GRASSES OF BRITAIN. 195 



Calamagrostis Lapponica is distinguished from Calamagrostis Epi- 

 gegos in the hairs being shorter than their floret ; avm scarcely longer 

 than its floret ; — whereas in Calamagrostis Epigegos the hairs are 

 considerably longer than their floret, and the aicn extends nearly half 

 its length beyond its floret. 



Calamagrostis Lapponica is distinguished from Calamagrostis lan- 

 ceolata in the Jloret being about equal in length to the glumes ; hairs 

 shorter than their floret ; awn arising from a little beneath the centre 

 of its floret ;-— ^whereas in Calamagrostis lanceolata the floret is one- 

 third shorter than the glumes ; hairs longer than their floret ; aicn 

 arising from a Uttle beneath the summit of its floret. 



This grass grows in Ireland near Loch ]Seagh, and in other places 



in the county of Antrim ; but in no other part of Britain has it yet 



been discovered. It is a native of Lapland- 

 Flowers in Jime and July. Its agricultural merits probably rank 



with the preceding. 



The accompan}-ing figure was taken from a specimen gathered near 



Loch Xeagh.
