[Wikipedia] Conservation, Endangered Species Status: Threats to this rare species include the invasion of Himalayan blackberry (Rubus armeniacus) into its habitat. One of the two occurrences is next to a road where there is heavy CalTrans activity.[2] The plant has no federal protection but it is a state-listed endangered species in California, which means that killing or possessing this species is prohibited unless permitted by the California Department of Fish and Game (California Fish and Game Code Section 2080).
