 renlform acutely crenate more or less hairy, footstalks linear 

 channelled, scape panicled, capsules superior. — a. leaves hairy

Mountains, in the south of Ireland. Fl. June. If. — This species has 

 the margin of the teeth cartilaginous, but less so than the two following. 



2. S. hirsuta, L. {hairy oval-leaved Saxifrage); leaves more 

 or less cordate at the base slightly hairy, footstalks linear, scape 

 panicled, capsule superior. E. Bot. t. 2322. 



Gap of Uunloe, near Killarney, Mr J. T. Mackay. Fl. June. 1^. — 

 Readily distinguished, Mr Mackay observes, from .S". Geum, by its oval 

 leaves, which are of a deep green colour. But my friend, the Rev. W. 

 T. Bree, who has cultivated and studied the Saxifrages very assidu- 

 ously, says that it is certainly a hybrid between the preceding and the 

 following. 



3. S. umbrosa, L. {London-pride Saxifrage or None-so-pretty); 

 leaves roundish-oval with cartilaginous teeth tapering gradually 

 into a broad footstalk, panicle small, capsule superior. E. Bot.

 fruitstalks elongated. Mackay. S. punctata, Haivorth (not Sm.). 

 — y. leaves oblongo-ovate glabrous light green with deep acute 

 serratures. Mackay. Rohertsonia serrata, Haivorth. 



Plentiful on mountains in the south and west of Ireland. This species 

 is found in woods at Wetherby and in Craven, Yorkshire, and about Edin- 

 burgh and Glasgow, but not really wild. FL June. "4. — Well known in 

 our gardens, even amid the smoke of London ; hence, and in conse- 

 quence of its beautifully spotted flower, it is called, with us, London- 

 pride ; in Ireland, St Patrick's Cabbage. 



4. S. stelldris, L. {starry Saxifrage); leaves oblongo-cunei- 

 form angulato-serrate scarcely petiolate, panicle subcorymbose 

 of ^Qw flowers, capsule superior. E. Bot. t. 167. — /3. leaves 

 quite entire. 



Sides of rivulets and wet rocks, in the mountainous parts of the north 

 of England, Scotland and Ireland. — /3. Rocks on Ben-Nevis, Mr. S. 

 Murray. Fl. June — Aug. If . — Stems short, growing frequently in tufts. 

 Leaves with coarse teeth ; in /3. quite entire, and thence having so dif- 

 ferent an aspect, that, at first sight, Mr Murray as well as myself con- 

 sidered it to be a totally distinct species. 



** Calyx spreading, half- superior. Scape with a head of flowers. 



5. S. 7iivdlis, L. {^clustered alpine Saxifrage); leaves obovate
