Mr. J. Ball's Botanical Notes of a Tour in Ireland. 29 



during an excursion from Dublii;' through the northern part 

 of the island in the summer of 1837 ; as also to notice the 

 discovery of two or three plants, which are, I beheve, new to 

 the British Flora. The neighbourhood of Dublin is princi- 

 pally rich in some of the m.ore local sea plants ; I may men- 

 tion as a station for several of these the south-eastern side of 

 the rocky point of Killiney Hill, A^ hich runs out towards the 

 small island of Dalkey. I have here gathered Inula (Lim- 

 barda. Hook.,) crithmoides, Lavatera ai'borea, Euphorbia port- 

 landica, Linum angusti folium, Statice spathulata, Daucus ma- 

 ritimus, &c. Further south, near Bray, Marrubium vulgare 

 may be seen more truly wild than it usually is in Ireland, ex- 

 tending for some distance along the shore, as also upon the 

 common near the town : on banks near the road, between 

 Bray and Enniskerrj^, Erodium moschatum appears certainly 

 indigenous, and near the latter village I have noticed Melissa 

 Calamintha (Calamintha officinalis, Hook.), and Polygonum 

 minus, Scirpus Savii, Habenaria chlorantha, &c., as also Ge- 

 ranium pyrenaicum certainly wild and veiy common. Erio- 

 phorum pubescens, which has hitherto been found in the boggy 

 ground just above the village, is, I fear, extirpated by drain- 

 age. In the sand pits on the hill by the Dublin road may be 

 noticed Festuca bromoides, and also a remarkable state of 

 Hieracium Pilosella, apparently intermediate between that 

 plant and H. Peleterainum, Merat., which latter is however by 

 many botanists considered a mere variety of H. Pilosella. 



In Glen Cree, a valley running from Powerscourt to Lough 

 Bray, I have gathered Carex IcEvigata, Senecio viscosus, Pin- 

 guicula lusitanica, Myosotis repens, Pyrus Aria, &c. ; and on 

 the mountains south of Glen Cree I have found a Leontodon 

 (Apargia, Hook.), to all appearance distinct from any recog- 

 nised British species. If it be possible to judge by mere de- 

 scriptions in this difficult genus, I should consider it to be 

 L. alpinum, Jacquin, (L. pyrenaicum, Gouan,) though in some 

 respects it approaches more near to L. hastile of Linnaeus. 



The neighbourhood of Powerscourt Waterfall is remarkably 

 productive in ferns ; in addition to the common species, there 

 are found herePolypodiumphegopteris, Nephrodium oreopteris, 

 Hymenophyllum Tunbridgiense and H, Wihoni (which latter
