This varies a good deal in color and beauty. The stems are smooth and slender, from one to two feet tall, and the leaves are alternate, smooth or downy, delicately cut into many fine divisions. The numerous small flowers are funnel-form, with projecting stamens, and form a close round head, which is an inch or more across, without bracts. The calyx is more or less woolly, with sharp triangular teeth, the tips turned back. Usually the flowers are blue of some shade, deep or pale, sometimes forming patches of color in the fields, but the prettiest I have seen grew in the woods near Santa Barbara, the individual flowers larger than usual and pure white, with bright blue anthers. It is common in Yo-semite, but rather dull bluish-white and not pretty.
