Root annual ? Stem about two feet high, branching. Lower leaves two 

 to four inches long, oblong, lanceolate, deeply sinuate. Flowers in an ob- 

 long terminal panicle, female florets in the circumference, hermaphrodite in 

 the centre, all white. Involucrum many leaved, imbricate ; leaflets linear, 

 lanceolate or subulate, appressed ; female florets a little longer than the in- 

 volucrum, very slender, with the border slightly three-cleft. Stamens none. 

 Style setaceous. Stigma simple. Hermaphrodite florets with the corolla 

 shorter than the female, border five-cleft. Anthers as long as the corolla. 

 Style as long as the stamens, two-cleft. Stigmas glandular, obtuse, erect. 

 Seeds all fertile, oblong, angled, hairy. Receptacle naked, convex, dotted.
