Though considered a variety of P. Plattensis by Dr. 

 Watson, Prof. Macoun always believed the Rocky Moun- 

 tain plant to be quite distinct from that species, and more 

 nearly related to P. disnecta. Later he came to the con- 

 clusion that it was a good species, and in this opinion he 

 is sustained by Dr. Edw. L. Greene, who has examined 

 the specimens collected on Sheep Mountain in 1895. The 

 above preliminary description is based on his diagnosis. 

 Prof. Macoun has seen the specimens labelled P. Plattensis, 

 var. pinnatisecta in the Grey Herbarium, and believes 

 them to be all referable here. 



Callitricme hamulata, Kiirtz. 



Dr. Morong having examined the specimens referred 

 to this species (Macoun Cat. Can. Plants, Vol. II., p. 322,)
