In the clefts of rocks, and on mountains, in Yorkshire, and several 

 parts of Ireland. 



Plentifully on a mountain called the Mangerton, county of Kerry, 

 2 miles from Killarney ; Dr. Molyneux ; on the mountains of 

 Sligo ; Mr. Lhwyd. Raii Syn. On Croagh Patrick, county of 

 Mayo, 2666 feet above the level of the sea. Mr. Lambert. Near 

 the lake of Killarney, in the greatest abundance ; also in Cork 

 and Kerry. Rev. T. Butt. In Thorp Arch woods, near Wetherby, 

 Yorkshire. Sir T. Frankland, and Dr. White. Betwixt Arncliffe 

 and Horton in Craven. Rev. W. Bingley. 



Perennial. June. 



About the size of the last, or larger. Leaves in large, rose-like, 

 perennial tufts, smooth, roundish-obovate, with strong, sharp, 

 cartilaginous serratures ; the base of each tapering gradually 

 down into a broad, flat, nearly smooth, ybo^sia/Ar, at first shorter 

 than the leaves, but subsequently becoming sometimes twice 

 their length. Common Jlower-stalk round, red and hairy, from 

 4 to 6 or 8 inches high. Panicle with several hairy, viscid, 

 racemose branches, each bearing 3 or 4 alternate flowers, not 

 forked like the preceding. Cal. small, reddish, obtuse, closely 

 reflexed. Pet. obovate-oblong, obtuse, pale flesh-coloured, 

 stained with yellow near the base ; more or less covered with 

 crimson dots on the disk. Caps, ovate, reddish, entirely supe- 

 rior, tipped with the short, nearly upright, styles. 



Mr. Don's variety /3, which I have also from Mr, Mackay, is very 

 unlike the original Linnsean specimen of S. punctata from Sibe- 

 ria. The latter belongs to a different section of the genus, having 

 the germen partly inferior ; the calyx broad and hemispherical at 

 the base, with broad, triangular, spreading or erect, not reflexed, 

 segments ; and nearly sessile stigmas. Morison's/. 17 is justly 

 excluded by Mr. Don from this variety, nor does it belong to the 

 true punctata; but rather to S. umbrosa, which is so common 

 in gardens, and bears, like many other mountain plants, even 

 the smoke of London, as its English name expresses. The leaves 

 in one of Mr. Mackay 's specimens, which may perhaps be Mr. 

 Don's y, have small, sharp, intermediate teeth, between the 

 coarse serratures. 



4. S. stellaris. Starry Saxifrage. 



Leaves elliptic-wedge-sliaped, coarsely serrated; taperinf^ 

 and entire at the base. Panicle corymbose, of few 

 flowers. Capsule superior.
