Hairy owl-clover is a small annual wildflower with simple to branched stems, the branches held erect. It ranges from 10-40 cm high. The herbage is fairly densely covered with long, soft and shaggy hairs. The stem leaves are narrowly linear-lanceolate with entire margins on the lower leaves, the upper leaves with 1-2 pairs of narrow lobes. The leaves are 2.5-6 cm long.
The inflorescence is long and loose below. The bracts are wide at the base and deeply cleft with 1-3 pairs of long, narrowly linear lobes. The calyx is 8-13 mm long and about equally cleft in front and on the back. The corolla is 1.2-2 cm long,, narrow at the base and gradually expanding to the fairly narrow throat. The upper lip consists of a slender straight and pointed galea from 3-4 mm long. The lower lip consists of 3 sacs which are shorter than the galea. The corolla varies from white to creamy or yellow.
Hairy owl-clover is found in moist meadows and in the beds of vernal pools from the lowlands to moderate elevations in the mountains.
Hairy owl-clover is found from southern British Columbia south on both sides of the Cascades to southern California and east to Idaho and Nevada.
