mondii are hoarily hirsute. Also the figure could not have 

 been made, as a whole, from the last named species, for the 

 rays in Drtimmondii are perhaps twenty times as numerous 

 and almost as narrow as threads. I have a settled opinion 

 that this plate labelled Aster salsuginosiis presents a species not 

 yet named and published, and which awaits rediscovery some- 

 where among the mountains of those great broad provinces 

 of British Columbia or Alberta ; as also the real original 

 salsuginosus of the *' salt plains of the Athabasca'' awaits 

 rediscovery . 



We owe gratitude to Sir William Hooker's memory for his 

 having published that fine daisy that flourished in the Glasgow 

 Garden more than 80 years ago, and shall excuse him for 

 having guessed that the mountaineer beauty of southwestern 

 Canada would be the same as Richardson's of the far northern 

 alkaline plains. Our later synantherologists have all been quite 

 as inconsiderate ; to not one of whom does it seem to have 

 occurred that if the salsuginostis of high northern interior salt 

 plains had ever made its way to Colorado, Wyoming and Utah, 

 men would have found it on the alkaHne or salt plains that 

 are remote from the subalpine sweet-watered meadows and 

 brooksides where alone E. callianthemus is ever seen. In 

 respect to the Pacific coast species, membranaceus , hesperocallis 

 and their kindred, the like is true. Not one of them is of the 

 concourse of those plants which inhabit saline or alkaline low- 

 lands. Every one is of elevated and pure-watered marshes or 

 brooksides, or other moist alluvial grounds. 



Restricted to the Pacific slope, and ranging from British 

 Columbia to southern California, each in its own physiographic 

 region, are several other species of this broad-rayed group 

 which I proceed to name and characterize. 





Erigeron I.ORATUS. Allied to E. callianthemus, but main 

 foliage from basal part of plant extremely narrow, erect, and 

 greatly elongated, 2 to 9 inches long, the lance-linear blades 

 less than V^ inch wide, tapering to an almost equally long |
