speciCvS thougli the}- be, as Aira alpina, Cochlcafia alpina, 

 Saxifraga hirta and 6'. groenlandica- These are confined to 

 and most characteristic of our scattered mountain-groups, and 

 are clearly remnants of an ancient flora. Why should our 

 mountains be deprived of the credit thereof? 



On the following page (xlv.) there is a list of the plants of 

 this group which descend in Ireland to, or almost to, sea 

 level. This is a very imperfect list. It should contain also 

 Saxifraga oppositifolia, Arctostaphyllos Uva-ursi, Isoetes laatstris 

 and Carex aqicatilis. These all descend to sea-level in several 

 places in Donegal, and the last three elsewhere in Ireland. 

 These facts I have recorded in a paper on altitudes^ which has 

 been largeh' made use of, I am pleased to observe, in this 

 volume— all except Carex aqicatilis, which was not then known 

 as an Irish plant. And these facts are duly recorded in their 

 proper place under the plants themselves in the bod}' of the 

 work. To these maj^ also be added several of the Donegal 

 Hieracia. Carex aqiiatilis is found onh' at low levels. At 

 Doochar}' Bridge, in Donegal, two forms of this sedge are almost, 

 if not quite, within the influence of exceptionally high tide. 



In the list of Scottish (and Intermediate) type plants (p. xlvi.), 

 there should be included several Hieracia. H. Schmidtii is of 

 this type, according to the editors' subsequent classification. 

 This genus is especially well represented in West Donegal 

 over a district extending Irom Sheephaven to Donegal Bay. 

 Several of them occur along the rivers at low levels, and they 

 especially predominate (as at Carrick) in the lowest reaches 

 along the immediate banks or margin of the water, giving one 

 far more the impression of, and associating with, Scottish tj'pe 

 rather than Highland type plants. In this list of Scottish 

 type, an asterisk plant like Myrrhis odorata is out of place. 

 It is certainly not a native. 



From the Atlantic type list (p. xlvii.), two very important 

 plants are omitted ; the Irish Spurge and the Killarney Fern. 

 Nor can I find them claSvSified in any of these preliminaiy 

 analyses. Both are subsequentl}" classified as Atlantic. The 

 latter of these two was similarly unaccountably omitted in the 

 original edition.
