Root annual? Stem erect, three to five feet high, branching towards the 
summit, branches angled, somewhat viscid. Leaves alternate, sessile, large 
lanceolate, acute at each end, serrate, pubescent. Flowers in axillary and 
terminal corymbs, female florets in the circumference of each capitulum, 
very numerous, hermaphrodite in the centre few, rarely exceeding five, all 
purple Involucrum many leaved, (sixteen to twenty,) imbricate ; leaflets 
ovate, acute, pubescent, with the margins membranaceous. Female florets 
with the corolla slender, tubular, minutely five-toothed. Stamens none. 
Style longer than the corolla, two-cleft ; germ oblong ; seed oblong, cylin- 
drical, pubescent. Pappus hairy. Hermaphrodite florets funnel shaped, 
with the border five-cleft, somewhat expanding. Stamens longer than the 
corolla, purple. Germ very short, thick. Style as long as the stamens, 
two-cleft. Seed probably abortive. Receptacle naked, slightly convex, 
dotted. 
This species, and those that are strictly allied to it, are remarkable for 
the strong and to most persons disagreeable aroma, which is emitted from 
every part of the plant when bruised. 
Grows very abundantly in ditches and damp places, both in brackish 
and in fresh soils. 
Flowers August — September.
