The photo above shows a close-up of the inflorescence of few-flowered clover as seen from Catherine Creek..........May 1, 2005. Note the involucre subtending the flower head as well as the red-tipped calyx lobes.
White-tip clover is a glabrous annual wildflower with one to several prostrate to ascending stems from 10-60 cm long. The stems are thin and weak and often diffusly branched. The leaves are alternately arranged along the stems and are ternately compound. The stipules are ovate in shape and deeply incised along the margin. The leaflets measure 5-20 mm long and are oblanceolate to obcordate in shape with minute, sharp teeth along the margins.
The flower heads are 1-2 cm wide and contain 3-40 flowers. They are immediately subtended by a saucer-shaped, glabrous involucre which is irregularly lobed and deply cut about half its length. The calyx tube is narrowly bell-shaped with the teeth considerably longer than the tube. The corolla is about 5-20 mm long and purple in color, often with a lighter to whitish tip. The flowers typically age to a purplish-brown color.
White-tip clover is found on moist, open ground along streams and in vernally moist meadows.
White-tip clover may generally be found west of the Cascade and Sierra Nevada Mts. from British Columbia south through Washington and Oregon to California but is occasionally found eastward to Idaho, Utah and Montana.
It may be found between the elevations of 100'-3000' from west of Stevenson, WA eastward to near the Deschutes River.
