Horkelia fusca var. pseudocapitata
Horkelia fusca var. fusca
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 fusca occurs in the Cascade Ranges on both sides of the Columbia River Gorge, primarily around Mount Hood, Oregon, and Mount Adams, Washington. Pending further analysis, all collections of the species from the Cascade Range in Washington are treated here as var. fusca, including some with leaflets and/or petals in the size range of var. parviflora. Plants from lower elevations tend to have greener, more openly branched inflorescences and narrower, more finely divided leaflets; this expression provides the type of Horkelia tenuisecta.
