The only common species on the mountains was S. commutata^ 

 Bebb., always by rivulets at about 5,000 feet altitude, where snow 

 has lain late in the spring-. S. co?ijuncta, Bebb., was found on 

 one mountain in a similiar habitat. S. nivalis, Hook., which 

 might be expected to be common, was seen only on Tami Hy 

 Mountain at an altitude of 5,500 feet. S. subcordata covered a 

 larg-e boulder at 5,600 feet and S. crassijulis, Trautv , was abun- 

 dant on a rocky slope on Tami Hy Mt. but seen nowhere else. 



Specimens ot all the above were examined by Dr. P. A. 

 Rydberg who has verified my determinations and named the 

 species about which I was uncertain. 



TARAXACUM IN CANADA. 



About a year ago Dr. Edw. L. Greene described several new 

 species of Taraxacum from Canada.* Several sheets of specimens 

 have been added to the Geological Survey collection since our 

 material was examined by Dr. Greene, but these are all referrable 

 to one or other of the species enumerated below. In his intro- 

 ductory note Dr. Greene says : " Indigenous species will probably 

 be found sufficiently numerous though perhaps only upon western 

 mountain territory." It is probably true that the number of in- 

 digenous species in eastern and northeastern Canada is small, 

 perhaps, indeed, there is only one species which ranges from the 

 mountains of eastern Quebec through Labrador and Ungava to 

 Hudson Bay, but that there is at least one indigenous species in 

 eastern Canada no one who has travelled through the unsettled
