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] California members of Cheilanthes moved to the distantly related Myriopteris; Pellaea breweri to be moved as well, from a to-be-redefined Pellaea; traditional, often untenable limits of genera outside California also being clarified using molecular phylogenetics. —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.
Key to Pteridaceae
Plant in rocky places; rhizome creeping-decumbent, scales brown. Leaf: tufted, deciduous or evergreen, of 2 kinds, fertile more erect, with longer stipes, longer, narrower segments than sterile; stipes dark, scaly at base, tan to ± green, glabrous above base; blades 2–4-pinnate, triangular, lanceolate, or elliptic; veins free. Sporangia: along veins, submarginal, appearing to cover surface at maturity; false indusia linear, from segment base to tip.Key to Cryptogramma
11 species: temperate North America, South America, Europe, Asia. (Greek: hidden line, from protected sori)

2n=60. Generally ± moist talus slopes, crevices, often granitic or volcanic rock; 1800–3650 m. Klamath Ranges, High Cascade Range, High Sierra Nevada, Warner Mountains; to British Columbia, Montana. [Online Interchange]
