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. eFlora Treatment Author: Ruth E.B. Kirkpatrick, Alan R. Smith & Thomas Lemieux, except as noted Scientific Editor: Alan R. Smith, Thomas J. Rosatti.
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. Etymology: (Greek: unwettable) Note: Widely cultivated. eFlora Treatment Author: Layne Huiet, Ruth E.B. Kirkpatrick, Alan R. Smith & Thomas Lemieux Reference: [Huiet et al. 2015 PhytoKeys 53:73--81]
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, without yellowish exudate among sporangia. Chromosomes: 2n=60. Ecology: Uncommon (or locally common). Shaded, rocky or moist banks, exposed sites or not; Elevation: < 2300 m. Bioregional Distribution: NCoR, CaRF, n SNF, s SNH, SnJV, CCo, SCoRO, SW, GB, D; Distribution Outside California: generally southern United States; worldwide, especially temperate.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
