LIST OF SPECIES. 



Arranged for the most part after the 1th Edition of the London 

 Catalogue of British Plants, 1881. 



[Plants certainly not native are marked thus * ; those possibly introduced t ; 

 and those probably introduced J]. 



Ranunculace^. 



Thalictrum majus (Sm.), var. a. (Bab. Man.) — Eare. Only seen on 

 Groat Island and at Grubbaroe Point, Kesh. Two or three speci- 

 mens. 



T.flavum (Linn.) — Rare. On Killygowan Island, Upper Lake. 



Anemone nemorosa (Linn.) — Common. 



Ranunculus pseudo-fluitans (Syme). — In the river at Belleek under 

 the bridge. This is ■]irQhdh\j R. peltatus (Fries.), yox. penicillatus of 

 the Lond. Cat. But in the case of the Batrachian Ranunculi, I 

 hesitate to identify the synonyms. After a careful examination 

 of the British Museum series, I was much puzzled with some 

 varieties. 



R. heterophyllus (Fries.) — "Wet ditches on Devenish Island, &c. 

 These specimens somewhat resemble R. haudotii (Godr.). 

 \_R. eonfusus (Godr.) — An imperfect specimen gathered in a drain 

 one mile east of Crum Castle has been doubtfully referred to this 

 variety by Professor Babington ; but before extending the range 

 of a plant so rare in Ireland,* and usually found on the coast, 

 better specimens should be procured. At present it is included 

 under R. heterophyllus. ~\ 



R. hederaceus (Linn.) — By no means common. Noticed three miles 

 north of Enniskillen, on the east side, in 1881. !Not seen in 

 1882. 



R. flammula (Linn.) — Common. 



it. lingua (Linn.) — By the lake one mile north of Enniskillen. 



Plentiful. 

 \fR. axiricomus (Linn.) — Probably escaped notice, owing to its early 

 flowering.] 



R. acris (Linn.) — Common. 



R. repens (Linn.) — Common. Very luxuriant among the ruins on 

 Devenish. 



R. hulhosus (Linn.) — Certainly not common, and only observed at 

 Crum Castle.
