RANUNCULACE^. 3 



Floating leaves are occasionally produced, at least in some of the 

 stations, but there seems to be no other important difference in our plants 

 of this species. 



4. R. peltatus Fries. 



Lakes, pools, and slow streams ; common in Down, less frequent in 

 Antrim and Derry. Fl. mid. May till mid. Aug. 

 Down— BaUycroghan near Bangor; Flor. Belf. Magherascouse. Mon- 



lough, and TuUycaime ; T.H.C. Downpatrick, Ballynahinch, 



Saintfield Lakes, Hillsborough Park, and in the Lagan near 



Dromore; S.A.S. Dundonald ; R.L1.P. 

 Antrim— Canal near Lisburn, Portmore, several places in Lough Neagh, 



Lough Mourne, and abundant in the lower Bann ; S A.S. 

 Derry — Lough Beg near Toome ; T.H.C. River Bann ; S.A.S. 



First recorded as Irish in Flor. Belf., 1863. The Dromore plant is 

 rather curious, and may be R. elongatus Hiern. 



5. R. flultans Lamh. 



Deep, quick-flowing stream — very rare. Fl. June till mid. Aug. 

 Antrim — Plentiful in the Sixmilewater close to Dunadry station, and 

 lower down at Muckamore, also a little distance above where 

 the river empties into Lough Neagh ; S.A.S. The only Irish 

 station. 

 First found in 1865, in the river above Templepatrick, where it was 

 plentiful for some years until destroyed by bleachworks. Our plant 

 differs in appearance, both from English R.Jluitans, and its var. Bachii. 

 From R. penicillatus, which is abundant in the same stream, it is at once 

 distinguished by its smaller, more abundant flowers, with numerous 

 petals, and the hard rigid stems and leaves, with short stout segments. 

 The R. fiuitans of Flor. Ulst. was R. penicillatus. 



6. R. bederaceus Linn. 



Shallow pools, and wet, plashy ground, especially near springs and 

 moving water — frequent in Down, Antrim, and Derry. Fl. May — Aug. 



Sect. II. — Terrestrial, and sub-aquatic. 



7. R. sceleratus Linn. 



Stagnant ditches and muddy pools, mostly near the sea— common on 

 the Down coast, scarce in Antrim, and rare in Derry. Fl. June — Aug. 



8. R. flammula Linn. Lesser Spearwort. 



Marshes and wet pastures, generally distributed throughout the dis- 

 trict. Fl. June — Aug.
