Great Britain, and only occurs here in small quantity ;. absent from 

 Ireland. 97. Ben Nevis! (Woods), and the neighbouring Glen Spean 

 mountains! 94. Ben Avon! 92. Ben-na-Bourd ! 49. Above Cwm 

 Idwal!; also reported from Snowdon. Recorded by Hudson from 

 Westmorland (v. c. 69), on the mountains above Ambleside (Hel- 

 vellyn is the most likely s]3ot). There is a cultivated specimen from 

 Kew Gardens, probably obtained through him, dated 1781, in Herb. 

 Smith, and annotated — in Smith's handwriting — " muscoides D. 

 Don " ; another, apparentl}'^ wild, in the Edinburgh Herbarium, 

 labelled "Westmorland"; and a third, from Dickson's Herbarium, 

 in Babington's set at Cambridge, collected by liis uncle, Thomas 

 Gisborne (no date), from the same county. These last two are 

 scrappy, and barely determinable ; but I passed them as being 

 apparently correct. The Kew Gardens example is untypical, and 

 will be mentioned again below. In Scotland it ranges from over 

 4400 feet down to 8400 feet and probably less ; the English and 

 Welsh localities are lower. Northern and Arctic : — Scandinavia, 

 Faeroes, Iceland, Spitzbergen, Greenland, and the Rocky Mountains. 



S. ixcrRTiFOLiA D. Don, /. c, p. 428. >S'. groenlandica Engler,

 tosa, var. incurvifoUa Bab. — This is endemic in Ireland ; the special 

 Saxifrages of that counti-y belonging to this section have strangely 

 little in common wdth those of the Pyrenees. I have only seen one 

 authentic specimen, which was sent by D. Don in 1826 to William 

 Peete, w^hose collection is now in the possession of Mr. S. H. Biek- 

 ham (see Journ. Bot. 1916, 189) : it was gathered late (in fruit) and 

 agrees well with both my wdld and cultivated plants. The hgure 

 {E. B. S. 2909) looks much coarser and more hairy, and seems to be 

 a young state of the rather variable S. liirta Sm. ; which accounts for 

 Syme's being misled, as these two species are totally unlike. Nor is 

 >S'. incurvifoUa a variety of >S'. cespitosa, as Babington suf)posed ; for 

 it stands the hardest winters of Surrey and Somerset quite well, 

 whereas >S^. cespitosa will not live out of doors, with me, and has to be 

 raised afresh every year from seed, under glass, at Edinburgh. They 

 are also very difc*ent in habit, colour, fohage, inflorescence, and 

 clothing. The Kew Rockery plant, as Mr. Williams informs me, just 

 matches my own ; most likely it came from the garden at Trinity 

 College, Dublin, where Mackay's roots from Kerry are, or used to be, 

 grown. 



Very rare. Kerry : Brandon Mountain !, chiefly at or near the 

 summit, but in 1902 I found a fine tuft at 1200 feet or less; 

 Beeowen Mountain, north of Sneem, R. W. Scully ; Macgillicuddy's 

 ]{eeks, M. C. Hartl Galway : Muckanaght, Twelve Bens, H. C. 

 Hart I It is likely to occur on the Galtees, Co. Tipperary. The 

 leaves are usually not incurved. 



S. ciEa':xLAXDTCA L. There is no specimen in Herb. Linn. ; and 

 this may partly account for the prevailing confusion regarding it. 

 Linnaeus himself can hardly have seen a livinr/ plant, if any ; and his 

 citation from Dillenius changes " cauUcuUs valde foliosis " into 

 " niiiUhii.s.'''' Ati'ain, liis shoi-t diagnosis: — " Saxifraga foliis caulinis
