Spikelets dimorphous, clustered on a unilateral spikelike pani- 

 cle, the outer spikelet of each cluster consisting of several glumes, 

 all empty ; the other spikelets containing 2-5 flowers ; empty glumes 

 linear or sublanceolate ; floral glume broader, membranous, 1-3- 

 nerved (rarely 5-nerved). mucronate or sometimes awned; jialea 

 with two ciliate nerves. Stamens 3. Grain adherent to the floral 

 glume and palea. 



There are 3 or 4 species with a wide range over the temperate 

 regions of the Old World, and one is now naturalized in several other 

 countries. It is remarkable for having the lower spikelets barren, 

 and the spikes are elegantly pinnate with empty glumes.
