BOTANICAL NOTES

THE ARRIVAL OF EPILQBIUM NERTERIOWES CUNNINGHAM IN THE MOURNE AREA OF CO. DOWN

Under the name Epilobium nummulariaefotium the late R. LI. Praeger records this little willow-herb from the Counties Down, Antrim and Derry, in the second edition of The Flora of the North-East of Ireland (1938, p. 94). His record for Co. Down reads:?"Colonising the railway-track at Cralgdarragh near

Helen's Bay, 1934: Praeger" and he adds "This little New Zealand plant is appearing, mostly in quite wild ground, even high up on mountains, in many parts of Ireland, and looks like becoming a permanent member of the flora

"

d do not know of any subsequent record for Co. Down, bat no doubt it is now more widely spread than reported by Praeger in 1938. Since that date its name in botanical journals in Britain has twice been changed?firstly to Epilobium pedunculare Cunn. and more recently, in Dandy's List of British Vascular Plants, 1958, to E. nerterioides Cunn,

Since coming to live in Newcastle, Co. Down, some seven years ago I have on several occasions found seedlings of E. nerterioides in my garden, indicating its presence somewhere in the district, but I did not bring it into the garden* nor have I let it seed, to the best of my knowledge. On 11th July, 1963, I discovered it growing on bare damp rock in a disused sandpit in the plantation on N. slope of Drinnahilly, not far above and south-west of Greenhill Park, Newcastle, and on the following day I found it by the side of the newly made road 50 yards east of the new and uppermost bridge over the Glen River, at the top of the famous Donard Falls. This last station is at about 600 feet above sea level, so that its conquest of Slieve Donard and the Mourne range has well begun and it is only a matter of time, I should think, before it colonises suitable damp and bare surfaces throughout

" The Kingdom of Mourne," as It has already

done on the Galtee Mountains in Tipperary, Brandon Mountain in Kerry, and other places.

A NEW STATION FOR SALICORNIA PERENNIS MILL. IN IRELAND

In August, 1963, I found Saliccrnia perennis Mill, growing in a salfcmarsh on the small estuary south-east of Fethard-on-Sea in Co. Wexford. This is the second record for thisj species in Ireland and the locality is about 12 miles west of the saltmarsh near Duncormick Where I discovered S. perennis in 1961 (Irish

Naturalists' Journal XIV, 1962). As far as I know these localities in Co. Wexford have not been visited

by Praeger or other botanists and it seems probable that this species has always been present in Ireland but has been overlooked in the past.

CALLITRICHE HAMULATA KUTZ. IN CORK EAST A Callitriche collected by me in the lake in Glenbower Wood, Killeagh, Co.

Cork, on 28th December, 1962, was identified as Callitriche hamulata Kutz. (C. intermedia). It does not appear to be recorded for vice-county-5. Dr. Franklyn

Perring has kindly confirmed the identification. M. J. P. SCANNELL.

GAUDINIA FRAGILIS (L.) BEAUV. IN IRELAND

In July, 1963, in company with Mr T. Emmet O'Donovan, I botanised some parts of the district between Dunmanus J3ay and Glandore Harbour, West Cork (H.3). At Toormore, West of Schull (where in 1961 Dr Michael Mitchell collected the first Irish record of the pantropfcal lichen Parmelia dilatata Wain.), I found, on the roadside, a pure stand, about 2 feet square, of a grass uniknown to me. On my return to the herbarium and with the aid of Willkomm and Lange,

Prodromus Flora Hispanica I worked the grass out to be Gaudinia fragilis (L.) Beauv. It does not appeared to be recorded for Ireland. The statement in the Spanish flora "in pratis siccis locisque arenosis regionis inferior" describes the habitat at Toormore. I did not notice the plant elsewhere in the area but it may occur.

In Spain the grass !s found in Galicia and other provinces. Dr C. E. Hubbard says that it occurs now and again in Britain as an alien on rubbish tips especially in towns having a connection with countries in south Europe. It is apparently established in a few hay-fields in the Isle of Wight. Elsewhere it occurs in the Mediterranean, North Africa and West Asia. The occurrence of the plant in W. Cork may be due to the activities of Spanish and French fishing trawlers in the area.
