364 HORTUS GRAMINEUS WOBURNENSIS. 



a considerable degree, that at least if it is not the sole cause, 

 over-richness, and great humidity of the soil and atmosphere, 

 greatly encourage the disease, as it often occurs, partially, to 

 many other grasses under such circumstances only. 



It comes into flower about the beginning of July, and the seed 

 is ripe about the first week in August. 



BROMUS littoreus. Sea-side Brome-grass. 



Specific character : Panicle branches wide-spreading ; spikelets 

 oval -spear shaped, sometimes awned, from 4 to 5-flowered. 

 Sm. Engl. Fl. 148. Festuca elatior. 



Obs. It may be only a variety of the Festuca elatior, but the 

 whole habit of the plant is manifestly different. The panicle 

 is perfectly upright before and after flowering, which distin- 

 guishes it from the varieties of Festuca elatior; the number of 

 florets in each calyx is less, the spikelets are oval-spear 

 shaped, those of the Festuca elatior cylindric. The leaves are 

 broader, more deeply striated, and rougher, of a finer dark 

 green colour, particularly in the spring. I never could find a 

 wild specimen of this grass. Hort. Gram. Fol. 259. 



Native of Germany. Perennial; growing on the banks of the 

 Danube and other rivers. Host. Gram. p. 7, t, 8.

When compared with the tall fescue, this species of brome is 

 found to be inferior in nutritive properties, and in the quality of 

 the herbage. The leaves are much coarser in every respect. It 

 cannot therefore be recommended for any agricultural purpose.
