The dry weight of this species was not ascertained, be- 
cause the smallness of the produce renders it entirely unfit 
for hay. If the nutritive powers of this species be com- 
pared with those of the preceding, the inferiority will ap- 
pear thus :

The comparative degree of nourishment which the grass 
of the Festuca rubra affords, exceeds therefore that afforded 
by the F. ovina, in proportion as 11 to 14. 
From the trial that is here detailed, it does not seem to 
possess the nutritive powers generally ascribed to it ; it has 
the advantage of a fine foliage, and may, therefore, very 
probably be better adapted to the masticating organs of 
sheep, than the larger grasses, whose nutritive powers are 
shown to be greater : hence on situations where it naturally 
grows, and as pasture for sheep, it may be inferior to few 
others. It possesses natural characters very distinct from 
F. rubra .
