DESCBIPTIONS OF TRIBES AND GENERA. 119 



Species six, throughout Europe, especially in the 

 South, and in North Africa, one species in all temperate 

 countries. A. elegans Gaud, and A. caryophyllea L. (Fig. 

 59) are frequently cultivated for dry bouquets under the 

 false name of Agrostis elegans. Fiorinia Pari, is an awn- 

 less species. 



153. (152) Antinoria Pari. In general like the pre- 

 ceding, but the flowers are separated by a manifest 

 internode of the rachilla, and the flowering glumes are 



different. 



Species two, in Southwestern and Southern Europe. 



154 (152) Molineria Pari. Like the preceding, but 

 with the flowers projecting from the empty glumes. 

 Flowering glumes truncate or slightly toothed, awnless 

 or with short awns. 



Species three, Western and Southern Europe to Asia 

 Minor. PeribalUa Trim is a species with a short, two- 

 toothed flowering glume. 



155. (155) Achneria Munro (non Beauv.). Spikelets 

 small, in panicles ; flowers separated by a short inter- 

 node of the rachilla, somewhat shorter than the empty 

 glumes, often hairy. Perennial grasses. Leaves fre- 

 quently convolute. 



Species eight, in Southern and tropical "Africa {Eri- 

 aekne of Nees, in Flora Afric. Austr.). 



156. (153) Corynephorus Beauv. ( Weingcertneria Bern- 

 hardi). Grasses with the habit of Aira, but with ^ the 

 rachilla prolonged, and club-shaped awns with a circle 

 of short bristles at the point of articulation. 



Species three, in Europe. C. canescens Beauv. (Fig. 

 60) grows in sand fields ; it is a hardy but a poor pasture 



grass. 



157. (154) Deschampsia Beauv. Spikelets rather small, 

 two-flowered (rarely with an imperfect third flower) ; 

 panicle loose or compact ; florets separated by an inter- 

 node ; flowering glumes exceeding the empty ones ; awns 



slender. 



Species twenty, in all cold and temperate countries, 

 a few in the high mountains of the tropics. 



Sec. I. Campella Link (as a genus). Awns straight.
