Iribe iv. PHLEiNEiE. Inflorescence dense, spike-like ; spikelets 

 laterally compressed, i- flowered, sometimes with a rudimentary 

 flower as well ; outer glumes nearly equal, covering the flowers ; 

 styles long. 



9. Phleum (Timothy or Cat's-tail-Grass). Outer glumes boat- 

 shaped, their keels projecting into a point or very short awn ; 

 flowering glume shorter, very thin, awnless or with a very short 

 awn on its back ; pale very thin, sometimes with a minute bristle 

 at its base outside. (Name from the Greek phleos, a reed-like 

 plant.)

 slender awn on the bark ; pale wanting. (Name from the Greek

 lets laterally compressed, 2-flowered or more ; style none ; 

 stigmas very long. 



11. Sesleria (Moor-Grass). Spikelets in nearly sessile clusters, 

 crowded into an ovoid or cylindrical, spike-like panicle, the lower 

 with a glume-like bract at the base ; outer glumes nearly equal, 

 pointed ; flowering glumes 3- or 5-toothed at the top, the middle 

 tooth prolonged into a point. (Named in compliment to Leonard 

 Sesler, an Italian botanist.) 



B. Spikelets sessile in hollows of the rachis 



Tribe vi. Narde^e. Spikelets i-flowered, each consisting of 1 glume 

 enclosing a pale, 3 stamens, and an unbranched style. 



12. Nardus (Mat-Grass). Spikelets arranged alternately in 2 

 rows on 1 side of an erect, slender, simple spike. (Etymology of 

 the name obscure.) 



Sub-Order II. Eury anther. Flowers open; style short; 

 stigmas protruded near to the bottom of the flower. 



A. Inflorescence a panicle or raceme ; rachis with- 

 out lateral hollows 



Tribe vii. Oryze.e. Spikelets laterally compressed, 1- flowered ; 

 outer glumes wanting ; stigmas feathery. 



13. Leersia (Cut-Grass). Spikelets loosely panicled, consisting 

 of only 2 keeled glumes, the first rather broad, with 2 nerves on 

 each side, the second much narrower, with only 1 faint nerve on 

 each side. (Named in compliment to J. D. Leers, a German phar-
