The -wide gaps in the range of this species in "West Ireland are 

 strikingly coiacident with the appearance of the limestone formation 

 in Kerry, Clare, Gralway, and Sligo. 



From 800 to 2000 ft. in Donegal ; sea-level to 2680 ft. in Mayo, 

 1750-2500 ft. in Tipperary, sea-level to 3370 ft. in Kerry, 

 500-2600 ft. in "Waterford (Sort). — A mountain plant in almost 

 all of its inland stations, but freely descending to the lowlands near 

 the sea lq the "West and South-"West. 



First definitely recorded for Ireland by Dr. T. Molyneux in 

 1697 and probably observed there some fifty yeais earlier, as the 

 plant is entered, without any locality, in Sow's Phytologia, ib^o. 



We cannot, with any confidence, separate the many Irish forms 

 of this variable species into the varieties seeeatipolia. Don and 

 PUNCTATA Don. "When a full series of Irish specimens is 

 examined the finest gradations may be traced from obovate to 

 orbicular in the general outline of the leaf and from crenation to 

 sharp serration ia the form of the margin. In no case, however, 

 •does the Irish plant exhibit the very blunt crenation and strongly 

 marked cartilaginous leaf margin which appears to be characteristic 

 of the Pyrenean, Spanish, and Portuguese S. umhrosa. In Kerry, 

 Connemara, and "Waterford the prevalent leaf-form is one with 

 strongly serrate margins, and truly crenate forms are very rare in 

 Ireland. In Sternberg's Supplement (Prague, 1831) to his Revisio 

 Saxifraga/rum many of the various leaf -forms of this species and of 

 jS^. Geum are excellently figured,
