ON THE FLORA OF NORTH-WESTERN DONEGAL. 107 



Saxifragacece. 



Saxifraga umbrosa, L. Locally abundant. Errigal ; Muckish ; 

 Slieve Snacht West, and the Poisoned Glen. Also 

 naturalized and growing freely through the w^oods at 

 Glenalla. Descends to about 500 feet in the Poisoned 

 Glen, and reaches the summit of Errigal (2466 ft.) 



S. stellaris, L. Local. Muckish ; Dooish ; Errigal ; abundant 

 on Slieve Snacht W., and in the Poisoned Glen. 



8. hypnoides, L. Singularly rare in Donegal, and possibly 

 introduced in the one locality where I have met with it, viz., 

 amongst rocks, &c., almost at sea-level at the Little Bms, 

 Ballyvicstocker Bay ; I have observed it there for upwards 

 of ten years. Inula Helenium (a very doubtful native) 

 grows not far off, and the station is somewhat unusual ; 

 nevertheless, I am inclined to think the Saxifrage is 

 indigenous. 



S. oppositifolia, L. Very rare. In the Poisoned Glen, in the 

 two deepest gullies on the southern side, in profusion. I 

 have explored the western Lmishowen Mountain without 

 success, but it is recorded on good authority as growing 

 on Bulbein Mt. 



S. tridactylites, L. Macamish Pt., RathmuUan ; Mr. T. Batt. 

 [S. sarmentosa, L., is well established at Fort George, Eath- 

 muUan.) 



Chrysosplenium oppositifolium,lj. Not unfrequent. Little Bins, 

 &c. F. 



UmbellifercB. 



Hydrocotyle vulgaris, L. Common. F. 



Sanicula europaa, L. Frequent. F. 



Eryngium maritimum, L. Local. Melmore Pt.; Leenane ; 

 Horn Head ; Ballyvicstocker ; Doagbeg ; Dunaff and 

 Dunree. F. 

 [Carum Carui, L. Carrablagh, near the house. Introduced. F.] 



Helosciadium nodijiorum, Koch. Frequent. F. 



H. inundatum, Koch. Frequent. Kindrum; Fallaneass 

 Lake. F. 



jEgopodium Podagaria, L. In most of the gardens or pleasure 

 grounds through the county, and no doubt formerly 

 introduced; but now a troublesome and ineradicable 

 weed. F. 



Bunium flexuosum, With. Common in Fanet, &c. F. 



Pimpinella Saxifraga, L. Rare about Rossnakill and Tamney. F. 



CEnanthe Phella)idnum, Lam. Very rare ; ditch by the roadside, 

 between RathmuUan and Ray. 



CE. Lachenalii, Gmel. Rare ; Horn Head, near the bridge ; 

 Mulroy Lake, at Bunlinn. 



Haloscias scoticwn, Fries. This plant is characteristic of the 

 Donegal maritime cliffs ; I observed it in the following 

 localities this year (1878): — Dunaff Head and cliffs of Erris ; 

 Fanet Point ; Shores of Mulroy at Glinsk, and Ballyhoor- 

 iskey ; Melmore Point end at Gortnaloghogue ; Horn Head
