Chorizanthe valida (Sonoma spineflower)
by Doreen Smith
This is one of the rarest plants in the world now found as a natural population only on Point Reyes National Seashore. There is some doubt that the original type specimen really came from Sonoma County and it is possibly a Marin endemic. Sonoma botanists need to check for it near Duncan’s Mills to refute this statement!
