Ruth E.B. Kirkpatrick, Alan R. Smith & Thomas Lemieux, except as noted

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.
± 40 genera, 500 species: worldwide, especially dry areas. [Windham 1993 FNANM 2:122–186] California 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 California also being clarified using molecular phylogenetics. —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.

Key to Pteridaceae

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.
± 6 species: southwestern United States through South America. (Greek: star scale)

A. cochisensis (Goodd.) D.M. Benham & Windham SCALY CLOAK-FERN
Rhizome short; scales ± 10 mm, 0.1–0.5 mm wide, linear; teeth ± sparse, more pronounced in distal 1/2 or not. Leaf: stipe 3–6(10) cm, 1–1.5 mm wide, scales appressed, 0.5 mm, ± white; blade 1-pinnate, 8–15(20) cm, tapered to tip; pinnae < 0.5 cm, stalk jointed, lobes 0–3 pairs, generally obtuse at tip, adaxially with persistent, stellate scales, abaxially with lanceolate, ± white to tan, densely toothed and finely dissected scales covering small (< 0.1 mm) glandular hairs. Sporangia: 32-spored, in submarginal band when mature, ± visible, erupting through scales.
n=2n=87. Limestone slopes, crevices; 900–1800 m. Desert Mountains; to Texas, Mexico. Apogamous. [Online Interchange] {CNPS listed}
