Ivi INTRODUCTION. 
rivers of this Barony are numerous and fairly important, the 
greater portions of both the large Waterville and Caragh Lakes 
falling within its boundaries, while Derriana in the Cummeragh 
valley is nearly two miles in greatest length, and both Cloon- 
aghlin in the same valley and Coomasaharn at the foot of the 
Glenbeigh Mountains exceed a mile in length. Of the rivers, 
the Caragh and the Inny are the most important. : 
The only town in this extensive division is Cahersiveen with 
about 2,000 inhabitants. It is situated on a tidal river with a 
quay available for small coasting vessels, and communicates 
with the extensive Valencia Harbour where ships of consider- 
able size find anchorage. The railway from Valencia Harbour 
to Killorglin runs through this Barony for a distance of about 
25 miles, and although of quite recent construction the track- 
loving Linaria minor and Diplotaxis muralis have already 
succeeded in establishing themselves on its ballast. 
Owing to the absence of limestone formations, the calcicole 
group is poorly represented, only 24 species out of a Kerry 
total of 50 being known to occur here, and nearly all of these 
are confined to the sandhills around the coast. Woods, too, 
are few and insignificant except in the Glencar valley where 
several extensive tracts are found. 
The most interesting botanical localities are the lower 
portion of the Glencar valley and the neighbourhood of Caragh 
Lake. The first named yields Hieracium orimeles, Utricularia 
intermedia, Cephalanthera ensifolia, Juncus tenuis, Rynchospora 
fusca and Carex limosa, while in or about Caragh Lake occur 
Subularia aquatica, Galium erectum, Sisyrinchium augustifolium, 
Eriocaulon septangulare, Carex aquatilis, Naias flexilis, Isoetes 
echinospora, Nitella confervacea, N. translucens and N. flexilis. 
Only two plants native in Kerry are peculiar to Iveragh, 
Trifolium arvense and Chara contraria ; a third species, Sper- 
gularia rubra, unknown elsewhere in the county, is almost 
certainly introduced here. Other interesting species occurring 
in this division are— 
Glaucium flavum Saussurea alpina Juniperus nana 
Arabis ciliata Arbutus Unedo Malaxis paludosa 
Lavatera arborea Microcala filiformis Habenaria albida 
Asperula cynanchica Solanum marinum Carex punctata 
Inula Helenium Oxyria digyna Trichomanes radicans 
I. crithmoides Salix ambigua Asplenium viride 
With these are such characteristic Kerry species as Savifr 
eG : aga 
Geum, Pinguicula grandiflora and Bartsia viscosa. frag
