Obs. This is, doubtless, the S. triglomerata, Muhl. and probably of Elliotl. 

 Whether it be Michaux'e plant is not quite so clear: and it certainly is not tho & 

 triglumerutti, of Pursh— if his description may be relied upon.

 row-linear ; spikes lateral and terminal, few-flowered, the lateral ones 

 on long peduncles ; glumes nearly smooth ; nut papillate. Beck, Bot.

Hoot perennial. Culm erect, 9 to 18 inches hi#h, leafy, slender, triquetrous,, 

 .striate, nearly glabrous below, roughish above. Leaves linear, narrow, somewhat 

 pilose, roughish on the margin ; sheaths pubescent. Fascicles few-flowered ; the 

 lateral ones usually 2 in number, on long slender peduncles, the lower ones pro- 

 ceding from a sheath near the base of the culm. Droits longer than the spikes,,

Hob. Serpentine ridge, West Chester : not common. Fl. June. Fr. July. 



Obs. 1 can discover no material difference between our plant and the S. ciliata. 

 iSU. aud Ell. of which I have received specimens from N. Carolina, from my valu 

 ed friend and correspondent, Mr. M. A. Curtis. The S. hirtella, Mx. which Muhl 

 ttberg thought might be the same, is a stouter and more hirsute plant, apparently 

 quite distinct. 1 suspect the 8. paucitlora, Muhl. is, in fact, the S. cMuta* of Mx. 

 TV7/M. Pers. Pttrsh, ice. and that th« S. pauciflora, of those last mentioned authors 

 (although the description does not suit,) may be intended for the S. oligantha, of 

 ;U#.and Elliott-—* very distinct species, with a smooth, polished nut. I have re- 

 reived the S. hirtella, and S. oligantha, from Mr. Curtis. Six or seven addition- 

 al species are enumerated in the U. States*
