* Aster amplexifolius. 



Perennial, from a rootstock, ascending at the base, stout, about 4 

 dm. high, viscid-hirsute, especially on the upper portion; basal 

 leaves oblanceolate, about 1.5 dm. long, tapering into a winged pet- 

 iole, entire, rather iirm, in age glabrate above, ciliate on the mar- 

 gins and on the veins beneath ; stem-leaves ovate, clasping ; heads 

 rather few, 12—14 ""'i'^"'- l"iigh? ^"cl nearly 2 cm. in diameter; bracts 

 very unequal, more or less leafy, oblong, acute or the inner Imear- 

 lanceolate, viscid-hirsute; rays numerous, narrow, about 8 mm. long. 



It has been taken for A. integrifolius^ which it resembles m habit, 

 and it may be nearest related to that species, but differs in the 

 foliaceous bracts, the ampler more clasping stem-leaves, and more 

 hirsute stem. It grows on plains.
