Canada. {ILioker. Fl.) While e.xploring North Mountain, near 

 Annapolis, N.S., a few years since, a couple of specimens of this variety 

 were gathered. Tliey are smaller flowered than the type, but gener-

 The habitat of 1'. cernuum is alluvial flats, while that of the variety is 

 low damp woods, without reference to streams. The species is scented 

 while the variety is scentless, and the flowers of the former are not half
