RYDBERG: Rocky MouUNTAIN FLORA 145 
This species is intermediate between A. oreganus Nutt. and A. 
proximus Greene. It has often been mistaken for the former, as 
it has the same narrow leaves and general habit, but differs in the 
involucre, which is essentially that of A. proximus, consisting of 
foliaceous oblanceolate outer bracts and shorter merely green- 
tipped inner ones ; but the bracts are less squamose and the leaves 
much narrower, darker in color, and firmer.

‘ Aster phyllodes sp. nov. 
Aster foliaceus Britt. & Brown, Ill. Fl. 3: 371 (excluding figure). 
1898. Not A. foliaceus Lindl. 1835. 
The plant described in Britton & Brown’s Illustrated Flora is 
not Aster foliaceus Lindl. of the Northwest, which is a simple 
plant, with 1-3 large heads and narrowly linear-lanceolate leaves. 
The figure in the Illustrated Flora was not drawn from my 
Kimball County plant as stated there. It probably does not rep- 
resent an Astev at all. Evidently some illustrations have been 
interchanged. The Nebraska plant is nearer to A. puniceus in habit 
than to A. foliaceus, although the pubescence and bracts approach 
the latter. It is more closely related to A. proximus Greene, but 
differs in the more or less toothed and more distinctly auriculate, 
darker leaves. 
The only specimens seen are the following :
