1900.] Hart. — Remarks 07i Cyhele Hibcniica. 35 



Beforeleaving the subject of the headquarters of boreal groups 

 of plants in Ireland, I have a few more words to say. Even 

 though there be a superiority^ in species in the Scottish group in 

 the north-east, the superiority is often the other way in the 

 abundance of individuals, which is a surer criterion, perhaps, 

 than scattered remnants of a failing or at any rate a rare flora. 

 This would apply to Primus Padus, w^hich the editors represent 

 as *' apparently decreasing" ; it is locally common in Donegal, 

 even abundant in several places ; to Ligustiaiyn scoticum^ 

 much commoner from Inishowen to Dunfanaghy ; to Lobelia 

 Dortviaima, " apparently decreasing" in the north-east ; to 

 Carex limosa and C filiformis ; but more especiall)^ to the High- 

 land group, such as Saxifj'agastellaris, S. oppositifolia, Saussicrea 

 ulpina^ Arctostaphyllos Uva-ursi{no\. seen in Antrim since 1837) 

 Salix herbacea^^ Ca?-ex rigida, and Isoetes lacustris, which are, 

 considering their requirements, fairly frequent, and some 

 even common, in Donegal ; but of rarity greater or less in the 

 north-east. 



If I were to select places in Ireland, conveying an idea of 

 the most northern (Highland) assemblages of plants, I would 

 place them in the follo"wing order, premising that there is a 

 long gap between the first two and the following habitats : — 



1. Slieve League in Donegal. 



2. Ben Bulben, Co. Sligo ; and the groups (Anna Coona, 



Truskmore, &c.) around. 



3. Muckanaght, Co. Galway, 



4. Brandon, Co. Kerry ; or Maamturk (Maumeen), 



Galway. 



5. Bulbein Mount (Inishowen). 



6. Ben Evenagh, Derry ; or Reeks (lyough Googh), Co, 



Kerr>\ 



7. Nephin or Croaghpatrick, Co. Mayo. 



The remainder — Antrim Glens, Wicklow, and Mourne 

 Mountains — never show such pleasing groups of alpines as these 

 do. I have not been careful to make out the totals. I speak 

 rather from the memory of the general facies of the flora in 

 these places, several of which disclosed their botanical secrets 

 for the first time to the present WTiter.
