Horkelia fusca var. pseudocapitata
Horkelia fusca var. filicoides
The application of the epithet pseudocapitata here differs significantly from that of P. A. Rydberg (1908c), D. D. Keck (1938), and most floras, who used it for the taxon that is here called var. brownii. Instead, var. pseudocapitata encompasses the bulk of what had been called var. (or subsp.) capitata, except in mountains bordering the Palouse Prairie in Idaho, Oregon, and Washington. For nomenclatural details, see B. Ertter and J. L Reveal (2007).
As here circumscribed, var. pseudocapitata is a relatively large, big-petaled variety that grows in the mountains in and bordering the northern Intermountain Region in northeastern California (primarily the Warner Mountains), northern Nevada, southeastern Oregon, and southern Idaho, extending northward along valleys from Camas to Blaine counties. Intermediate plants are common where the range intersects those of var. brownii, var. capitata, and var. parviflora, though in the core of its range var. pseudocapitata is reasonably distinctive and uniform.

Variety filicoides is known from the southern Cascade Range of southwestern Oregon, primarily in open lodgepole pine forests north and west of Crater Lake. This is the only variety in which the flowers are usually arranged individually rather than clustered into glomerules, at least in fully expanded inflorescences; some populations out of the core range have more congested inflorescences and are transitional to var. parviflora in this regard.
