SOUTHERN MAIDENHAIR

Higher Taxonomy
Family: PteridaceaeView DescriptionDichotomous Key

Common Name: BRAKE FAMILY
Habit: 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.
Genera In Family: +- 40 genera, 500 species: worldwide, especially dry areas. Note: CA 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 CA also being clarified using molecular phylogenetics.

Genus: AdiantumView DescriptionDichotomous Key

Habit: Plant in soil or rock crevices; rhizome short-creeping, scales variously colored. 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.
Species In Genus: +- 200 species: tropics, temperate. Etymology: (Greek: unwettable) Note: Widely cultivated.

Adiantum capillus-veneris L.
NATIVE
Leaf: generally (7)20--40(50+) cm; stipe dark brown to +- black; blade 2--3-pinnate; pinnules cut or lobed often > 1/4 way to base, often with < 4 +- irregular lobes, margins at base converging at 45--90°, stipe color often extending gradually into base, midvein often part way along 1 margin. Sporangia: sori (and false indusia) (2)3--11 per pinnule, generally < 5 mm. Chromosomes: 2n=60.
Ecology: Uncommon (or locally common). Shaded, rocky or moist banks, exposed sites or not; Elevation: < 2000 m. Bioregional Distribution: KR, NCoR, CaRF, n SNF, s SNH, SnJV, CCo, SCoRO, SW, GB, D; Distribution Outside California: generally southern United States; worldwide, especially temperate. Note: Widely cultivated.
