CALIFORNIA LACE FERN

Higher Taxonomy
Family: PteridaceaeView DescriptionDichotomous Key

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.

Genus: AspidotisView DescriptionDichotomous Key

Habit: Plant in soil or rock crevices; rhizome short-creeping-decumbent, scales lance-elongate, generally dark, with narrow, lighter margin or not. Leaf: +- alike or fertile, sterile +- dissimilar; axes grooved, light to dark brown; blade 3--4-pinnate, ovate-triangular to 5-sided, glabrous, adaxially +- glossy; pinnae long, narrow, tip pointed, sterile. Sporangia: in small clusters or continuous along margin; false indusia scarious, irregularly toothed.
Species In Genus: 4 species: generally western North America, also eastern Canada, +- dry, mountain areas. Etymology: (Greek: shield-bearer, from shield-like false indusia in Aspidotis californica)

Aspidotis californica (Hook.) Nutt. ex Copel.
NATIVE
Leaf: 3(4)-pinnate, 10--20(40) cm, thin; pinnae pinnately dissected, segments lanceolate to triangular, teeth few. Sporangia: false indusia +- as wide as long, free, 1--2(5) per segment, +- entire or with few coarse or deep, irregular teeth. Chromosomes: 2n=60,120.
Ecology: Rock outcrops, crevices; Elevation: 20--1300 m. Bioregional Distribution: NCoR, CaRF, SN, GV (Sutter Buttes), CW, SW; Distribution Outside California: Baja California.
