Discussion
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).
