An annual, herbaceous, slender plant, of about one foot, or a foot ad a half 
in height. Stem branched, especially upwards, in a dichotomous manner, 
branches pubescent. Leaves distant, the lower ones 3 or 4 inches in 
length, oblong, rather narrower towards the base, when they become semi- 
amplexicaul, throughout their whole length sinuato-pinnatifid; the seg- 
ments rounded, and more or less toothed: the upper leaves (mostly at 
the dichotomies of the branches) much smaller, toothed and lobed at the 
margin, waved and subtortuose, amplexicaul, broad and almost auricu- 
lated towards the base, all of them rather dark green, and very minutely 
pubescent, on the under side whitish and somewhat cottony. lowers of 
a moderate size, pure white. Involucre hemispherical, composed of se- 
veral linear-lanceolate, imbricated, erect, pubescent scales, the outermost 
of which are the smallest. Receptacle flat, punctated, naked in the 
centre, near the margin having a circle or single series of upright, gla-— | 
brous, chaffy, linear-oblong, denticulated scales, nearly canal in heel , | 
to those of the involucre. 
F ce ets, a few of the larger ones on the outside of the chaffy fe of the 3 
receptacle, but the greater number within them, tubular in the lower half, 
above divided into two very unequal ligulate lips; of these the outer one — 
is much the largest, ovato-oblong, more or less recurved, and obscurely 
3-toothed at the extremity, pure white; the interior one small, revolute, 
ligulate, at first white, at length transversely wrinkled and horn-colored. - a
