tuation not much above the level of Keswick (which is less 

 than 100 yards above the sea), and as some of the other 

 English habitats have apparently only a trifling elevation, 

 I have considered it to descend within the limits of the 

 midagrarian zone ; although it is more properly a plant of 

 the superagrarian zone. The county of Lancaster requires 

 to be verified by some good modern authority.

Native. Littoral. At the present time this plant is 

 found only on the southern and western coasts; but it has 

 been reported also from the neighbourhood of Yarmouth, 

 in the province of Ouse (Mr. Wigg, 1781) ; from the rocks 

 near Alemouth, in the province of Tyne (Wallis, — sought 

 unsuccessfully by Winch) ; and fi-om the Isles in the Firth 

 of Forth, where it cannot now be found. I suspect that 

 errors occasionally arise, through the English name of this 

 plant, " Samphire," being also applied to Salicornia her- 

 bacea. I have known the most curious mistakes occur, 

 through translations of vernacular names into the wrong 

 botanical names, where there was similarly the choice be- 

 tween two. An Arum has been published under the name 

 of Dioscorea ; Vaccinium Vitis-Idaea, under that of Vac-
