S. incurvifolia, D. Don, Trans. Linn. Soc. Vol. XIII. p. 423. 



S. crcspitosa, y iucurvifolia, Bab. E. B. S. No. 2909, and Man. Brit Bot cd. v. p. 134. 



Segments of the leaves incurved, sometimes obtuse ; sepals 

 rather obtuse. 



On Alpine rocks. Var. « on the summit of Brandon Mountain 

 and at Hag's Glen, Kerry, and on Galtee-more, Tipperary; also 

 said by Mr. G. Don to be found in the West of Scotland ; var. 3 

 and var. y on the summit of Brandon Mountain, with var. «. 

 Scotland (?) Ireland. Perennial. Summer. 

 Plant growing in lax tufts. Barren shoots 1 to 4 inches long 

 at the time the plants flower. Leaves with a broad petiole, expand- 

 ino- gradually towards the lamina, which is dilated and deeply 

 3-fobed, with the lateral lobes simple or 2- or 3-cleft, the lobes and 

 se-ments nearly parallel-sided almost to the apex, where they we 

 abruptly pointed. Leaves on the flowering-steins few, 3-clett. 

 Bracts elliptical, entire. Plowering-stem 3 to 8 inches high, 1- to 5- 

 flowered. Flowers \ inch across, white. Plant more or less thickly 

 clothed with gland-tipped pubescence. 



The S. aflinis is said to differ by having subulate sepals and 

 petals incurved at the sides; but specimens in the herbarium at 

 Kew, and in that of the Iinnsean Society, collected by Professor 

 Babington, appear to me identical with those labelled S. hirta, on 

 the same authority, and contained in the same herbaria. In the 

 Smithian herbarium, however, there is a plant, sent apparently by 

 Dr Mackav, which agrees better with the characters assignee to 

 S. aflinis, having the sepals narrower and the pubescence much less 



abundant than in the ordinary S. hirta. m 



Of var y I know nothing except from the plate in isng. 

 Bot. Suppl.," which is again given here. Professor Babington and 

 Dr. Mackay consider it a variety of S. caespitosa (S. dccipiens, 

 Ehrli.); Mr. Bentham and Mr. H. C. Watson regard it as a form 

 of S. hirta, and Dr. Walker Arnott is uncertain to which ot the 

 two it ought to be referred. If the drawing be accurate I think 

 there can be no doubt that it is rightly placed under S. hirta.
