* Root fibrous, annual. Stem ereet, 4 — 8 feet high, slightly angled, very 
glabrous, a little fistulous. Leaves alternate, ovate-lanceolate, acute at each 
end, ribbed, obscurely crenulate, 2 — 5 inches long, one to two and a half 
wide, on petioles 1 — 3 inches long, generally coloured. Floivers in large 
panicles axillary and terminal, the sterile more slender than the fertile. 
Florets all sessile, or on very slender pedicels. Sterile florets; calyx 5- 
parted (5-leaved?) segments lanceolate, acute, glabrous, the margins coloured 
(obscurely red;) corolla 0; stamens 5, as long as the calyx. Fertile florets; 
calyx 3-parted, persistent; corolla 0. Germ superior. Styles 0. Stigmas 
3 — 5, reflexed, almost plumose. Capsule ovate, 3 — 5 angled, agreeing in 
number with the stigmas. Angles obtuse or acute, slightly rugose, not 
opening. Seed ovate, compressed, glabrous, tapering at base by which it is 
attached to the base of the capsule. 
Grows in marshes and wet soils along the margins of our fresh water riv- 
ers, resembling very much an amaranth. 
Flowers October — November.

Plant large, erect, 6 — 8 feet high. Stem- thick,* fistulous, 'angled. Mich. 
With this species I am unacquainted. At least I have noticed but one 
species in our marshes, and as I felt some doubt where to refer it, I have 
described it with some minuteness. 
Grows along the marshes of our rivers from Canada to Florida. Nutt.
