Discussion

Of conservation concern.

Eriogonum crocatum is known only from the Conejo Grade area of the Santa Monica Mountains in Ventura County. A population in the Malibu Hills of Los Angeles County sampled by M. E. Jones (26 Apr 1926, DS, POM) has not been rediscovered. The species is rare, and the state of California considers it worthy of protection. Federal action has been long delayed. The species is widely cultivated and is one of the more popular wild buckwheats in the garden. Great care should be taken to prevent its escape from cultivation.
