included, for such an arrangement cannot stand. Like S. S/eniber(/ii, 

 it varies somewhat ; but ^'. /iirfa Sm. is the only one of our plants 

 ■which can reasonably be confused with it, when dry, and they are 

 easily separable, when growing. It flowers, on an average, three 

 weeks earlier than S. hirta and S. Sternhergii, in cultivation. 



Very rare and local in our Islands. Wales : — v. c. 49 Carnarvon, 

 in and above Cwm Idwal; on Snowdon, and in the adjacent C wm Glas. 

 Scotland : — reported from Ben Lawers, but the only alleged specimen 

 which I have seen was AM-ongly named. Ireland : — Kerry, very rare 

 on Brandon Mountain, at about 2800 feet! Cairn Tuhol I, Aug. 17, 

 1852, Herb. Edinburgh; collector's name not given, but I think that 

 the handwriting is I. Carroll's. AVithout inflorescence ; the habit and 

 leaves are, however, quite characteristic. Also recorded from Slieve 

 Mish — named b}'- Engler, and likely enough to occur there; but 

 Mr. Scully's gathering, as represented in Herb. Druce, is a mixture 

 of ^S". hirta Sm. and (I think) ^S. inci/rri folia. Galwav :- — On one of 

 the Twelve Bens, 1882, H. C. Hart\ this is a stunted state, like 

 that figured in Eiiglish Botany, ed. i., as S. cespitosa ; it was so 

 naiued by Mr. Baker. Mayo : — Croaghmore Cliffs, Clare Island, 190^, 

 M. LI. Praeger ! Abundant here, froiu 1200 down to 150 feet. This 

 lias larger petals than the Welsh plant, of a purer white, not so 

 distinctly 3-veined, and less decidedly orbic\ilar, on first expanding. 

 S. rosacea is a native of Germany ; Bohemia and Moravia ; the 

 Faeroes ; Iceland ; and the Arctic regions. 



Ohs. — In Mr. F. J. Hanbury's herbarium there is a plant which 

 he gathered at Twll Du, v. c. 49 Carnarvon, April, 1882; the Kev. 

 A. Ley referred this to ^S'. decipiens. . It has broad petals and sepals, 

 very much like that ; but the leaves are glabrescent, narrower, acute, 

 and often bristle-pointed. I strongly suspect that it may be a hybrid, 

 perhaps S. platypetala X rosacea. 



S. HIRTA Haworth, Misc. Xat. 164 (1808) : Enum. Saxifr. 82 

 (1821). — Of this I have seen no authentic material. In the former 

 work he placed it between ^S*. qttinqufjida and S. patinata Sm. 

 {rosacea) ; in the latter between S. decipiens and *S'. platypetala, 

 with the remark : — *' S2)ecies bona, petalis orbiculato-ovatis albis tri- 

 plilinea virescente. An aflinior /S*. qiiinqjiefidce'^ Habitat in Europa, 

 non in Britannia" [in Misc. Nat.: — Habitat in alpibus Scotia?"]. 

 Under S. hihernica, fi. Smithii (Enum. Saxif. 29) he says: — ''Sax. 

 hirta, Engl. bot. t. 2991.— iV<?c nohis in Misc. nat. ; qute nonclum 

 spontanea in Britannia." He received it from Donn {not Don), and 

 it is the i)lant of Hort. Cantab, ed. v. 507 : but this is a mere catalogue 

 name, later (1805), and inadmissible. Judging by descri],tion and 

 sequence, it cannot be Gmelin's *S'. sponheinica. 1 think that this 

 name may safely be ignored ; and Mr. Williams concurred. 



S. HIRTA Smith, Engl. Bot. t. 2291 !, and Herb. Smith ! ; also of 

 1). Don, /. c. {non Haworth). *S'. hihernica Haworth. — Smith and 

 D. Don were quite right in separating this specifically frcmi aS'. deci- 

 piens, as I have proved by growing them both ; it would waste space 

 to give details now. Whether or no it occurs on the Continent 1 am 

 unaware. 1>. Don says tlial liis fnthcr's Sc()ilish s])ccimcns fi'om the
