166 PITTONIA. 
namely at Kicking Horse Lake in 1890, and at Cave Avenue, 
Bauff, in 1891. Easily distinguished from E. Drebachensis, 
to which Mr. Macoun referred it, by its very different habit, 
pubescence and inflorescence; aud the pappus of the latter, 
at least in the American plant, becomes of a rich and beauti- 
ful brown-red in age. The peduncles in the present species, 
though slender, are abruptly and conspicuously enlarged at 
summit under the involucre. 
"EnrGERON PEREGRINUS. Aster peregrinus, Pursh, FI. ii. 596. 
This plant is so exceedingly near the common and widely 
dispersed Erigiron salsuginosus that they are always mixed 
in the herbaria, and sometimes by authors as well. Mr. 
Howell is the only recent collector of the species whose speci- 
mens have gone out to his correspondents correctly named— 
as according to Pursh, Gray and others. In the herbarium 
of the Canadian Survey there are occasionally mounted on 
the same sheet and under the same label this plant and 
E. salsuginosus ; and in the good Alaskan collection made 
by Mr. Funston, and distributed from the U. S. Museum, 
Mr. Coville has wholly mistaken it for that species. It isa 
thoroughly distinct species, recognizable at a glance by the 
eye of the critical; yet, if E. salsuginosus is not to be received 
as an Aster, no more is this. There are, indeed, objections 
to the referring of either species to either Erigeron or Aster ; 
but where one goes the other should. 
Var. Dawsont. Differs from the type in having its leaves 
gradually reduced from the middle of the stem upwards, 
almost as much so as in E. salsuginosus ; and more notably 
different in having twice as many and much more slender 
 involueral bracts, and about 50 rather narrow rays. 
The only specimen seen is in the Canadian Survey collec- 
tion, and was obtained by Mr. Dawson on the Queen Char- 
lotte Islands in 1877. It may easily prove a species, when 
better known.
