The coastal var. titi once occurred in Los Angeles, Monterey, and San Diego counties. It was thought extinct, but one population was discovered on a bluff in Monterey County.
Variety titi is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Most of the habitat of var. tener, restricted to the San Francisco Bay area, the adjacent Central Valley, and the lower valleys of the San Benito and Salinas rivers, has been destroyed by urbanization and agriculture. The plant is now uncommon. Intra-plant and -population leaf variation, first reported by A. Kellogg (1861), has been reviewed by R. C. Barneby (1964).
