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.
Plant in soil or rock crevices; rhizome short-creeping, scales variously colored.Key to Adiantum
Leaf: < ± 1 m; stipe cylindric, generally dark red-brown to ± black, shiny, ± scaly at base; blade 2–3- pinnate or ± palmate-pinnate (1st division ± palmate, subsequent ones pinnate), pinnae stalked, fan-shaped or oblong, generally lobed, toothed, or both; axes, blades lacking colored exudate.
Sporangia: borne along veins on and covered by highly modified, recurved part of segment margin, appearing to run together at maturity; false indusia ± semicircular to linear; spores generally smooth, tan.
± 200 species: tropics, temperate. (Greek: unwettable) Widely cultivated.
Leaf: 20–75(100+) cm; stipe red-brown to ± black; blade ± palmate-pinnate; pinnules cut or lobed generally < 1/2 way to midrib, often with > 4 regular lobes, margins at base converging at 45–90°, stipe color extending gradually into base, midvein generally part way along 1 margin.
Sporangia: sori (and false indusia) generally 4–6 per pinnule, generally < 3 mm.

| Bioregions in which taxon occurs | Red area (if present) is the part of the bioregion lying between the upper and lower elevation limits of the taxon; markers link to CCH specimen records. If the markers are obscured, reload the page [or change window size and reload]. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. |
