This plant was raised in the Garden of the Horticul- 
tural Society, from seeds collected in the last Arctic Expe- 
dition, and presented to the Society by Dr. Richardson. 
Our motive for figuring it is for the sake of recording 
the differences which exist between it and the common 
P. ceruleum of Europe, but which appear insufficient to 
distinguish it as a species. 
‘ In the first place, its habit is very different: instead 
of an erect stem rising high above the radical leaves, we 
have a plant with a half-recumbent stem, scarcely exceed- 
ing the radical leaves ; instead of a short, dense pubescence 
upon the calyx, we have numerous long loose hairs, which 
are well represented in the plate: but with this peculiarity 
of habit, and slight difference in the calyx, the distinction

cause a feud between two kings, each of whom claimed the merit of its 
discovery, and which finally was named, in commemoration of the struggle, 
wersuanıor, or the War-causing, we know not. Sprengel considers the plant 
of Dioscorides to be the same as the modern Polemonium czeruleum ; but 
if so, this classical war, like many of a more modern date, was for a very 
worthless object.
