Plant annual. Stem about 2 feet high, hispid, often coloured, trlchotb- 

 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. F/ojrcrs 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-petaIled, 

 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.

Plant annual, when bruised aromatic. Stem 1—2 feet highj pubescent, 

 tomentose when young, branching irregularly. Leaves on short petioles, 

 oblong-lanceolate, sometimes obtuse, light green and somewhat smoother it 

 the upper surface, hoary underneath* Flowers in terminal clusters, the s e- 

 rile spike growing from the midst of the sessile fertile flowers. Cal]/^ o 

 both tomentose. Sti/Ies 3, each compoundly dichotomous. Capsules^ery 

 tomentose. Cells 1 -seeded. - u A 



This species agrees in many respects with the C. Capitatum of M»cn. an 

 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*
