Hart — On the Flora of Southern Donegal. 575 



Scrophularia aquatica, Linn. Eoadside from Pettigo to Lough Derg, 

 about a mile and a-half from Pettigo. Local in Donegal. 



Veronica montana, Linn. Thickets on the island immediately below 

 Cliff House by the Erne ; Brown Hall. Very local, and perhaps 

 confined to south-west of the county in Donegal. 



Lycopus europceus, Linn. Croaghlinn Lake, near Killybegs, and Broc- 

 kagh Lake. Yery rare in Donegal. 



:{: Origanum vulgare, Linn. By a ruined mill on the right bank of the 

 Erne about a mile below Cliff ; on an old wall at Brown Hall. 

 An addition to the Flora of the county. 



Calamintha officinalis, Moench. Plentiful at a limestone quarry close 

 to Abbey Assaroe, near Ballyshannon. This addition to the Flora 

 of the county is due to Mr. Allingham. The record opposite "11" 

 under this species in the Cyhele Eilernica belongs to C. clino- 

 podium. 



\ Verbena officinalis, Linn. I have already reported this species on 

 Miss Toung's authority. Last year I visited the place and found 

 a compact little colony of this species by the road-side close to 

 Termon M'Grath's Castle. It is very rare — one other locality (?) — 

 in Ulster. 



Chenopodium bonus henricus, Linn. Killybegs. 



Polygonum raii, Bab. Coast of Boylagh promontory, north-west of 

 Ardara, in several places. 



^Fagopyrum esculentum., Linn. In a field with vetches, Moynalt, near 

 Laghy.] 



CalUtriche autumnalis, Linn. Cloonea Lake, near the coast, north- 

 west from Ardara. 



Euphorbia exigua, Linn. By a ditch near Grreencastle, sparingly, and 

 probably accidentally introduced. — "W. E. Hart. 



^Eumulus lupulus, Linn. jS'ear Carrick, below the bridge over the 

 Aughra river ; quite at home in a native-looking situation. 



TJlmus montana, With. Apparently native about Brown Hall, and 

 in the limestone glens of Moynalt, near Laghy. 



\8alix fragilis, Lian. By the Termon river above Pettigo ; by a 

 small stream above Carrowkeel in Fanet. 



8. pentandra, Linn. Near Pettigo, by the Termon, I saw a tree 

 30 feet high, with a stem 15 inches in diameter. 



S. herbacea, Linn. Slieve-a-Tooey ; Alt Mountain, near Ardara; 

 Aghla Mountain, at Finnstown.
