Chert grassland n exp
Seen ready to open its buds on a moderate clearing in the oak woodland canopy. This colony is fully naturalized here. Numerous of these plants were seen in an area of about 60 square meters.
Keyed using Howell's Marin Flora (don't have the Sonoma one, Jepson's annoying for this group). Bractlets seem "obovate," petals glabrous, common, weedy along trail/road-side.
