Discussion | Of conservation concern. Subspecies pumila is found only on the summits of Upper Table Rock and Lower Table Rock, in Jackson County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Subspecies californica occurs in Butte County on the eastern edge of the Sacramento Valley and on Table Mountain. It is sympatric with Limnanthes alba subsp. alba; it flowers earlier. J. A. Dole and M. Sun (1992) found no evidence of hybridization between them.
