Root perennial ? Stem two to three feet high, branching from the base, 
glandularly hairy, and very scabrous. Leaves of the root distinctly petio- 
late, with the petioles dilated at base, coarsely toothed ; of the stem some- 
what amplexicaule, acute, the veins all pellucid. Flowers in a compound, 
terminal panicle. Involucrum many leaved, (nearly one hundred) imbri- 
cate, cylindrical ; leaves linear, acute, viscid, pubescent, with the margins 
membranaceous. Florets of the ray about twenty, lanceolate, nerved; 
style scarcely longer than the tube ; seeds oblong, and excepting at the base 
glabrous ; exterior pappus a marginal cup, entire ; the interior pappus want- 
ing. Florets of the disk tubular, five-cleft, strongly nerved along the mar- 
gins ; stamens scarcely longer than the corolla. Seed hispid, exterior pap- 
pus composed of many membranaceous scales, the interior scabrous, red- 
dish brown. Receptacle deeply celled. 
Grows on the sand ridges near the ocean, and in dry pastures. 
Flowers October. 
The two preceding species differ in habit from this genus and the C. Sca- 
bra very much, in the structure of the seed and pappus. If the double or 
exterior pappus should be found to form permanent generic distinctions, 
and to unite those species which in habit, symmetry and character agree, 
this plant must be separated from this genus. It may be distinguished by 
the following character : 
CALYCIUM. Involucrum imbricatum, cylindricum. Anther ce basi 
nudae. Semina radii glabra, cupula coronata; disci hirsuta, pappo duplici, 
exteriore membranaceo polyphyllo, interiore piloso scabroj Receptaculum 
favosum. 
The first seven species of this genus, together with the C. falcata, form a 
very natural group, though the two first are marked with strong peculiarities. 
The two last differ in habit, and have also characteristic distinctions, which, 
with the increasing accuracy of the science, may cause them to be removed 
from this genus.
