Discussion

Dalea ornata is nearly endemic to the Columbia-Snake river basin. In California, the species is known only from the Shaffer Mountain region in Lassen County.

Some herbarium labels comment on the lemon odor of Dalea lumholtzii. Although the epistemonous petals are generally blue or bluish, white-petaled plants are not uncommon in the flora area.
