Perennial, in soil or on or among rocks; rhizome creeping to erect, scaly
Leaves generally all ± alike (or of 2 kinds, fertile and sterile), generally < 50 cm, often < 25 cm; petiole generally thin, wiry, often dark, in transverse section with vascular strands generally 13, less often many in a circle; blade generally pinnate or ± palmate-pinnate (see Adiantum ), often 2 or more compound, lower surface often with glands, ± powdery exudate, hairs, or scales; segments round, oblong, fan-shaped, or otherwise, veins generally free
Sporangia in sori or not, marginal, submarginal, or along veins, sometimes covered by recurved, often modified segment margins (false indusia); true indusia 0; spores spheric, sides sometimes flat, scar with 3 radiating branches
Genera in family: ± 40 genera, 500 species: worldwide, especially dry areas. Definition of Cheilanthes and related genera problematic; traditional limits often untenable.
Plant in soil or rock crevices; rhizome short- to long-creeping-decumbent, generally many-branched, scales generally linear-lanceolate, pale to dark, with darker mid-stripe or not
Leaf < 75 cm; petiole cylindric, reddish brown to blackish; blade generally 23-pinnate, generally oblong to narrowly triangular; segments generally small, ± flat or lower side concave (from recurved margins)
Sporangia along margin, in discrete patches to continuous, partly to completely covered by recurved margin (generally not recurved in C. cooperae)
Species in genus: 150+ species: generally Am, generally dry areas
Etymology: (Greek: lip flower, from location of sporangia)
Horticultural information: DFCLT.
Rhizome short-creeping; scales pale with darker (reddish brown to blackish) mid-stripe extending ± to margin or not
Leaf 614(20) cm, 1.53 cm wide, dark green; petiole < 1 mm wide, scales lanceolate, ciliate at base, pale; blade 3-pinnate; segments small, ± round, lower surface concave, with pale to reddish brown scales, scales < 1 mm wide, ciliate at base, covering more deeply dissected scales, barely exceeding segment margin, upper surfaces glabrous or at least some with deeply dissected scales
Sporangia generally obscured by scales and recurved segment margin
Ecology: Crevices, bases of rocks
Elevation: 3002800 m.
Bioregional distribution: Outer North Coast Ranges, High North Coast Ranges, High Sierra Nevada, San Francisco Bay Area, South Coast Ranges, Modoc Plateau, White and Inyo Mountains
Distribution outside California: Nevada
Hybridizes with C. covillei , C. gracillima.
|YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).|
