19. Saxifraga Stellaris, L. 1, 2, 3. 4, 5. Northern and Central 

 Groups. This Saxifrage is found throughout Carnarvonshire, and advances 

 southwards to Cader Idris, and Plynlimmon, where its most southern known 

 station in Britain is on the head of the W3'e. Can it be realij' absent from the 

 Brecon Beacon range? Common northwards, in the Lakeland and Scottish 

 hills. 



20. Saxifrag-a csespitosa, L. 2. Northern Group. Very rare : 

 see Mr. Baker's paper on the " British Dactyloid Saxifrages," in the /oio-Ha? of 

 Botany, 1870, p. 281. Mr. Baker here states that he has seen one specimen only 

 of the Welsh plant, gathered by Mr. Wilson in Cwm Id wall in 1825. See, 

 however, Prof. Babington's Note, id., 1887, p. 281. I have never met with it in 

 Britain. Absent from Lakeland ; present northwards and westwards, on the 

 highest Scottish and Irish summits. 



21. Saxifraga decipiens, Ehrh. 2. Northern Group at Cwm Idwall. 

 Very rare : see Mr. Baker, I.e., p. 283. It is to be feared that these two Saxifrages 

 have become extinct in Carnarvonshire. I myself gathered the present plant 

 in TwU-duchasm in 1876, but I have not succeeded in finding it in two or three 

 subsequent visits. Absent southward ; westward, the South of Ireland presents 

 very nearly allied forms. See Baker, Journal of Botan;/, I.e. 



22. Saxifraga sponhemica, Gmel. 1, 2, 3, 4, 5, 6, 7. In every 

 clifiF I have visited of the Northern, Central, and Southern Groups. Forms which 

 must be referred to this name are so inextricably mixed up witii those referable 

 to the next, that I am at present unable to distinguish them ; but I have Mr. 

 Baker's authority for assigning some of our Black Mountain plants to "good 

 sponhemiea." Brecon or Glamorgan will be its southern limit in Britain. 



23. Saxifraga hypnoid.es, L. 1, 2, 3, 4, 5, 0, 7. Present in all 

 parts of Wales, Northern, Central, and Southern, in abundance; and, generally 

 speaking, far the most common form throughout Britain. In Carnarvonshire, 

 and T think in the Brecon Beacon, the relative frequency of this and .S'. sponhemica 

 is reversed, at least so far as the crags are concerned. Here the greater part of 

 the dactyloid Saxifrage one meets with must certainly be placed to S. sponhemica. 

 In the Black M(juntain S. hi/pnoides predominates. 



24. Galium boreale, i. 1,2,3,6. Northern Group at many stations : 

 Southern at one. This Bedstraw is thinly scattered among the Carnarvonshire 

 cliffs, and recurs on the Brecon Beacon range at more than one spot in very small 

 quantity. It is not recorded in Top. But. Ed. I., for the Central Group, nor have I 

 myself succeeded in finding it at Llyn Cau ; but it can hardly really be absent 

 from Cader Idris. It is more abundant northwards (Yorkshire, Lakeland, 

 Scotland) ; but Breconshire is its southern limit in Britam. 



25. Saussurea alpina, D. C. 1, 2, 3. Northern Group: on the 

 higher Carnarvonshire cliffs at 2,200ft. to 3,200ft. Still in plenty, but very 

 inaccessible, near the summit of Clogwyn-y-Garnedd ; also at Cwm Idwall, and n 

 fair plenty on Carnedd Dafydd. It appears to be more abundant in Carnarvon- 

 shire than in Lakeland, where it was long thought to be confined to a single 

 station ; but it has a wide distribution in the Scottish Highlands.
