The horn of the lower petal or nectarium is highly re- 

 markable, terminating by a bend upward^s in a short recur- 

 ved rostrum. The leaves have some resemblance to those 

 of Pyrola uniflora and differ from all other Violae by their 

 glandular punctures. In all my specimens, there is but one 

 flower to the stalk, and that considerably elevated above 

 the leaves by a long peduncle. I received ibis interesting 

 species, among a considerable collection of Labrador plants, 

 from my revered friend, R. Rev. C. G. Hueffel now of 

 Bethlehem.
