Erigeron canescens T. & G. Fl. N. Am. 2: 179. 1841-2. 

 Not Willd. 



This was included in E. caespitosinn 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).

From the field observations of Mr. Flodman and 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 It., no. 854. 



Erigeron minor (Hook). 



E. glabratus var. minor Hook. Fl. Bor. Am. 2: 18. 1834.

Gray includes in ^. auncriaefoliiisXyNO distinct American plants. 

 Neither agrees with the original description. One of these is 

 Hooker's E. glabratus minor, the other his E. loncJiopJiylliis. 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. 



Nortlnvest Territory : John Macoun. 1879. 



Sot4th 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, i-2 dm. high, 

 very leafy; basal leaves numerous, the lowest spatulate; stem 

 leaves linear, without petioles, ciliateat the base; inflorescence ra- 

 cemose, with heads on very short pedicels.
