Spikelets stalked, arranged in a loose open panicle, subcylindrical 
or slightly laterally compressed and biconvex, open during flower- 
ing, each containing 2, or, more rarely, 1 or 3, perfect florets, of which 
the lowest is sessile and the uppermost stalked, sometimes with 1 or 2 
Btalk-like rudimentary ones above the perfect florets or floret. Glumes 
2, unequal, both shorter than the floret, concave, not awned, 1- or 
imperfectly 3-ribbed, scarious. Pales 2; the lower one concave, keeled, 
rounded or truncate and erose-denticulated at the apex, not' awned^ 
3- to 7-ribbed, with the ribs not extending to the apex, parchment-like' 
with a broad scarious apex; upper pale lanceolate, truncate or emar- 
gmate, 2-ribbed. Lodicules 2, lanceolate. Stamens 3. Styles 2, very 
short, terminal; stigmas plumose, protruded at the sides of the flower 
between the basal margins of the pales. Caryops free, glabrous, obo- 
vate, laterally compressed, not furrowed. 
The name of this genus of plants is derived from the Greek word, mri/3p««c, an
