Native. Uhginal or Paludal. Plentifiil on wet, swampy 

 moors, and over the Highland mountains ; but occuiTing 

 only quite locally as we advance into the southern pro- 

 vinces. It is cmious that so arctic a species should be 

 omitted wholly from the Flora of Shetland. By name, this 

 is the case also with the manuscript Flora of Orkney, now 

 in my possession ; but there can scarcely be a doubt that 

 the " V. odorata, sweet violet. — On wet banks and unculti- 

 vated fields," of Lowe's list, really intends the V. palustris.
