Pellaea breweri D.C. Eaton
Habit: Rhizome short-creeping, branched, > 10 cm, 5(7) mm wide; scales +- thread-like, red-brown, dark mid-stripe 0. Leaf: clustered, 8--20(25) cm, 2--3(4) cm wide, pale greenish; stipe < 2 mm wide, fracture lines at base many; blade 1-pinnate, oblong, rachis green at tip; pinnae < 2 cm, < 1.5 cm wide, lance-ovate, deeply 2(3)-lobed. Sporangia: 64-spored; spores dark to light brown. Chromosomes: 2n=58.
Ecology: Generally n-facing granite rock crevices, slopes; Elevation: 1500--3700 m. Bioregional Distribution: KR, CaRH, SNH, SnBr, GB, DMtns; Distribution Outside California: to Washington, Idaho, Colorado.
Unabridged Note: Molecular evidence suggests that Paragymnopteris marantae (L.) K.H. Shing of Eurasia and Paragymnopteris sargentii (H. Christ) K.H. Shing of China are sister to each other, that both are sister to Pellaea breweri, and that these 3 form the earliest diverging pellaeoid clade (Kirkpatrick 2007).
