140 The Irish Naturalist. [June, 



Coasts," next claimed attention, and yielded two interesting 

 plants wliicli apparently escaped the keen ej^e of that observer 

 — Osmmida regalis, growing in grand tussocks amid a jungle of 

 reeds and willows, and Pinguicula hisitanica, here only a few 

 feet above sea-level. A long da}- w^as spent on the grand cliffs 

 from Balh'vo3de to Bunmahon, and thence up the Mahon 

 River to Kilmacthomas. 



Next morning I started w^ork at I^ismore, explored the fine 

 wooded glen there, and worked down the Blackwater to some 

 miles below Cappoquiu. Potamogcton nitens, new to District 

 II., is plentiful in the river. On the banks above Cappoquin 

 I gathered a peculiar Nasturtium, which Mr. Bennett names 

 A^. barbara:deSi Tausch, = A'', amphibiiim x sylvestrc. As both 

 parents are known to grow about this portion of the Black- 

 water, the occurrence of the hj-brid is not unlikely. A plant 

 which is apparently the same, though unfortunately immature, 

 I had previously gathered b}^ the Shannon, on the I^eitrim 

 bank below Carrick. As A^. sylvestre is one of our rarest Irish 

 plants, and according to our present knowledge confined to 

 the Blackwater, Nore, Barrow and Erne, its extension to the 

 Shannon basin would be important, and I trust that some 

 botanist will take the hint supplied hy the h3'brid, and search 

 for it there. In the salt marsh below Cappoquin Cerastiiwt 

 holostcoidcs, Fries, a giant variety of C. triviale, was found in 

 its second Irish station. About Cappoquin, and indeed at 

 every town I visited in Waterford, Festuca Myuros grew. It is 

 a grass that has been overlooked in man}- districts of Ireland. 

 Heavy rain overtook me on my way to Cappagh. I gathered 

 Galium Mollugo on the railway bank there, and succeeded in 

 turning up one or two calcicole sj)ecies on the limestone — - 

 Orchis pyramidalis and Geranium lucidum. But the limestone 

 valley of the Blackwater is so choked with non-calcareous 

 debris from the hills on either side that the calcicole flora of 

 Co. Waterford is reduced to some half dozen species. 

 Thoroughly soaked, I took train at Cappagh for Dungarvan. 

 A 6-o'clock start next morning enabled me to skirt round 

 Dungarvan Harbour and examine the Conigar before taking 

 the morning train to Dublin. The Conigar is a strange sand- 

 bank i-^ miles long and often only a stonethrow wide, w^hich 

 almost cuts Dungarvan Harbour in tw^o. Cuscuta Epithyviu77i
