This excursion (August 1908) had as objects the examination of 
plant associations and to see the rarer species so characteristic of this 
district. In Connemara the submerged and reed-swamp Vegetation 
of the numerous lakes occur with “Flachmoor” dominated by Rhyn- 
cospora alba in wetter places, and by Molinia coemlea var. depau- 
perata in drier parts; in the latter Erica Mackaii is an element. 
On the drier hillsides and knolls of metamorphic rock, the prevailing 
Vegetation is heath pasture or heath moor with Ulex gallii conspi- 
cuous, associated with Daboeocia polifolia and other Ericaceae. The 
woodlands occur on rocky islands or in sheltered ravines; they 
consist of a dense growth of dwarf trees (1—1,5 metre high) and 
include Quercus sessilißora, Pyrus aucuparia, Ilex, Taxus, etc. with 
dwarf moor-shrubs and a true woodland flora ( Primula acaulis, Hy- 
menophyllum tunbridgense, Listera cordata, etcO These woods are 
regarded as a higher stage in the succession from the heaths. In 
comparing the Vegetation of Connemara with N. W. Scotland, 
it is noted that while peat is being rapidly formed in West Ireland, 
denudation exceeds growth in N. Scotland. 
In the carboniferous limestone region of Southern Galway and 
Cläre, there is an extensive plain of limestone “pavement” with 
deep fissures containing a rieh Vegetation. Bold terraces rise from 
the plain to the flat-topped hills, again with “pavements”. The alti- 
tude rarely exceeds 30 M., yet Dryas octopetala is locally dominant. 
While the Vegetation is mainly “calcieole” it includes distinct “calci- 
fuge” species (e. g. Calluna). Woodland is scantily represented and 
Corylus, Crataegus, Fraxinus, are conspicuous with a wood-under- 
growth; one wood had Quercus peduncidata and Fraxinus more or 
less co-dominant, and the view is expressed that the oak type has 
been derived from the ash wood by accumulation of humus and 
washing out of lime, this being confirmed by other plants of the 
undergrowth. W. G. Smith.
