Stem stout, hairy, 2 to 3 feet tall, branching above at the involucre which is composed of two to five, usually three, short-petioled leaves; the lateral peduncles often bearing secondary involucres of smaller leaves. Basal leaves long petioled, broader than long, three-parted, the divisions broadly cuneate-oblong, variously cleft and divided into acute, serrate lobes; those of the involucres similar. Flowers two-thirds to 1 inches broad, on peduncles 4 to 10 inches long; sepals five, white, obtuse; stamens numerous, shorter than the sepals. Carpels numerous, forming an oblong to subcylindric head, two-thirds to 1 inch long and about one-half as thick.

Gray), which is frequent in sandy woods and thickets in the eastern states has silky hairy stems and tufted basal leaves with narrower divisions, white or greenish flowers about three-fourths of an inch broad and the head of fruit cylindric, 1 inch long or often longer and one-fourth to one-third as thick.
