Brodiaea filifolia (thread-leaved brodiaea) is a perennial herb in the Themidaceae family with underground bulb-like storage stems. Individual plants are less than 16 inches (40 centimeters) tall, with narrow leaves and saucer-shaped violet flowers arranged in a loose umbel. Sixty-eight
discontinuous occurrences of this plant are distributed across southern California from the foothills of the San Gabriel Mountains to Arrowhead Hot Springs in the
western foothills of the San Bernardino Mountains, south through eastern Orange and western Riverside Counties to central San Diego County, California.
