Pellaea mucronata
BIRD'S-FOOT 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: 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).

Pellaea mucronata (D.C. Eaton) D.C. Eaton
NATIVE
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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
