Tribe YIL— AGROSTIDE.E. 
Spikelets open during flowering, arranged in a lax open panicle, 
or more rarely in a dense cylindrical spikelike panicle, laterally com- 
pressed, each containing a single perfect floret, sometimes with a 
superior rudimentary one, very rarely with 2 or more perfect florets. 
Glumes equal or unequal, at least one of them longer than the florets. 
Pales scarious, the lower one keeled. Stamens 3. Styles very short; 
stigmas 2, protruded at the base of the florets between the margins of 
the pales. Caryops subcylindrical or compressed, with a furrow line 
on the inner face, loosely covered by the pales. 
GENUS XF.-G A S T R I D I U M. Pal.de Beauv. 
Spikelets shortly stalked, arranged in a narrow compact dense lobed 
panicle with short lateral branches which are spreading during flower- 
ing and afterwards adpressed, laterally compressed, open during 
flowering, each containing a single perfect floret without the rudiment 
of a second. Glumes 2, nearly equal, both much longer than the 
floret, bluntly keeled, acute but not awned, swollen and ultimately 
indurated at the base, subscarious. Pales 2, very unequal, hyaline, 
the lower one very shortly bearded at the base, truncate and denticulate 
at the apex, with or without a bent dorsal awn ; upper pale very 
minute, with 2 keels. Lodicules 2, entire. Stamens 3. Styles 2, 
nearly sessile, plumose, protruded at the sides of the floret between 
the basal margins of the pales. Caryops glabrous, free, oval, slightly 
dorsally compressed, flat and with a shallow furrow on the inner face. 
The name of this genus is derired from the Greek words yatrriip and "dior, in refer- 
ence to a swelling on the glume.
