84 TRIANDRIA. MONOGYNTA, 
or emarginate, inner margin closely inflected, including _ 
the corolla, and the shorter membranaceous inner valve — 
, (almost after the manner of Nardus stricta). Corolla 2- 
valved, very thin and membranaceous. Masculine or neu- 
tral flower and calix smaller. Stamens 3. Styles 2, brown, 
plumose, and exserted. * : 
Collected by Dr. Baldwyn, on the sea-coast of Georgia 
v. 8. This species has very much the habit, and indeed 
the character of Andropagan. ot 
3. *rugosa. Culm erect, leafy; spikes cylindric, solitary, 
axillary, and proximate; joints of the rachis smooth, sub- 
~~ -semicylindric, tumid; outer valve of the hermaphrodite 
olla, flower transversely rugose,}3-valved; accessory flower 
mostly neuter, upon an emarginated pedicell. epee 
Culm erect, tall, smooth, and solid, deeply grooved at 
the commencement of the branches. Leaves rather short, 
scabrous on the margin and midrib; sheathes compressed, 
shorter than the internedes, in the stem leaves nearly 
open, and cloven to the base, with membranaceous mar- 
gins. Spikes 2 to 3 inches long, axillary, solitary, cylindric, 
approximating, furnished with cymbiform sheathes, as in 
the genus Andropogen; perfect and imperfect flowers in- 
clined to different sides of the spike, the latter pedicel- 
Jaie, mosily neuter; flowers and rachis entirely smooth, 
: articulations deeply excavated, closed conjointly by the 
_' compressed neutral pedicells, and the valve of the perfect 
__flewer. Outer valve of the hermaphrodite calix obiquery 
: = ovate, acuté, cartilaginous, externally marked with 2 or 
transverse rugose elevations, inner valve acute, coriace- 
_ ons, covered by the excavated arch of the rachis, and la- 
_ terally impressed by the coniiguous pedicell of the neu- 
_ ter flower; corolla 3-valved, exterior auxiliary valve, of 
neutral rudiment? nearly the length of the calix, proper 
_ corolla valves oval obtuse, considerably shorier than the 
_ Calix; valves of the neutral calix smoothand even, scarce- 
ly 1-tourth the size of those of the perfect flower. Sta- 
mens 3. pase 2, very short. a"

=. & This species appears to be Jess allied to Jnidropo- 
gon by character than the former, but possesses at the 
same time much of the habit of that genus, having axil- 
_ lary pedicellate, solitary spikes, of which there are fre- 
— guently 2 in the same sh-ath of the leaf; each of the 
spikes are also partly closed in a proper spathose acu- 
minate leat with membranaceous margins. This species 
appears to be very considerably allied, to the BR fascicu- 
_ ata, of Desfontaines as figured and’ described mm the
