Higher Taxonomy
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.

Astrolepis
Habit: Plant in soil or rock crevices; rhizome +- short-creeping-decumbent, scales generally linear to lance-linear, toothed, pale to red-brown, older with a dark, irregular central area or not. Leaf: axes generally orange to red-brown, scaly; blade 1-pinnate, linear, pinnae shallowly pinnately lobed or dissected or not, adaxially with stellate scales. Sporangia: along veins, obscured by dense scales; segment margin unmodified, not recurved. Species In Genus: +- 6 species: southwestern United States through South America.
