Streptanthus oliganthus is an uncommon species of flowering plant in the mustard family known by the common name Masonic Mountain jewelflower.[1] It is native to western Nevada and eastern California , where it grows in the rocky hills east of the central Sierra Nevada. Its habitat includes forest, woodland, sagebrush, and mountain talus. It is a rhizomatous perennial herb producing a hairless, waxy, usually unbranched stem up to about 40 or 50 centimeters in maximum height. The basal leaves have lance-shaped, smooth-edged blades up to 10 centimeters long borne on fuzzy to rough-haired petioles. Leaves higher on the stem have shorter blades which may clasp the stem at their bases. Flowers occur at intervals along the upper stem. Each has a bell-shaped calyx of purple sepals no more than a centimeter long. The petals emerging from the tip are reddish purple or purple-tipped. The fruit is a smooth, flat, straight or slightly curved silique up to 8 to 10 centimeters long.
