28-i ON THE BIIITISH DACTYLOID SAXIFRAGES. 



original name for this variety), and by Dr. Planchon " spoiihemica" 

 are doubtful between this and the next. In Sir W. C. Trevelyan's 

 Feroe collection there is a sheet of specimens of a form which quite 

 corresponds with the Welsh and Irish examples just mentioned, and of 

 another allied form, more robust and more hairy, with larger flowers 

 and broader calyx-lobes. There is a characteristic specimen from Ice- 

 land in the Kew collection, from Mr. Paulsen. 



4. S. affiids of D. Don, as represented by Mackay's wild Irish speci- 

 mens, and figured in ' English Botany,' quite corresponds with the 

 specimen in Reich. Exsicc. 1888, of S. sponhennca, Gmelin, "e loco 

 classico " (Sponheim in the Palatinate), and the same form is given 

 as sponJiemica by F. Schultz (Exsicc. n. 67), and there are authentic 

 specimens of it under the name of sponJiemica, in Herb. Gay both from 

 Koch and Grenier ; and Gay refers to sponhemica specimens gathered 

 by himself, in company with Professor Babington and the Rev. W. W. 

 Newbould, on Snowdon. All these are unmistakably one and the same 

 plant. This variety is so widely spread in Britain that there is no 

 need to quote special stations, and I can only consider S. platypetala, 

 ' English Botany,' as another form of the same variety, with more 

 elongated, weaker stems, and unusually large flowers. This variety is 

 less robust than the last, both in the stems and leaves, usually gla- 

 brous, or nearly so, with the leaves of the shoots always without buds 

 in their axils, and usually spreading and cut down into three narrow 

 linear-ligulate acute lobes, and lanceolate acute calyx-teeth. Adding 

 affinis to it, I should consider the 8. eiiJiypnoid^s, a. platypetala of 

 Syrae to be just parallel to the sponhemica of Koch and Kyman. A 

 series of specimens, labelled sponhemica by Sternberg, all come within 

 the range of the British variety as here understood. An original ex- 

 ample of S. palmata, Lejeune, Fl. Spa. p. 191, is just the average 

 British form. From tlie Continent I have seen it from Belgium, 

 France (the Jurassic border only, not the interior or Pyrenees), the 

 Palatinate, and Bohemia, which, in fact, are just the tracts from which 

 Nyman reports it. The following is Gmelin's original account of the 

 plant in 'Flora Badensis,' vol. iii. p. 226 : — 



" S. sponhemica foliis radicalibus aggregatis, sessilibus, cuneatis, quin- 

 quepartitis, laciniis rectis, aristatis, caulinis tripartitis, rameis setaceis, 

 integris, adpressis ; caule erecto, glabriusculo, raraoso, stolonibus rep- 

 tantibus.
