﻿130 GRASSES OF SCOTLAND. 



in being of smaller growth ; the stem on the upper part more or less 

 rough and angular, especially under the panicle ; upper leaf invo- 

 lute, rough on the outer surface, and the root fibrous ; — whereas in 

 Festuca duriuscula the stem immediately under the panicle is round 

 and smooth, the upper leaf mostly flat and smooth on the outer sur- 

 face, and the root is more or less creeping- (See Plate LVIII.) 



This grass grows naturally on rather dry sandy soils ; frequently at 

 an elevation of 4000 feet above the sea, and forms the greater part of 

 sheep pasture grounds in the Highlands. It is the favourite food of 

 sheep ; they prefer it to all other grasses, for although small it is very 

 nutritious. Linnaeus states that sheep have no relish for hills and 

 heaths that are destitute of this grass. The smallness of its 

 produce renders it entirely unfit for hay. It is a common grass 

 throughout Scotland, England, and Ireland ; also a native of Lap- 

 land, Norway, Sweden, Germany, France, Switzerland, Spain, Por- 

 tugal, Italy, Russia, Iceland, Siberia, Greenland, and North Ame- 

 rica. 



Flowers in the second week of June, and ripens its seed about the 

 middle of July.
