RYDBERG: Rocky MounrTAIN FLORA 141 
imbricated in 3 or 4 unequal series and the leaves are distinctly 
dentate and it agrees in every respect with specimens of A. panicu- 
atus. In the writer's judgment it is nothing but the not uncom- 
mon pinkish- or light lilac-flowered form of that species. 
Aster roseolus sp. nov. 
Perennial, with a horizontal rootstock ; stem 3~—5 dm. high, 
often purple-tinged, glabrous, pilose in lines on the branches ; 
leaves linear, glabrous or nearly so, scabrous-ciliolate on the mar- 
gins, 5-10 cm. long, 5-12 mm. wide, inflorescence paniculate but 
the heads usually few; involucres about 5 mm. high, 8-9 mm. 
broad ; bracts glabrous, oblong or oblong-linear, acute, in about 
3 series, often wholly green, with broadly lanceolate tips; rays 
rose-colored, 5-6 mm. long ; achenes hispiéulous-strigose. 
This species is related to Aster longulus and A. Tradescanti, 
but differs in the bright rose-colored rays, the less numerous heads, 
simpler plant, and broader leaves. It grows in meadows at an alti- 
tude of 1500-2000 m. :

Dr. Gray referred this to Aster junceus but it is more closely 
related to A. Jongifolius, having the subequal bracts and the dark 
green leaves of that species, but the bracts are narrower and 
strictly appressed and the leaves are very narrowly linear and as 
far as I know perfectly entire. It is A. /ariflorus of Lindley 
mainly but he included a specimen of Mrs. Percival’s from eastern 
Canada (apparently of A. yunceus), and this very specimen is the 
type of A. laxiflorus borealis T. & G. Otherwise the species would 
have become J. dorealis Prov., as Provancher raised the variety to 
specific rank. He also characterized the eastern plant. The fol- 
lowing specimens belong to A. /ranklinianus -
