IvIONOECIA TRIANDRIA. 
587 
glaucous, perennial, sheath at base open, shorter than the internodes. Floiv- 
ers in a large terminal pyramidal panicle, the lower branches generally by 
threes, the upper lanceolate. Flowers sterile and fertile intermingled, the 
upper florets generally sterile. Of the sterile floret glume 2-valved, valves 
equal, lanceolate, slightly mucronate, nerved, serrulate near the summit; 
filaments 6, very short; nectaries 2, minute. Of the fertile floret valves 2, 
unequal, lanceolate, mucronate. Style 1, longer than the interior valve of 
the corolla. Stigmas 2. Seed oval, glabrous. 
This species is more common than the preceding, and grows in similar 
situations; its leaves are harsh and coarse, eaten, I believe, by no animal, 
perennial, and of a dull glaucous colour. 
Flowers April — May.

This species is said by Dr. Baldwin, to be very common in the vicinity of 
Savannah. A small, creeping, jointed grass, floating whenever the soil on 
which it grows is overflowed. I have had no opportunity of examining it 
when in flower, nor of ascertaining whether our Southern plant is really the 
species described by Michaux. In habit and appearance it is totally unlike 
the two preceding species.
