This singular variety does not exceed three inches in height: 
and the leaves rarely attain the length of two; the pinnz are 
placed very close; but the corymb of flowers is most lovely, 
bright purple, nearly as large in diameter as the whole plant 
itself is tall, each blossom being three quarters of an inch in 
breadth. It is common to various parts of Europe, the tem- 
perate as well as the northern districts. 1t is found in Swit- 
zerland, about Basle on the Rhine, and on the Jura: in Ger-. 
many and in England, where it does not affect very alpine 
situations. In Asia it reaches as high north as Kamschatka ; 
in Siberia it grows about Lake Baikal; and Pennant states it 
to be a native of Nootka Sound. What Wahlenberg says of 
the Lapland state of this plant may be applied to the present 
individuals, although it does not afford any reason to infer that 
it is of the same diminutive size: ** longe speciosior mihi visa 
est quam in hortis nostris, corollis margine saturatiore cæru- 
leis superbiens."
