Streptanthus glandulosus is a species of flowering plant in the mustard family known by the common name bristly jewelflower.[2] It is native to California and southwestern Oregon, where it grows in many types of habitat, including grassland, chaparral, and woodlands. Genetic and other analyses indicate that it is a species complex with ten subspecies which evolved as populations were isolated from each other.[3] The complex includes subspecies previously considered separate species, such as the rare Tiburon jewelflower (ssp. niger) endemic to the San Francisco Bay Area.[4] Plants in the complex are variable. In general they are annual herbs growing 10 centimeters to over a meter in height. They may be hairless hairy to bristly. The ephemeral basal leaves have blades borne on winged petioles. Leaves higher on the stem are linear to lance-shaped and clasp the stem at their bases. Flowers occur at intervals along the upper stem. Each flower has an urn-shaped calyx of sepals one-half to over one centimeter long which can be almost any color from white to yellowish to pink or purple to nearly black. Purple, white, or purple-veined white petals emerge from the tip. The fruit is a straight or curving silique up to 11 centimeters long.
