''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. There are only five known populations.〔(The Nature Conservancy )〕 It was once thought to be an intergrade of ''Brodiaea filifolia'' and ''B. orcuttii'', but measurements found this to be false.〔Armstrong, W. (Notes On Santa Rosa Basalt Brodiaea (''Brodiaea santarosae'') )〕 It was described as a new species in 2007.〔Chester, T., W. Armstrong, and K. Madore. (2007). (''Brodiaea santarosae'' (Themidaceae), a new rare species from the Santa Rosa basalt area of the Santa Ana Mountains of Southern California. ) ''Madroño'' 54 187-198.〕 It is on the California Native Plant Society list 3 as a rare and endangered species.〔(Cal Flora )〕 It is a perennial producing an inflorescence bearing bright purple flowers. Each flower has six spreading tepals with a center containing three stamens and narrow or small staminodes, which are flat sterile stamens lying against the tepals.〔Armstrong, W. (Floral Variation in ''Brodiaea santarosae'' )〕 ==References==
