﻿140 GRASSES OF SCOTLAND. 



being very short and obtuse ; spikelets without footstalks, and of three 

 or four florets ; — whereas in A. arundinacea the ligule is very long 

 and pointed ; spikelets with footstalks and of only one floret. 



This grass, says Mr Sinclair, may justly be considered as the su- 

 gar cane of Britain, as it is remarkable for the large quantity of sac- 

 charine matter it contains. It must necessarily render the hay made 

 from this grass very nutritious, particularly when cut into chaff and 

 mixed with corn or common hay. It grows naturally on the drifted 

 sands of the sea- coast, where it is of great value in arresting and 

 collecting the spreading of the loose sand, forming an effectual 

 barrier to repel the encroachments of the sea. It is a frequent 

 grass along some parts of the sandy shores of Scotland and 

 Ireland. In England it occurs along the coast of Northumberland, 

 Durham, Cumberland, Lincoln, Carnarvon, Cardigan, Norfolk, Dor- 

 set, and Devon ; also a native of Lapland, Norway, Sweden, Ger- 

 many, France, Spain, Portugal, Italy, Iceland, and British America. 

 It has not been discovered in the United States. 



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

 end of August.
