Somewhat like the Mayweed, but without its unpleasant odor and acrid juices. It is low, seldom exceeding a foot in height, some of its many branches decumbent, others ascending, very leafy, and finely hairy. Leaves sessile, one to three inches long, pinnate, once or twice divided, much less feathery than the Mayweed. Heads numerous, usually exceeding an inch in width, with ten to twenty white, spreading, two-toothed rays, pistillate and fertile; disk-florets perfect; bracts of the involucre are oblong, obtuse, hairy, with scarious margins. Achenes oblong, obscurely four-angled, crowned only with a minute border for a pappus. In some localities this is a worse weed than its ill-scented relative, and its achenes are a common impurity in those of grass and clover.
The same measures should be used for its control as for Mayweed.
