Many not yet in flower, so later would be better for surveys. I mapped some on Calflora but didn't explore far. I kept finding them as I went south in the wash, so more thorough surveys would likely find many more in possibly both directions in the wash from where currently mapped.
Growing in sand lens with Eriastrum densifolium ssp. sanctorum. Small patch of perhaps 20 individuals.
