RWS. 
First record in 1825: Mackay Cat. 
While this handsome perennial is frequently seen in 
demesnes and about houses in the county, it is included in 
the Kerry flora solely on the strength of its standing around 
the Killarney Lakes, where it is thoroughly established and 
has been known to occur for well over a century.

The extreme rarity of this plant in Kerry and its seeming 
absence from the greater portion of the county is very 
difficult to account for. A large area in north Kerry and 
extensive tracts about Killarney and Kenmare, appear to 
be especially favourable to the growth of this calcicole 
species ; it is reported, moreover, from all the adjoining 
counties, and has been gathered by the writer in West Cork 
not far from the Kerry boundary on several occasions.
