Evigeron canescens T. & G. Fl. N. Am. 2: 179. 1841-2. 
Not Willd. 
This was included in £. caespitosum Nutt. by Dr. Gray, but I 
believe it to be a fairly good species, differing by the more slender 
and erect stems, the longer and narrower leaves, finer pubescence, 
smaller heads and narrower bracts. 
It was collected by Flodman in the Spanish Basin, July 22, 
1896, no. 836. 
ERIGERON ANGUSTIFOLIUS (Gray). 
Aster salsuginosus var. angustifolius Gray, Bot. Calif. 1: 325. 
1876. 
£. salsuginosus var. angustifolius Gray, Proc. Am.Acad. 16: 93. 
1880, 
From the field observations of Mr. Flodmanand myself, I judge 
this to be as good a species as most of the group. It was col- 
lected by Flodman near the Little Belt Pass, Aug. 10, 1896, alti- 
tude 7000 ft., no. 854. 
’ ERIGERON MINOR (Hook). 
£. glabratus var. minor Hook. Fl. Bor. Am. 2: 18. 1834. 
E. armeriaefolus Gray, Proc. Am. Acad. 8: 648. In part. 
1870. Not Turcz. ; 
Gray includes in Z. asmeriacfolius two distinct American plants. 
Neither agrees with the original description. One of these is 
Hooker’s £. glabratus minor, the other his £. lonchophyllus. A 
duplicate of the type of the former is in the Columbia herbarium. 
There are also the following specimens of the same plant: 
Oregon: T. J. Howell, no. 3884. 1884. 
Montana: J. H. Flodman, no. 839, 1896; P. A. Rydberg, no. 
2824. 1895. 
Northwest Territory: John Macoun. 1879. 
South Dakota (Black Hills): P. A. Rydberg, no. 786. 1892. 
Colorado: M. E. Jones, no. 471. 1878. 
All these specimens differ from those cited under the following 
species in the following respects: The stem is low, 1-2 dm. high, — 
very leafy; basal leaves numerous, the lowest spatulate; stem 
leaves linear, without petioles, ciliate at the base; inflorescence ra- 
cemose, with heads on very short pedicels. .
