Perennial, on plants, rocks, in rock crevices, less often in soil, humus, or on dunes; rhizome short- to long-creeping, branched, glaucous to not, scaly
Leaves ± alike or of 2 kinds, fertile and sterile; petiole thin to thick, straw-colored or green to brown or black, generally jointed to persistent knob on rhizome; blade generally simple to 1-pinnate, membranous to fleshy or leathery; veins free to fused, generally forked
Sporangia: sori round to elongate, rarely linear, generally 1 per areole, in 1several rows on each side of segment midrib; indusium 0; spores generally ± elliptic, ± smooth to coarse-tubercled or -ridged, scar linear
Genera in family: ± 46 genera, ± 650 species: worldwide, especially Old World tropical. Numbers of genera, species depend on treatment; many species cultivated.
Rhizome long-creeping; scales lanceolate, ± brownish, 1-colored or often with darker central area or midstripe
Leaves 0.210(20) dm, ± alike or fertile > sterile; petiole glabrous to scaly; blade 1-pinnate to generally deeply pinnately lobed, rarely simple and unlobed, glabrous to hairy, glandular or not, scales on lower surface midrib near base generally lanceolate or linear-lanceolate, generally ± brown; veins free to fused
Sporangia: sori in 1 row on each side of segment midrib, generally raised, sometimes including branched or unbranched, glandular hairs, sporangium-like structures, or shriveled sporangia; spores yellow
Species in genus: ± 160 species: generally New World, tropical, some temp, few boreal
Etymology: (Latin: many feet, from rhizome)
Reference: [Whitmore & Smith 1991 Madroño 38:233248]
50% or more malformed spores indicates hybrid involving 2 or more species in CA.
Rhizome (3)510 mm diam, ± glaucous or not, taste bland or acrid; scales ± 1-colored
Leaf summer-deciduous; blade (5)1025(35) cm, deltate to ovate, membranous to fleshy, often firm, upper surfaces of midribs hairy to ± glabrous, segments serrate, tips obtuse to acute, veins generally 1050% fused
Sporangia: sori 1.53.5 mm, round to generally ovate, generally ± sunken, flat, sometimes with short, branched, glandular hairs
Ecology: Shaded canyons, streambanks, n-facing slopes, roadcuts, cliffs, coastal bluffs, rocks, often granitic or volcanic, humus, not on plants
Elevation: < 1520 m.
Bioregional distribution: North Coast, Central Coast, Outer South Coast Ranges, Southwestern California (except San Jacinto Mountains)
Distribution outside California: Baja California
Hybrids with P. hesperium (SnBr) uncommon, sterile, 2n=111; see P. calirhiza , P. scouleri.

|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).|
