Discussion

Of conservation concern.

Variety indicta was known only from the type in Tehama County until rediscovered in 1990 in western Shasta County, confirming that this is a distinct variety in the forested hills rimming the northern Sacramento Valley (B. Ertter and J. L. Reveal 2007). One other historic collection of Horkelia daucifolia from Shasta County (Montgomery Creek, Smith s.n., CAS) is more similar to var. daucifolia.
