This little weed is common in waste places and fields and along roadsides, almost all over the world. It is a branching annual, from one to two feet tall, with feathery light green foliage, cut into many long, narrow divisions, almost smooth, with a disagreeable smell and strong acrid taste. The many daisy-like flowers have heads about an inch across, with from ten to eighteen white rays and convex yellow centers. There is a picture of this plant in Mathews' Field Book.
SUNFLOWER FAMILY. Compositae.
There are a good many kinds of Chaenactis, the flower-heads with tubular flowers only, but in some kinds the marginal flowers are larger and have a broad border resembling a kind of ray.
