Hab, N. W. America. ' Waters of the Koos-koosky. M, Lewis, Common on the springy banks of the 

 Spokan River, near its confluence with the Columbia. Douglas. — This is the most distinct of all the species, 

 remarkable for its cordate, not rhomboidal leaves, and the great length of the petioles. In the structure of 

 the flowers it comes nearest to T. sessile ; but the sepals are nearly as long as the petals, and more erect. 

 Petals dark purple.

 from Kamtschatka, and our Columbia specimens quite agree with them : but I have not seen any Canadian 

 specimens that can exactly be referred to it. At the same time, I am not sure if this be permanently distinct 

 from T, grandijlorum.
