It appears to be affected very much in pubescence by 
situation and soil; the garden plant was 11 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 differing 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. ceruleum, 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.
