Culm IS 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. Brads setaceous. Sj/ikelets 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. 
StaiJiens 3. Sli/le 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. Baldicin ; New 
Orleans, Dr. Ingalls. 
Obs. The spikelets, nut, and bristles of our plant agree in 
every respect with a fragment of Schmmis fasciadaris from 
Michaux's herbarium. The description in his Flora Boreali' 
Americana applies minutely to our specimens, excepting the 
paragraph " setulis semine Icevi duple lo'ngiorihis : 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 ofMichaux, 
remarks that the plant had not fallen under his observation. 
I suspect that he has taken it for it. cymosa. I have not 
the means of determining whether our plant is the R.fasci- 
cularis of Vahl : it certainly does not agree in some respects 
with the detailed description of that species in Rcemer and 
Schultes' System a VegetabiUum. There is no specimen 
under the name of Schmius fascicidaris in the Muhlenber- 
gian herbarium. 
21. Rhynchospora paniculata. 
R. culmo triquetro ; paniculis numerosis, approximatis, inter 
dum geminatis ; spiculis oblongo-lanceolatis, ad ramulos fas- 
ciculatis ; nuce laevi, obovata, lenticulari, tuberculum subula-
