|discussion=<p>Variety brownii here takes the place of var./subsp. pseudocapitata as used in D. D. Keck (1938) and most floras; this variant was included within <i></i>var.<i> parviflora</i> by B. Ertter (1993d). The diagnostic feature is the ash gray leaflets, which also tend to be more narrowly cuneate than in other varieties. The variety occurs from Mount Shasta in Siskiyou County east to southwestern Modoc County and southeast to Sierra Valley in Plumas and Sierra counties, California, skirting the range of <i></i>var.<i> tenella</i>. Morphologically comparable plants occur as far south as the California-<i>Nevada</i> border on the south side of Lake Tahoe, and at least one collection from <i>Nevada</i> (Reno, Hillman s.n., POM) is closest to this variety. Populations from the southeastern end of the range tend to be larger and less ash gray than those in the vicinity of Mount Shasta. Most references to <i></i>var.<i> brownii</i> (as var./subsp. pseudocapitata misapplied) from Oregon are probably best attributed to the polymorphic <i></i>var.<i> parviflora</i>, but at least one collection from Klamath Lake (Newberry s.n., GH) fits well in <i></i>var.<i> brownii</i>.</p>
