 ia my Herbarium, from Mr. Nuttall. In neither is the panicle shorter, but rather longer, than the leaves.

Hab. Northern Canada. Michaux. Woody and barren grounds of North America, from the Saskatchawan 

 to the Arctic Circle. Dr. Bkhardson, and to the Rocky Mountains, in lat. 54^ Drummond. Kotzebue's 

 Sound, in Behring's Strait. Messrs. Lay and Coffie.— This is certainly distinct from the Siberian //. alpmum, 

 being greatly taller, with much shorter stipules, nearly sessile leaves, vastly longer peduncles and rac*;mes, 

 aiid smaller, more deflexed flowers.— The « rugose" appearance noted in the joints of the lomentum of this, 

 by Mr. Nuttall, and of the following, by Dr. Richardspn, appears to be owing to veins or bundles of vessels. 

 Mr. Drummond observes that the bears are very fond of the rooia of this plant.
