Culm 18 inches to 2 feet high, obscurely triangular. Leaves narrow- 

 linear, shorter than the culm. Corymbs about 3, densely fascicled 

 and somewhat few-flowered ; the lower one subdistant, exsertly pe- 

 dunculate ; the two upper approximate, subsessile. Pedicels very 

 short. Bracts setaceous. S^nkelets oblong. Glumes ovate, carinate, 



with a long mucro ; the exterior shorter, obtuse ; the inner ones acute. 



Bristles 6, about half as long as the nut, minutely hispid upward. 



Stamens 3. Style bifid. Nut lenticular, ovate or round-ovate, smooth. 



Tubercle much compressed, with the base as broad as the nut, about 



half its length. 



Hab. In Carolina, Michaux ; Georgia, Dr. Baldwin ; New 



Orleans, Dr. Ingalls. 

 Obs. The spikelets, nut, and bristles of our plant agree in 

 every respect with a fragment of Schoemis fascicularis from 

 Michaux's herbarium. The description in his Flora Boreali- 

 Americana applies minutely to our specimens, excepting the 

 paragraph " setulis seminc Icsvi ditplo longiorihus : whereas 

 in his own plant, and in all the specimens I have examined, 

 the reverse is true, the nut being about twice the length of 

 the bristles. Elliott, who copies the description of Michaux, 

 remarks that the plant had not fallen under his observation. 

 I suspect that he has taken it for li. cymosa. I have not 

 the means of determining whether our plant is the R.fasci- 

 cidaris of Vahl : it certainly does not agree in some respects 

 with the detailed description of that species in RcEmer and 

 Schultes' System a Vegetabilium. There is no specimen 

 under the name of Schoe.nus fascicularis in the Muhlenber- 

 gian herbarium.
