Pellaea mucronata var. mucronata

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: PellaeaView DescriptionDichotomous Key

Common Name: CLIFF-BRAKE
Habit: Plant in soil or rock crevices; rhizome short- to long-creeping, scales overlapped, narrowly linear, light- to red- or medium-brown, often with dark mid-stripe. Leaf: erect, persistent, < 1 m; stipes +- cylindric, generally dark or red-brown to +- black, +- shiny, glabrous; blade 1--4-pinnate; segments generally stalked, generally free, linear to rounded, lobed or not, often folded lengthwise when dried; veins generally free. Sporangia: in +- continuous, submarginal bands, among a +- white to +- yellow exudate or not; segment margin generally recurved, generally modified; spores tan to light yellow.
Species In Genus: +- 35 species: tropics, temperate, few in Europe, 0 in Asia. Etymology: (Greek: dusky, from blue-gray leaves) Note: Occasionally cultivated; as defined by Tryon (1957), polyphyletic (Kirkpatrick, 2007).
Unabridged Note: Occasionally cultivated. Molecular data suggest Pellaea in the sense of Tryon (1957) is polyphyletic with monophyletic Astrolepis and Pellaea sect. Platyloma, as well as elements of Paragymnopteris and Paraceterach nested within (Kirkpatrick, 2007).
Species: Pellaea mucronataView Description 

Common Name: BIRD'S-FOOT FERN
Habit: Rhizome short-creeping, branched, > 8 cm, 0.5--1 cm wide; scales +- brown, mid-stripe dark. Leaf: +- clustered, +- green to +- purple; stipe < 2(3) mm wide; blade 2--3(4)-pinnate, narrowly triangular to oblong; segments 2--6(8) mm, 0.5--2(4) mm wide, linear to oblong, with mucro. Sporangia: 64-spored. Chromosomes: 2n=58.


Pellaea mucronata (D.C. Eaton) D.C. Eaton var. mucronata
NATIVE
Leaf: 20--40(60) cm, 5--15 cm wide; blade 2--3(4)-pinnate; pinnae not overlapped, generally +- spreading to widely ascending; fertile segments not appearing folded in half, recurved margins not meeting abaxially.
Ecology: Rocky or dry areas; Elevation: 20--2400 m. Bioregional Distribution: KR, NCoR, CaR, SN, GV (Sutter Buttes), CW, SW, SNE, DMoj (desert mtns and lower montane slopes, canyons); Distribution Outside California: Baja California. Note: Hybrids with Pellaea brachyptera (pinnae linear, well-spaced on elongate 2 ×-pinnate axes), Pellaea truncata (some pinnae irregularly lobed, costae +- 90° from rachis) +- common.
