Native. Viatical, &c. Perhaps fully as frequent as the 

 L. campestre, though usually classed among the rarer spe- 

 cies, by reporters of localities. It is likely that the one is of- 

 ten mistaken for the other of these two species, and that the 

 name of L. campestre' is used, when species ' L. Smithii' 

 is intended. I found it in the bed of the Dee, at Castle- 

 town, the only elevated spot in which I have observed it.
