HORTUS GRAMINEUS WOBURNENSIS. 361 



FESTUCA elatior, var. sterilis. Barren-seeded Tall Fescue. 



Specific character : Panicle directed on one side, upright ; spike- 

 lets mostly awned, the outer one cylindric. Hort. Gram. 

 Fol. 255. 

 Obs. — It greatly resembles the Festuca praterms. It is larger 

 in every respect ; flowers eight or ten days later. The panicle 

 oi the pratensis is upright at first, afterwards drooping; while 

 the panicle of the elatior is drooping at first, and afterwards 

 upright : spikelets of a green and purple colour, cylindric, 

 generally awned ; leaves rougher and less pointed than those 

 of the Festuca pratensis. 

 Native of Britain. Root perennial, fibrous. E. Bot. 1593 ; 



Curt. Lond. 6, t. 7 ; Flo. Ger. Bromus littoreus. 

 Experimefifs. — At the time of flowering, the produce from a 

 black rich loam is —

The proportional value in which the grass of the 

 flowering crop exceeds that at the time the seed 

 is ripe, is as 5 to 3. 



The produce of latter-math is —

The grass, at the time of flowering, affords more nutritive matter 

 than that of the latter-math, in the proportion of 5 to 4 ; but the 

 grass of the latter-math contains more nutritive matter than that 

 at the time the seed is ripe, in the proportion of 4 to 3.
