Woodsia oregana D.C. Eaton ssp. cathcartiana (B.L. Rob.) Windham. Rocky Mountain Woodsia. CalPhotos. Jepson eFlora. SEINet Taxon. Golden Flora.
Of the three characters that distinguish subsp. cathcartiana from subsp. oregana, two, spore size and adaxial epidermal cell size, require measuring in units of µm, something outside the usual abilities of the field botanist. The third character, regarding the cells on pinnule margins being irregular in shape making the margins appear ragged, can be seen with a good microscope.

Weber & Wittmann (2012) distinguish between L. perenne and L. lewisii with the character of heterostyly in which some plants have styles longer than stamens and others with styles shorter than stamens. They apply homostyly to L. lewisii noting that the styles and stamens are approximately equal. My plants (Coll. No. 1383) consistently have styles longer than stamens. The key in Ackerfield (2015), based on plant structure and overall shape is not helpful because of the range of characters observed with this collection.

(Described from Coll. No. 926, 25 May 2013.

APG3 treats Leucocrinum in the Anthericum group of the Agavoidae subfamily of the Asparagaceae, which it then describes as a “ … highly unsatisfactory family.” The Plant List also uses Asparagaceae. FNANM, USDA Plants, and W&W(2012) retain Leucocrinum in Liliaceae. TJM2 (2102) refers it to Agavaceae. Snow (2009) places Leucocrinum in Anthericaceae, along with Echeandria.
