Plant annual. Stem about 2 feet high, hispid, often coloured, trichoto- 
mously divided towards the summit. Leaves alternate, on very short peti- 
oles, crowded near each division of the stem, elliptic, coarsely and obtusely 
serrate, pubescent on the upper surface, hairy underneath. Flowers in the di- 
visions of the stem, the fertile sessile, the sterile in small spikes intermingled 
with them. Sterile florets. Calyx 1-leaved, tubular. Corolla 5-petalled, 
petals lanceolate, white, longer than the calyx inserted into its base. Stam- 
ens 10. as long as the corolla. Fertile florets. Calyx 5-leaved, persistent, 
hisped, 2 large, 3 smaller. Corolla 0. Styles 3, 2-cleft. Stigmas simple. 
Capsules hispid, the cells separating when mature, each 2-valved, 1 -seeded. 
Grows in all cultivated land, very common. 
Flowers June-— October. 
Nutt. 2. p. 225. 
Plant annual, when bruised aromatic. Stem 1 — 2 feet high, pubescent, 
tomentose when young, branching irregularly. Leaves on short petioles, 
oblong-lanceolate, sometimes obtuse, light green and somewhat smoother in 
the upper surface, hoary underneath. Flowers in terminal clusters, the ste- 
rile spike growing from the midst of the sessile fertile flowers. Calyx of 
both tomentose. Styles 3, each compoundly dichotomous. Capsules very 
tomentose. Cells l-seeded_ 
This species agrees in many respects with the C. Capitatum of Mich, and 
the C. Ellipticum of Nutt, and differs slightly from both. Not having speci- 
mens of each, I have hesitated where to place it. 
Grows in the pine-barrens near Columbia, Mr. Herbemont. 
Flowers in the summer. 
Leaves oval-lanceo 
late, entire, when old 
obtuse, stellularly to- 
mentose, pale under- 
neath; flowers termi- 
nal, clustered, sterile 
and fertile intermin- 
gled. 
Ellipticum? Nutt. 
C. foliis ovali-lance- 
olatis, integerrimis, se- 
nioribus obtusis, stella- 
to-tomentosis, subtus 
pallidioribus; floribus 
terminalibus, congestis, 
foemineis masculisque 
immixtis.
