The Mourne mountains are poor in alpine plants, despite 

 the fact that over a dozen peaks exceed 2,000 feet in 

 elevation ; the dry massive granites are inhospitable, the 

 slates little better. The plants which are in our district 

 confined to the Mournes are few in number : 



Drosera intermedia. 

 Saussurea alpina. 

 Hieracium senescens. 



Hieracium argenteum. 



H. hibernicum. 



H. gothicum var. Stewartii.
