1347 Introduced in 1818. Haller, Allioni, Villars, and 
other botanists, took this for a variety of S. retisa; 
but it appears to be widely different, the leaves being nearly 
three times smaller, and always acute. A very curious little plant, only 
lin. or 2 in. high, of which there are specimens at Henfield, in the Chelsea 
Botanic Garden, and in the arboretum of Messrs. Loddiges.

native of North America, in Labrador. Introduced in 1811, and flowering from April till June. 
Koch observes of this species, that it is very similar to S. Waldsteiniana Willd., and differs only 
in the leaves being strictly entire. The leaves, when young, are sprinkled with villose hairs, but 
soon become glabrous, except at the edge. 
Group xxii. Herbdcee Borrer.
