Very like the preceding species, but with rather pleasantly aromatic foliage. Stem smooth, much branched, one to two feet high. Leaves pinnate, twice or thrice divided into many linear lobes. Heads numerous, terminal, about three-fourths of an inch broad, on very slender, naked peduncles; rays ten to twenty, white, drooping as they mature, pistillate, fertile; disk-florets perfect and fertile, yellow, the receptacle at first rather flat but becoming conic and hollow; bracts of the involucre oblong, obtuse, green, with brown, scarious margins. Achenes short, three-ribbed, and without pappus.
Means of control the same as for Mayweed.
