Margins of lakes— very rare, not found recently. Fl. July {Cyb. Sib.). 

 Down — ** In a lake about half a mile along the road going from Castle- 



wellan to Eathf ryland " ; TempUton. Another note in Mr. 



Templeton's hand says, In the second lake on the road from 



Castlewellan to Kathfriland. 

 Antrim — Lough Neagh at Selshan ; Cyb. Sib. 



There is no lake at half a mile on the road from Castlewellan to Kath- 

 friland, but possibly a formerly existing small lake may have been since 

 drained. If Mr. Templeton's second note be the correct one, it indicates 

 Lough Islandreavy, which is two miles from Castlewellan. This lake 

 has been utilised as a reservoir, and there are now very few aquatic 

 plants to be found about its margins. It is, at all events, nearly certain 

 that the plant is now extinct in Antrim and Down. The notes in Flora 

 of Ulster are erroneous.
