Hoot fibrous, perennial. Culm varying from 2 inches to 2 feet in 

 height, according to the soil in which the plant grows. Leaves 

 a little concave, striate, nearly equalling the culm; sheaths 

 somewhat distichous, pubescent on the margin. Umbel gene- 

 rally simple, consisting of from 3 to 4 rays each bearing a 

 spike, and a sessile intermediate one. Involucrum 3-leaved, 

 one of the leaves longer, and appearing like a continuation of 

 the culm. Glumes ovate, acute, brown. Stamens 3. Style 

 2-cleft, fimbriate. Seed obovate, compressed, naked at the base. 



Hab. In wet meadows, and sometimes on dry hills: in the latter 

 situation it seldom attains the height of a span. On the Island 

 of New-York. In Pennsylvania and New- Jersey. Muhlen- 

 berg. August. Apparently not distinct from the West-Indian 

 plant. 



24. S. spadiceus L. : culm compressed, nearly naked ; 

 umbel terminal ; involucrum rigid, 2-leaved, one of the leaves 

 longer than the umbel ; leaves subterete ; spikes ovate-oblong, 

 terete. Sp. pi, 74. JVilld. Spec. I. p. 305. Walt, Car.

Root a tuft of dense fibres. Culms cespitose, tenacious, about 

 2 feet high, nearly round below, but compressed above. Leaves 

 radical, about half as high as the culm, somewhat channelled 

 on the interior surface ; sheaths dilated, beardless at the throat. 

 Umbel consisting of several compressed peduncles, each bear- 

 ing several spikes. Sfiikes very closely imbricate, when old 

 cylindrical, brown. Glumes nearly orbicular, smooth. Sta- 

 mens 3. Style 2-cleft, distinctly fimbriate. Seed compressed, 

 striate, yellowish. 



Hab. In salt marshes. I have found this plant only on the edge 

 of the salt meadow at Hoboken, New- Jersey. In Pennsylvania.
