Woodsia oregana

Higher Taxonomy
Family: WoodsiaceaeView DescriptionDichotomous Key

Common Name: CLIFF FERN FAMILY
Habit: Perennial herb in soil or rock crevices; rhizome generally short-creeping, ascending, or erect, scales small to large, generally tan to brown, generally uniformly colored. Leaf: generally tufted or short-spaced, 5--200+ cm, generally +- alike; stipe firm or fleshy (easily crushed), base darker or not, with 2 vascular strands; blade generally 1--3-pinnate, +- glabrous or with hairs, hair-like scales, or gland-tipped hairs on axes, veins generally free (or netted); rachis, costa generally grooved adaxially. Sporangia: sori round, oblong, J-shaped, or linear along veins; indusia 0 or oblong, J-shaped, reniform, or linear, or of many segmented hair- or scale-like fragments or lobes encircling sorus from below; spores elliptic, winged, ridged, or spiny, scar linear.
Genera In Family: +- 15 genera, 700 species: worldwide, especially tropics, wooded areas, but some genera (e.g., Cystopteris, Woodsia) generally temperate. Note: See note, reference (Smith et al. 2006 Taxon 55:705--731) under Dryopteridaceae for removal of genera from that family to this.

Genus: WoodsiaView DescriptionDichotomous Key

Common Name: CLIFF FERN
Habit: Rhizome generally ascending to suberect, short, old stipe bases many. Leaf: often glandular or hairy; stipe base ×-section with 2 vascular strands; blade 1--2-pinnate, segments +- toothed to pinnately lobed, veins free, ending just short of margin. Sporangia: sori round, generally not at margins; indusium cup-like, often of many segmented hair- or scale-like fragments or lobes encircling sorus from below, often of crusty, +- white beads, often obscure in age.
Species In Genus: +- 30 species: generally northern temperate. Etymology: (J. Woods, Britain, b. 1776)

Woodsia oregana D.C. Eaton
NATIVE
Leaf: 5--25 cm, 1--3.5 cm wide, tip +- acute, unforked; hairs on abaxial leaf axes 0 or +- 0.1 mm, cylindric, non-segmented, glandular; pinnae 0.5--2.5 cm, 0.3--1.3 cm wide, pinnately lobed to 1-pinnate, margin fine-toothed. Sporangia: indusium of segmented hairs. Chromosomes: 2n=76,152.
Ecology: Crevices, rock bases; Elevation: 900--2800 m. Bioregional Distribution: KR, CaRH, n&s SNH, SnBr, PR, MP, W&I, DMtns; Distribution Outside California: to British Columbia, eastern Canada, northern United States, Oklahoma, Arizona. Note: Variable. Sterile, nonglandular plants distinguished from Cystopteris fragilis by leaf veins that do not quite reach the margin in Woodsia but do in Cystopteris. If recognized taxonomically, plants differing in chromosome number, spore size [Windham 1993], perhaps other ways, assignable to W. oregana subsp. cathcartiana (B.L. Rob.) Windham (2n = 152), W. oregana subsp. oregana (2n = 76); study needed.
Unabridged Note: Variable. Like Cystopteris fragilis except glandular hairs generally present in Woodsia, absent in Cystopteris; veins ending just before leaf margin in Woodsia at 10×, at leaf margin in Cystopteris.
