Hart — On the Flora of Southern Donegal. 573 



'^Samlucus ehilus, Linn. Eoadside near Donegal, on the way to Lough 

 Eske ; at Brown Hall ; waste ground by a farm-house south of the 

 Erne in the southern corner of the county. 



Galium horeale, Linn. Broken limestone ground, opposite Bally- 

 shannon, on the south side of the river in the townland of 

 Carrickbeg. 



Valeriana officinalis, L., var. samlucifolia. On limestone shingle by 

 the Erne, below the bridge at Belleek. 



Knautia arvensis, Coult. Fields on the east side of the Donegal road, 

 about two miles from Ballyshannon. Very rare in Donegal. 



\_Lonicera xylosteum, Linn. Has been known to grow in the woods at 

 Brown Hall for a century, and there is no tradition of its having 

 ever been introduced; but I presume this must have been the 

 case.] 

 Gnaphalium sylvaticum, Linn. Pettigo ; between Lough Finn and 

 Grlenties. 



Filago germanica, Linn. Sand-hills at Magheragh. 



Anthemis nohilis, Linn. By the Erne, right bank below cliff ; by the 

 stream a little above Killybegs. 



[^Matricaria parthenium, Linn. Abundantly established on the bridge 

 at Belleek.] 



Saussurea alpina, D. C. Alt Mountain, near Ardara, at 1350 to 

 1400 feet. 



Centaurea cyanus, Linn. About Moynalt and Brown Hall, Laghy 

 and Ballintra. 



XCarduus crispus, Linn. By the Erne below the Belleek bridge, 

 amongst waste heaps. 

 Sieracium argenteum, Fr. Moynalt, near Laghy, in a river glen. 

 Determined by Mr. James Backhouse. 



a. gothicum, var. By the Mourn ebeg river, at the boundary of the 

 county south of Stranorlar. This is the same variety as that from 

 Carrick river, which Mr. Backhouse considers "like S. norvc- 

 gicum, Fr.," and with " heads far too numerous for gothicum.''^ 



S. gothicum, var. latifolium. Kiltooris Lake ; river at Ardara and 

 Glenties. 



S. iricum., Fr. By the Erne, on limestone near Ballyshannon. This 

 form is altogether inseparable from Backhouse's /? cermthoides, the 

 lowland form of anglicum. Specimens from the same locality have 

 received either name on different occasions. It is the only hawk- 

 weed I have met growing on bare, pure limestone rock. St* 

 John's Point. 



S. anglicum, Fr. Ardara.
