Eubus saxatilis, Linn. Abundant and characteristic on the limestone 

 country south of Brown Hall. 



Rosa arvensis, Linn. Eoadside, near Tennon ; IVI'Grath's Castle, 

 below Pettigo ; and by the Temion river above Pettigo. 



Pyrus aria, Sm. ISTear Brown Hall, in several places. A hybrid 

 between this species and P. aucuparia was observed near Brovni 

 Hall, and on the Finn, near Cloghaun. I believe it is a, cultivated 

 form. 



MyriophyUum spicatum, Linn. Swampy place near the sea on the 

 north shore of Boylagh promontory, north of Cloonea Lake. 



Saxifraga stellaris, Linn. Mountains about Ardara and Slieve-a- 

 Toory. 



S. aizoides, Linn. Alt Mountain, near Ardara, abundant, from 1400 

 to 650 feet. This is the second locality in county Donegal. Mr. 

 Arthur Brooke, of Killybegs, who helped me much in the explo- 

 ration of this mountain, was the first to find this saxifrage. 



8. oppoutifolia, Linn. Steep banks close to sea level on the coast 

 between Slieve-a-Toory and Magheragh, forming the sward in 

 some places. 



8. tridactylites, Linn. Limestone ledges by the Erne, below cliff on 

 the opposite bank. This species, which is not rare on the larger 

 sand-hill districts by the coast in Donegal, seems seldom to occur 

 inland. In the south and midland counties it frequently appears 

 inland on old walls, &c., but not on the coast, as far as I have 

 observed. 



l^Sempervivtcm tectorum, Linn. Frequent in the district on cottages, 

 where it is planted both for the luck it confers, and for its medi- 

 cinal properties.] 



Sedum rhodiola, D. C. SHeve-a-Toory ; Ardara Mountains, &c. ; 

 grassy pastures at Dunmore Head, Ardara. 



Selosciadium nodiflorum, Koch. Croaghlinn Lake, near Killybegs ; 

 shore at "Wardtown, near Ballyshannon. 



Sanicula europcea, Linn. This frequent species is very highly thought 

 of as a cure for consumption. It is sold under the name of 

 " Sinicle " for this purpose in the town of Donegal and else- 

 where in "Ulster. 



(Ethusa cynapium, Linn. About Ballyshannon. 



Torilis nodosa, Groert. Appeared very sparingly as an introduced 

 weed at Greencastle, Innishowen. A specimen was sent me by 

 "W. E. Hart. 



Scandix pecten-veneris, Linn. Corn-fields near Ballyshannon.
