18 The Ottawa Naturalist. [April 



collecting season in the Jasper Park region. No complete list 

 of Mr. Spreadbo rough's plants was published, but many new 

 species were described in Pittonia* by Dr. Greene, and notes on 

 interesting species by the writer in The Ottawa Naturalist^ 

 Drummond's plants are all labelled "Rocky Mts. between Lat. 

 52 and Lat. 56," but it is known that he went west from 

 Edmonton to the Rocky Mountains and worked north. All four 

 of the species described by Mr. Standley (Carex atrosquama, 

 Vagnera pumila, Gaillardia bracteosa and Artemisia hrvigata) 

 were collected by Spreadborough and are in the herbarium of 

 the Geological Survey. None of them were thought worthy of 

 specific rank or even of separation from well known species, 

 although Carex atrosquama, now described by MacKenzie, may 

 stand as a segregate from the C. atrata group. Of Vagnera 

 pumila it may be said that none of the characters given by 

 Mr. Standley as separating it from V. trifolia are peculiar to the 

 Jasper Park plant, many of our northern Canadian specimens 

 exhibiting all of them ; the best that can be said of this proposed 

 species is that if separable from V. trifolia of the United States it 

 extends from Newfoundland to the Northern Rockies; among 

 Spreadborough's specimens we find the lcng-exserted raceme and 

 those barely longer than the leaves among plants of the one 

 collecting. An attempt was made by Prof. John Macoun in 

 1884|to separate the forms of G. aristata, but they so intergraded 

 that it was found to be impossible. An examination of some 

 thirty sheets from western Canada shows a wide range of varia- 

 tions and Spreadborough's specimens from Maligne River and 

 from near Henry House give between them all the characters 

 used by Mr. Standley to separate G. bracteosa from G. aristata. 

 Without comparison with a large series of Canadian specimens 

 G. bracteora might stand as a species, but after comparison it 

 must be considered to be only one of the many intergrading 

 forms of G. aristata. Artemisia laevigata may be all right, but it 

 also belongs to a very variable group from which many segregates 

 have been described. It was first collected by Drummond in 

 the Rocky Mountains in Lat. 52. Drummond's plant was 

 referred to ,4. Norvegica by Hooker and to A. arctica by Torrey 

 and Gray. Spreadborough collected it in the Yellowhead Pass. 

 The list of plants, notwithstanding the above criticisms, is a most 

 useful one and the only one available for the Jasper Park region. 

 This special number of the Alpine Club Journal brings 

 together just the kind of information that will be wanted by 

 isitors to Jasper Park and should be in the hands of everyone 

 who goes there. J. M. M.
