Culms erect, three-sided, leafy, jointed, smooth, from four to 

 five feet high, angles sharp, between the joints fistulous. Leaves 

 of the root as long" as the culm, smooth, except that the mar- 

 gins are a little hispid, slender considering their great length, 

 those of the culm from five to eight, sheathing-, shorter than 

 those of the root. Umbels the terminal one decompound, 

 those only from the exterior axills compound. Involucre of 

 the terminal umbel, from three to four-leaved, about as long 

 as the umbel, leaf-like ; the axillary umbels have no involucre, 

 or, at most, a very trifling one. Flowers sub-solitary, ches- 

 nut-coloured. Calyx none. Corol; petals four. Style un- 

 divided, with a permanent conical base. Stigma entire, 

 acute. Bristles, six permanent ones surrounding the germ. 

 Seed a little compressed, crowned with a large brown, 

 spongy, conical body, the base of the style. 



Obs. There is frequently a very slender male flower with- 

 in the large or inner glume of the corol ; it consists of one- 

 glume or scale, and three stamens. The plant is so very coarse 

 that cattle will not eat it.
