„ jluitans, Roth., var. rivularis, Lange ? — A species growing 



in abundance in the River Inny, below Ballymahon, 

 has thus been named by Mr. A. Bennett. Unfortu- 

 nately, no ripe fruit was obtained, and this interesting 

 form cannot with certainty be added to the Irish flora 

 until more perfect specimens are gathered. In Symea' 

 English Botany, P. jluitans is referred to as an ex- 

 cluded species, but it has recently been recorded- 

 from one locality in England.
