Apparently very restricted in its range in Ireland, but often 

 separated with difficulty from robust states of -E". Tetralix, and 

 perhaps more widespread than would appear from the above records. 

 Not found in Great Britain, and on the European continent recorded 

 only from the mountains of Castile and Asturia in the Spanish 

 peninsula. The Irish plant was at one time erroneously considered 

 to be identical with H. Watsoni, a hybrid between H. ciliwris and 

 -E". Tetralix, which occurs in Cornwall. 



Discovered near Eoundstone previously to 1835 by William 

 M'AUa, by whom it was communicated to Mackay. Eirst published 

 in 1835 in the Companion to the Botanical Magazine (p. zj8).
