Ethnobotany: There is no use recorded for this species, but other species in this genus have uses. Etymology: The meaning of Tephrosia is unknown, while means thurberi is named after Dr. George Thurber (1821-1890), called the most accomplished horticulturist in America, and botanist and quartermaster of the Mexican Boundary Survey, 1850-1854.
