Habitat. — Lofty mountains of Scotland, in Angus-shiie, Aberdeen- 

 shire, and norlli of Locli Lomond. — Mr. G. and D. Don. 

 Perennial. 



Of this plant but little more than the above description appears to be 

 known. Smith speaks of it as being " a very distinct and elegant 

 species, according to Mr. Don, whose description and characters," he 

 further adds, "1 have adopted;" and Mr. \\\ Wilson, in Hooker's 

 British Flora, says, " The recurved points of the segments of the leaves 

 may possibly distinguish this as a species ; but at present I think its 

 claims very doubtful." Such also appears to be the opinion of De 

 Candolle. 



15. S. caspi'tosa, Linn (Fig. 695.) Tufted Alpine Saxifrage. Stem 

 at the top crowded with from three to nine-cleft petiolated leaves, the 

 lateral spreading branches, with three-cleft leaves, the lobes elliptic, 

 lanceolate, obtuse, or slightly mucronated ; scape slightly leafy, from 

 three to nine flowered ; calyx of obtuse segments ; petals obovate or 

 oblong, obtuse, with three palmated veins. 



a, compacta. Leaves closely imbricated ; scape from one to two 

 inches high.

Roots fibrous. Stems trailing with distant leaves, but crowned with 

 a more or less densely crowded and imbricated tuft of leaves, from the 

 midst of which arises the solitary scape, and laterally, or trailing leafy 

 spreading branches; in |3. they are short and erect. Leaves of the 

 stem on flat somewhat channeled footstalks, of greater or less length, 

 and more or less hairy, cleft into from three to nine elliptic lanceolate 

 obtuse lobes, spreading, or in y. incurved, never pointed, as in S. 

 hypnoides ; sometimes the apex is terminated by a raucro, but it differs 

 in no respect from the hairs in other parts of the leaf, and the lobes are 

 more or less ribbed, the lateral ones with two, and the middle with three
