Hibernian. The result of garden culture, and especially 

 of raising the Irish Saxifrages froiia seeds, kindly sent to 

 me by Mr. Andrews, seems almost to warrant the union of 

 this and S. Gaum, as a single species only. The difficulty 

 is, that while S. hirsuta appears to pass into S. Geum, on 

 one side, it approximates very much towards S. umbrosa on 

 the other.

Area (9 10 11 12 13 14 15). 



Alien in Britain? Native Hibernian. The testimony 

 in support of this species being native in Heseltine Gill, 

 near Settle, is so strong that I should have been tempted 

 to treat it as such, if T had been enabled to give the geo- 

 graphical relations here with any approach to accuracy. 

 But, as yet, the locality has been visited only by collectors 

 of specimens ; so that I am quite unprepared to state the 

 region, zone, altitude, temperature, or other necessary in- 

 formation for the botanical geographer. If we allow this 

 Saxifi-age to be native in Yorkshire, the presumption is 

 increased in favour of some other habitats being also gen- 

 uine ; for instance, those of Taxall, in Cheshire, and Craig- 

 y-bams, in Perthshire. In reference to the Yorkshire lo- 

 cality, Mr. Tatham says, "I consider S. umbrosa really 

 wild here. It is met with in Heseltine Gill, which is a deep 

 ravine, at the foot of Pennighent and Fountains Fell.
