following may be specially noticed. Two plants, either new 

 to or rare in the district, have been found in it and clearly 

 identified -.-^Wolffia arrhiza, Riccia fluitans. 



The "WoLffia, having never before been found in Kent, is 

 now for the first time added to the Flora of this county ; and 

 the discovery of this curious member of the order Lemnacese 

 was the more interesting, as it enabled Mr, GuUiver to 

 complete his observations on the distinctive cell-characters 

 ef Wolffia and Lemna, as described and figured by him 

 in Dr. Seemann's Journal of Botany, January, 1869. The 

 Riccia is a pretty muscal Cryptogam, and the Lemna our 

 lowest and smallest Phanerogam ; and both these diminutive 

 plants will be found novel and interesting for cultivation in 

 vases of fresh water.
