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-creeping- decumbent, generally 3–5(8) mm wide, scales lance- linear, mid-stripe dark.Key to Pentagramma
Leaf: stipe 5–20(32) cm, 0.5–2(3) mm wide; blade generally 2–3- pinnate, 2–8(15) cm, triangular or generally 5-sided, with white or yellow exudate abaxially, with exudate or not adaxially, main axis shallowly to deeply grooved adaxially; lowermost pinnae more strongly developed on basal side; veins free.
Sporangia: along veins ± throughout; segment margins unmodified, recurved or not.
2 species: w North America. (Greek: 5 lines, for leaf blades) A puzzling complex of intergrading chemical, chromosomal, and morphological variants (see Yatskievych et al. 1990 Amer Fern J 80:9–17).
Rhizome tip, including scales, covered with white exudate.
Leaf: stipe dark brown to generally ± black, with white exudate; blade 2–8(12) cm, pale to olive green, both surfaces with white exudate; lower pinnae 2–6(8) cm.
2n=60. Generally in or near granitic soil, rock, boulders; 100–1200 m. Sierra Nevada, Inner South Coast Ranges.
