Yellow owl-clover is an attractive annual wildflower with slender, erect, simple
or sparsely-branched stems from 10-35 cm high. The leaves are all on the stems
and are narrowly linear-lanceolate in shape with entire margins. They are 1.5-3.5
The inflorescence is narrow and loose below, and about 10 cm long. The bracts
are shorter an wider than the leaves and 3-parted, the lobes arising near the
base of the bract. The lower bracts are 2.5-3 cm long, the upper are much shorter.
The calyx is 6-8 mm long and equally cleft about one third of its length. The
deep yellow corolla is 9-12 mm long, the tube gradually widening to the funnel-like
throat. The upper lip is 2-4 mm long and is short in broad in outline. The lower
lip is slightly expanded and about the same length as the upper lip.
Yellow owl-clover may be found in open grassy to sagebrush meadows and open
stands of aspen.
Yellow owl-clover may be found from British Columbia south to the east of the
Cascade Mts. to Mono and Fresno Counties in California and east Michigan, Minnesota,
Nebraska, Colorado and northern New Mexico.
