16 TRANSACTIONS OF THE [Sess. LX XII. 
Naas FLexitis, RostkK ET SCHMIDT, AS A BRITISH PLANT. 
By ArrHur Bennett, F.LS. 
“On October the 11th, 1850, at a meeting of the Botanical 
Society of London, Mr. D. Oliver, junr. (now Emeritus Pro- 
fessor Oliver, LL.D., F.R.S.), exhibited specimens of Naias 
flexilis, Rostk. et Schmidt, discovered by him in a pond 
near Roundstone, Connemara, Ireland, in August last.”? 
This was afterwards gathered by Mr. A. G. More and 
others in Lough Cregduff, which was supposed to be 
Mr. Oliver’s station, although the distance did not quite 
agree. 
In September 1877 Mr. A. G. More gathered it in 
Lough Caragh, S. Kerry, in 15 to 20 feet of water, as- 
sociated with Eriocaulon, Isoetes lacustris, Lobelia Rig 
manna, ete.” 
In August 1885 it was found at Killarney, N. Kerry, by 
the Rev. E. F. Linton!. Gathered at Glencar 1899 and 
Killarney by Dr. Scully. 
Gathered as lately as 1896 by Mr. Lloyd Praeger in 
Lough Cregduff. 
In Scotland. “First found in Loch Cluny, Drummond- 
Hay, 1872.” But Col. Drummond-Hay notes,* on speci- 
mens sent by him, “the discovery of this plant by Mr. 
Sturrock of Blairgowrie in the summer of 1865 (a slip for 
1875).” Iam notable to explain this discrepancy. Messrs. 
Robb and Sturrock found it in Loch Cluny (157 feet above 
sea-level) on 13th August 1875, “growing in water about 
5 feet deep, generally along es Callitriche autumnalis, 
L., or a Chara, but sometimes in patches by itself.” 
In Loch Cluny it is associated with Subularia, Elatine 
hexandra, Callitriche hamulata and autumnalis, Lobelia 
Dortmanna, Littorella, Utricularia sp., Potamogeton 
natans, lucens (2), angustifolius (Zizi), perfoliatus, pre- 
longus, crispus, pusillus, obtusifolius, heterophyllus, Spar- 
ganium minimum (2), Nuphar, three species of aquatic
