Astragalus brauntonii

Astragalus brauntonii is a rare species of milkvetch known by the common name Braunton's milkvetch. It is a short-lived perennial shrub with lilac flowers that is typically found on carbonate soils in fire-prone areas. It is an opportunistic pioneer species that usually appears in the aftermath of wildfires and other disturbances. It is known from fewer than 20 extant occurrences in the hills and mountains surrounding the Los Angeles Basin in Southern California, as well as an isolated population in northern Baja California. Altered fire cycles, urban development, and habitat fragmentation all pose threats to the survival of the species. It is a federally listed endangered species in the United States....read more on Wikipedia.
