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- to long-creeping[-decumbent], generally many-branched, scales generally lance-linear, pale to dark, mid-stripe dark or not. Leaf: < 75 cm, young leaf tip hooked or coiled; stipe cylindric, red-brown to +- black; blade generally 2--3-pinnate, generally oblong to narrowly triangular; segments generally small, +- flat or abaxially concave (from recurved margins). Sporangia: along margin, in discrete patches to continuous, partly to completely covered by recurved margin (generally not recurved in Myriopteris cooperae). Etymology: (Greek: myriad fern, from much divided leaf blades) Note: Includes all CA members of Cheilanthes as treated in TJM2 (2012). eFlora Treatment Author: Ruth E.B. Kirkpatrick, Alan R.

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.
