Spica staminifera solitaria erecta cylindracea longo-pedunculata 
ebracteata ; spicis pas ternis remotis folio-bracteatis, supre- 
.ma ovata subsessili, in longis laxifloris exserte-pedin- 
culatis erectis ; fructiba tri aticis ovato-conicis ore integris 
nervosis subobtusis, i in spicam supremam multo majoribus et lon- 
gagbus aggregalis, squamam ovatam cuspidatam superne multo 
supera 
Culm 12-16 inches high, erect, slender, coed scabrous on 
the edges, leafy towards the base, with long and leafy bracts ; 
staminate spike single, erect, short, ‘abide pedunculate, having 
oblong and obtusish scales brown on the edges; pistillate spikes 
three, remote, leafy-bracteate, the highest nearly sessile and ovate 
close-fruited, the two lower oblong, distant, loose;flowered and 
exsertly pedunculate ; stigmas three; fruit ovate, conic, rather 
obtuse, epi at orifice, on the upper spike closer, larger, and 
much longer than the ovate and cuspidate scale, on the lower 
spikes loose sid a little longer than the scale. 
Augusta, Ill, Dr. S. B. Mead. Though related to C. conoi- 
dea, Schk., it is very different, and appears to be a new species. 
It is singular i in the different size of the fruit on the same plant, 
‘being much larger and longer on the upper spike.

Spica staminifera unica (plures? ) pedunculata longo-cylindracea 
bracteata, squamis denis lanceolatis longo-setaceis ; _Spieis pistil- 
liferis ternis vel juater gis Cj 
inferioribus | J latis exser S, Superiori- 
bus. subsessilibus ; fructibus tristigmaticis ovatis conico-rostratis 
nervosis bidentatis, squama lanceolata scabro-aristata brevioribus. 
Culm 20 inches or more high, triquetrous; with long leafy bracts 
surpassing the culm ; staminate spike slender, long, with long and 
slender bristly scales ; pistillate spikes 3-4, erect, cylindric, 14-2 
inches long, the two lower long pedunculate and exsert, the up- 
per sessile, all long leafy bracteate ; stigmas three; fruit ovate, 
conic-lanceolate, scabro-rostrate, round-triquetrous short two tooth: 
ed, sometimes teeth a little elongated ; scale lanceolate, awnlike, 
scabrous, longer than the fruit. 
Georgia, Dr. Cooley. I referred to this locality under C. ms- 
rata, but, as my friend John Carey, Esq. suggests, the plant dif 
fers too much-from that species. The fruit of C. mirata is | 
and wide bifurcate, while this is short two-toothed ; the scale | 
the former ren the fruit, while this surpasses the fruits 
mirata too the fruit is longer and more slender than on this. 
The fertile spikes on both are large, but are far Jessthan on C. 
gigantea, Rudge and Muh.
