Hart — On the Flora of Soutli -West Donegal. 463 



Rumex hydrolapathuin, Huds. In several places from one to two miles 

 up tlie right bank of the Erne from Ballyshannon, and again at 

 "Cliff" nearer to Belleek. The only localities in Donegal. 



Oxyria reniformis, Hook. Slieve League, from 1550 to 1000 feet 

 above sea level. The second locality in the county; found by me 

 previously at the Poisoned Glen. 



Polygonum mviparum, Linn. Slieve League, at about 1300 feet above 

 sea level in one place only. The second locality in the county ; 

 found previously by me at Bulbin Mountain in Innishowen.

 tween Donegal and Ballyshannon ; near Ballyshannon to north- 

 west ; between Ballyshannon and Bundoran. 

 \Parietaria diffusa, Koch. Walls of Culmore Fort, Dean Gwyn.j 



-j^Salix pentandra, Linn. Abundant in upland districts, especially 

 about Pettigo, Donegal, and Ballyshannon ; also along roadsides, 

 and so often used for holding bog ditches together, that it is 

 hopeless to determine whether it is native or not. My impression 

 is that it belongs to the country, but has been long utilized. It 

 is quite characteristic of some streams, as between Pettigo and 

 Lough Erne, where it is 25 to 30 feet high.

 Hall ; sea cliffs, Slieve League, Malinbeg, and Killybegs to

 3Sydrocharis morsus-rance, Linu. Near Pettigo, Miss Young ; but 

 whether in Donegal or Fermanagh I have not as yet ascertained.
