Dr. Gamer records this species as growing " in a high pas- 

 ture near Gradbitch." Many years ago, Mr. James Ward 

 favoured me with specimens from the neighbourhood of 

 Richmond, in Yorkshire. It has been long and much 

 grown in gardens as an ornamental plant.

Incognit or Alien. Unless there occurred some mistake 

 between one plant and another in the garden of Mr. Bor- 

 rer, it would seem that a solitary example of the present 

 species had actually been found in a meadow near Hen- 

 field, in Sussex. And it has been picked near Belfast, 

 Ireland. All the other recorded localities probably belong 

 to C. nigrescens or some radiate form of C. nigra. Ac- 

 cording to the Summa Vegetabilium, by Fries, C. Jacea 

 would appear to be generally distributed through Scandi- 

 navia, with the exception of Lapland ; while, on the con- 

 trary, C. nigra is extremely local. This being quite the 

 opposite of their distribution in the British Isles, it may be 

 surmised that there is some misapprehension about the 

 true C. nigra either in Britain or Sweden.
