[Wikipedia] Rarity, New Species Designation: Brodiaea santarosae is a rare Brodiaea species known by the common name Santa Rosa brodiaea and Santa Rosa Basalt brodiaea. It is endemic to southern California, mostly in the region around the junction of Orange, Riverside, and San Diego Counties and limited to ancient basaltic soils.[1] There are only five known populations.[2] It was once thought to be an intergrade of Brodiaea filifolia and B. orcuttii, but measurements found this to be false.[3] It was described as a new species in 2007.
