Barrington — Report on the Flora of Lough Erne. 7 



[^Ranunculus ficaria (Linn.) — Escaped notice, probably, as in the case 

 of R. auricomus.'] 

 Caltha palustris (Linn.) — Common. 



C. radicans (Forst.) — In tolerable plenty on soft mud on the east 

 side of Devenish Island, near the ruins. When first seen, it 

 struck me as being a very unusual form of C. palustris, with 

 almost deltoid leaves, narrow non-contiguous sepals, and rooting 

 at the nodes. I have compared it with specimens from Porfar- 

 shire in the herbarium at Cambridge, and with the original figure 

 in the Linnean Society's " Transactions," vol. viii., p. 323. It 

 has been shown to Professor Babington, Mr. J. G. Baker, the 

 Eev. "W". "W. Newbould, and others, all of whom consider it to be 

 C. radicans. My specimens are not perfect — the sepals having 

 fallen off in the vasculum — but they were much narrower than 

 in ordinary C. palustris, and non- contiguous. 



*Aconitum napellus (Linn.) — Near Castle Hume, Lower Lake ; out- 

 cast from garden. 



Ntmphace^. 



Ntjmphcea alba (Linn.) — l^ot uncommon in various parts of the lake. 

 Nupliar lutea (Sm.) — Far commoner than the last. 



Papavekace^. 



'^'Chelidonium majus (Linn.) — On the walls of Crum Castle. Not a 

 single specimen of any species of the genus Papaver was observed, 

 thus confirming its known rarity in the west of Ireland. 



Ffmariace^. 

 [None of this family observed.] 



Cetjciper^,. 



Sinapis arvensis (Linn.) — Frequent. 



Sisymbrium officinale (Scop.) — On Devenish and elsewhere. 



S. alliaria (Scop.) — Not common. In the wood at Castle Hume, 



Lower Lake. 

 Cardamine pretensis (Linn.) — Common. 

 C. hirsuta (Linn.) — Common. 

 C. sylvatica (Link). — Frequent. 

 Barbarea vulgaris (Brown). — Occurs in several places. A specimen, 



with spreading and curved pods, gathered one mile north of 



Enniskillen, comes near B. arcuata (B,eich,), which ought to be 



looked for. 

 Nasturtium officinale (Brown). — Common.
