heavy dykes and on tlieir banks occurred Ruppia maritima, Scirpus 

 taberncemontani, Carex acuta, Rumex hydrolapathum, Potamogeton 

 pectinatus, P. piisillKS, Juncus glaucus, Lycopus europceus, Typha 

 latifolia, Utricularia vulgaris, Alisma ranunculoides, Poa aquatica, 

 Ranunculus lingua, Myriophyllum verticillatmn, Sium angustifoliimi, 

 Carex remota, C. stricta, and C. paniculata. Of this interesting 

 assemblage of plants, some of which are very rare, the only record 

 I find in the "Oybele" is that of Rumex hydrolapathum, noticed at 

 Clonee by Wade. At the shore at Olonea may be seen Glaucium 

 lutemn. Polygonum raii, Convolvulus arvensis, and Senebiera didyma. 

 This latter species has as much claim, or I should be inclined to 

 say, even more claim to be regarded as native than Senebiera 

 coronopus on the south coast of Ireland, so far as external appear- 

 ances go. Further south I met with nothing of interest till I 

 reached the lighthouse. Between that and the Coastguard Station, 

 Helminthia ecMoides occurs, and here, as elsewhere, through the 

 day, the prevalence of Geranium dissectum was noted. It is pro- 

 bably native in this part of Ireland. From this I obtained a boat 

 across the harbour to Dungarvan, the dirtiest and most disrepu- 

 table-looking town in Ireland. 



August 4. Having taken a boat for Helvick Head, five miles 

 off, the outer and southern point of the harbour, I left Dungarvan 

 early. On the way I landed at the Cunnigar, a long spit of sand 

 stretching up from the southern side to the northward. Juncus 

 acutus, Polygonum raii, and Artemisia absynthium, were observed : 

 the rush has previously been noticed here. At Helvick Head, 

 where the coast becomes steep and mountainous in character, I 

 met with Inula crithmoides and TrifoUum arvense, as also some 

 upland species, Solidago virgaurea and Molinia ccerulea. A mile 

 southward, Osmimda regalis and Senecio sylvaticus were noticed, 

 and Rubia peregrina is frequent along this coast. Equiseium maxi- 

 mum and Carduus pycnocephalus are also frequent. Inula crith- 

 moides was met with all along to Ardmore. At Mime Head (a 

 great resort for cormorants) TrifoUum arvense occurs again ; and 

 Torilis nodosa, a rare species, is very frequent. Foxglove and oak 

 occur along these steep headlands in profusion, the latter in its 

 stunted native form. Beta maritima is also a prevalent plant ; at 

 Mime Head, too, I found a steep bank decorated throughout with
