as long, free, 1–2(5) per segment, ± entire or with few coarse or deep, irregular teeth.
