400 feet ; northern slopes. 

 Carex dioica. 



350 feet ; Carrigan Head. 



Eadiola millegrana. 



Sagina subulata. Yery abundant on sea cliffs at about this height 

 and lower. 



Juniperus nana. Probably occurs higher also, but I have no note of it. 



Ophiogiossum lusitanicum. Same form as that of Horn Head, Brandon 

 Head, and Sybil Head. Called by Syme 0. folyphyllwrn, but is 

 not "polyphyllous." At lower levels round the base occur 

 commoner species ; on the sea cliffs Crithmiim maritinmm, Ilex 

 aquifolmm, Adiantum capillus veneris; and inland, Carex limosa, 

 C. ])anic%data, Mimulus hiteus, Rubus idmus, Hypericum elodes, 

 II. andrososmum, and several gregarious bog plants found every- 

 where at low levels. 



In the foregoing sketches there are many additions to the flora of 

 the county Donegal. Others which do not there appear will be given 

 in the list at the end of this report. Amongst these, two, Sieraeium 

 aryenteimi. Fries, Carex Iceninyliauseniana, Weihe, are additions to the 

 flora of Ireland, and Carex aquaiilis, W., has only just been added to its 

 flora by Mr. Stewart. I will now enumerate the rarer species met with, 

 with their habitats. A few, now first recorded, which belong to other 

 parts of the country, may be included. Commoner species will not, un- 

 less presenting some point of peculiar interest, be alluded to here. 



Thalictrum alpinum, Linn. Slieve League, above Lough Agh, from 

 1550 to 1310 feet above sea level. Found also on the Bluestack 

 mountains, and at the Poisoned Grlen in Donegal. 



Ranunculus heterophylhis, Bab. Bundrowes bridge, near Bundoran,^ 



in ditches leading to the river. 

 M. baudotii, Godron. By a little stream at Kildoney point, N.W. 



from Ballyshannon. 

 R. pseudo-fluitans, Syme. Biver Eske above Donegal ; river Erne ; 



Bundrowe's river near Bundoran. 

 R. sceleratus, Linn. Shore S.W. from Donegal. 

 \R. linyua, Linn. Recorded by Mackay from the shores of Lough 



Eske, apparently an error. Not yet found in Donegal.] 

 Trollius europ^us, Linn. In several places along the river Finn, on 



both banks between Drumbo and Cloghaun bridge, especially on 



the left bank immediately below this bridge, at the water's edge. 



This is the second Irish locality, the other occurring also in 



Donegal. 

 Nymphcea alba, Linn. Far commoner than Nupliar lutea, Linn., 



which, however, occurs in lakes near Pettigo, Carrick, &c. &c.
