[Wikipedia] Description, Range: Streptanthus barbiger is a species of flowering plant in the mustard family known by the common name bearded jewelflower.[1] It is endemic to California, where it is limited to the North Coast Ranges. It grows in woodlands and chaparral habitat, often on serpentine soils. It is an annual herb producing a branching stem up to about 80 centimeters in maximum height. Leaves near the base of the stem are lance-shaped to oval and pointed, usually with toothed edges, the blades measuring up to 7 centimeters long. Leaves higher on the stem may be longer but are narrower and have smooth edges. Flowers occur at intervals along the upper stem. Each has a spherical to urn-shaped calyx of greenish yellow or purple sepals under a centimeter long. Whitish or purple-tinged petals up to a centimeter long emerge from the tip. The fruit is a long, flat, curving silique which may be 7 centimeters in length. (link added by Mary Ann Machi)
