Few-flowered eriastrum as seen at Fort Rock State Park, Lake County, Oregon.....May 18, 2016.
Few-flowered eriastrum is a small upright annual to 30 cm tall. It may be freely-branched when fully developed.
The leaves are primarily on the stem, with the leaves being as long as 1 to 3 cm, either linear and entire as in variety sparsiflorum, or with 1 to 3 pairs of lateral segments near or below the middle of the leaf in variety wilcoxii.
The infloresence consists of small, few-flowered heads. The calyx of each flower is unequally lobed, and the petals blue to white, about 7 to 13 mm long, the lobes 2 to 5 mm long.
Few-flowered eriastrum inhabits dry, open, often sandy places in the plains and foothills.
Eriastrum sparsiflorum is found east of the Cascade Mts. from central Washington south through eastern Oregon to southern California, and eastward to central Idaho and western Utah.
