Aster nove-angliz L. Sp. Pl. ii, 875 (1753). 
I found specimens with red as well as with blue rays, but do not think this differ- 
ence in color should make it a variety: Thedford, September 7; Halsey, September 
11 (No. 1735). 
Aster oblongifolius Nutt. Gen. ii, 156 (1818). 
Not common: Grant County, near Whitman, September 19 (No. 1780). 
Aster oblongifolius rigidus Gray, Syn. Fl. i, pt ii, 179 (1886). 
More common than the species. On the sand hills and dry prairies: Thedford, 
September 9 (No. 1748). 
Aster multiflorus Ait. Hort. Kew. iii, 203 (1789). 
Dry prairies: Thedford, August 26, September 9 (No, 1731). 
Aster multiflorus stricticaulis Torr. & Gr. Fl. ii, 125 (1841). 
Rare: meadow at Thedford, September 9 (No, 1752). 
Aster multiflorus incano-pilosus (Lindl.) nom. nov; Aster ramulosus incano- 
pilosus Lindl.; Hook. I'l. Bor. Amer. ii, 13 (1834). 
This is 4. commutatus Gray.'! I believe, however, that it should be regarded asa 
variety of A. multiflorus, as it is very hard to draw a line between the two, Mullen, 
September 14 (No. 1765). Specimens with blue rays were collected at Halsey, Sep- 
tember 11 (No. 1754). 
Aster salicifolius Lam. Eneyel. i, 306 (1783). 
This seems to have a little larger head than usual, resembling somewhat 4. long- 
ifolius, ‘The bracts are narrow, thin, acute, but with a broader green tip. Meadows: 
Thedford, September 7; Whitman, September 19 (No. 1739). , 
Aster salicifolius subasper (Lindl.) Gray, Syn. Fl. i, pt. i1, 188 (1884); Aster sub- 
asper Lindl. Hook. Comp. Bot. Mag. i, 97 (1835). 
Lrefer two asters growing commonly along the streams to this species, although 
with some doubt. They both differ from the common form of 4. salicifolius in hav- 
ing larger heads, pubescent stem, and much elongated foliaceous bracts. The latter 
character led me to believe at first that they belonged to A. foliaceus Lindl. Com- 
paring thei with the collection of forms in the National Herbarium I found that 
they are not related to that species. One form has the leaves of the typical A. pan- 
iculatus. This was collected at Thedford, September 7, and near Whitman, Septem- 
ber 18 (No. 1759). The other has shorter, more or less oval, thicker leaves. Plum- 
mer Ford, August 22. 
Aster junceus Ait. Hort. Kew. iii, 204 (1789). 
My plant is like Minnesota specimens in the National Herbarium under this name. 
It seems, however, to have narrower leaves than usual. The bracts have also 
broader, more or less purplish tips. It resembles somewhat a simple, narrow-leafed 
A, tradescanti, but the heads are larger. It also comes near A. ericoides pringlei Gray, 
from which it is distinguished by the broader bracts, In wet meadows, near Thed- 
ford, August 9 (No. 1701). 
The same form was collected by me in the Black Hills of South Dakota in 1892. 
Aster umbellatus pubens Gray, Syn. Fl. i, pt. ii, 197 (1884). 
On the banks of Middle Loup River, Halsey, September 11 (No. 1748). This has 
not been reported for Nebraska before. 
Aster canescens Pursh, Fl. ii, 517 (1814), var. 
A very tall form with many large, subracemose heads and broad, glabrous, dentate 
leaves; otherwise like the next. Plunmer Ford, August 23 (No. 1721). : 
I Syn. Fl. 1, pt. ii, 185 (1884).
