It appears to be affected very much in pubescence by 

 situation and soil ; the garden plant was H foot high, with 

 stems as thick as a goose-quill ; Mr. Douglas's specimens 

 are chiefly about half the size, much more slender, covered 

 with far more numerous flowers, and not diflering in degree 

 of pubescence from the garden plant : but we have from 

 his collection a specimen not more than six inches high, 

 the stems and calyxes of which are densely pubescent, or 

 even villous. This last probably connects the species, as 

 represented in the accompanying plate, with Dr. Graham's 

 Pol. Richardsonii ; unless that plant should be really dis- 

 tinct from P. humile, which Dr. Hooker, in publishing it, 

 seems to doubt, and which we think improbable. We are, 

 however, persuaded that the little plant with fine blue 

 flowers, found by Captain Sabine on the east coast of 

 Greenland, was rightly referred by Dr. Hooker in the first 

 instance to Pol. caeruleum, and is not a state of this species, 

 as the latter skilful Botanist subsequently felt inclined to 

 suppose. See Botanical Magazine, t. 2800. 



Our drawing was made in the Garden of the Horticul- 

 tural Society in August last. It should be cultivated in 

 poor, gravelly soil, which is not dry : under such manage- 

 ment it becomes much more beautiful than if grown in 



rich garden soil.
