Discussion
Variety ovalifolium is found in eastern California, northwestern Colorado, Idaho, Montana, Nevada, eastern Oregon, Utah, eastern Washington, and Wyoming. It is less widespread than var. purpureum and generally tends to flower earlier than that variety. The two sometimes occur together but do not seem to intergrade, although in some cases the only distinguishing feature is flower color. It is important to note that the yellowish hue of var. ovalifolium will fade in some herbarium material, making identification of older or less well-preserved material difficult. Brownish leaf margins occur on specimens of var. ovalifolium found in northeastern California (Lassen, Plumas, and Siskiyou counties).
