Astrolepis cochisensis

Higher Taxonomy
Family: PteridaceaeView DescriptionDichotomous Key

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: AstrolepisView Description 

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. Etymology: (Greek: star scale)

Astrolepis cochisensis (Goodd.) D.M. Benham & Windham
Habit: 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. Chromosomes: n=2n=87.
Ecology: Limestone slopes, crevices; Elevation: 900--1800 m. Bioregional Distribution: DMtns; Distribution Outside California: to Texas, Mexico. Note: Apogamous.
Synonyms: Cheilanthes cochisensis (Goodd.) Mickel; Cheilanthes sinuata (Sw.) Domin var. cochisensis (Goodd.) Munz
