stone rocks. Fl. mid. June till mid. Aug. Ranges from 600 to over 

 2000 feet altitude. 



Down— Poolagaragh south of Tollymore, 1793, and common on the 



Moume Mountains; Templeton. 1799. Shady cliffs on Slieve- 



na-Gloch, and many more of the Moume Mountains ; Wade 



Rar. Still frequent on the Moume range at elevations above 



^ 1000 feet. 



Derry — Rivxilets on the sides of Sawel, and abundant on the top of Dart, 

 also on Clontygeragh ; D.M. 



2. S. hlrculus Linn. 



Moory peat bogs— very rare. Fl. July and early half of Aug. 

 Antrim— In considerable abundance in an elevated moor near Dvmloy, 

 parish of Rasharkin, a little west of some low rocks called 

 "Cohinnen" and "Lough Rocks"; D.M. in Cyb. Eib. 

 {spec, in herb. Babington dated 1841). Rediscovered, by Rev. 

 S. A. Brenan, growing sparingly on swampy ground near 

 Lough Naroon, townland of Glenbuck, Rasharkin, July 31st, 

 1S84. Jour. Bot. vol. 22, 1884. Mr. Brenan's loc. is very 

 near, but not precisely the original station. Boggy, and 

 elevated plateau behind Garron Point ; R.Ll.P., July 8th, 

 1884. Jour. Bot. vol. 22, 1884. Mr. Praeger describes the 

 plant as plentiful here. The locality is about 14 miles east 

 of the original habitat. 



3. S. alzoldes Linn. 



Damp shady rocks — very rare. Fl. July and Aug. 

 [Down — " Rocks by the cataract at Donard Lodge " ; Flor. Ulst.'] 



This is a plant not readily overlooked, and usually abundant where it 

 occurs. It was not noticed by Mr. Templeton, or any of his contempor- 

 aries, nor yet by any recent botanist, and we conclude that it was not 

 native on Donard, but existed for a brief time as an introduced, ornamental 

 plant. This conclusion is fortified by the mineralogical instincts of this 

 species, as displayed in its Irish distribution. It seems to be confined, in 

 Ireland, almost, if not altogether, to limestone and its near ally (for 

 phytological effects) trap rock, and therefore not likely to be found on 

 grit. 



Antrim— Murlough; Miss Rineks in Flor. Ulst. Plentifully at Murlough 

 Bay near _ Fairhead ; D.M. in Flor. Ulst. In considerable 

 quantity in woody places amongst rocks by streams, and on 

 wet rocks by several streamlets on the north side of Tor Head : 

 T.H.C. 



4. S. liypnoides Linn. Mossy Saxifrage. 



Ledges of rocks, and more especially abundant on debris and under- 

 cliff — frequent, but confined to limestone and basalt, not found on sili-
