A densely tufted perennial, more or less erect in growth, and often covered with minute hairs. It is sparingly branched and grows from four to ten inches high. The starry white flowers are much larger than those of the two preceding species, and have ten yellowish stamens. They are loosely clustered, and the five petals are nicked at the apex into two rounding lobes. The calyx is less than half the length of the petals. The leaves are small and grass-like and occur sparingly in alternating pairs upon the stalk. This Chickweed is found in dry, rocky places from Labrador to Alaska, and south to Georgia, Missouri, Nevada and California. It blossoms from April to July.
