Caulis A-5-pedalis, versus fastigium fiexuosus, angulatus, pubescens. 

 Folia scepius glabra, nunc levissime pubescentia ; radicalia oblong o-lanceolata, 

 acuminata, in petiolum decurrentia, alte serrata ; proxima ovato-lanceolata ; 

 superiora subsessilia ; suprema Integra. Inflorescentia paniculata, nunc 

 subcorymbosa, magis minusve divisa, semper laxa. Pedunculi uniflori, nunc 

 nudi, nunc subsquamosi. Involucra glabra, foliolis erectis angustis viridibus 

 apice subcoloratis. Flosculi radii pallide lilacini, disci lutei. 



We have not succeeded in determining with what other 

 species this well-marked Aster is confounded by American 

 Botanists. It is neither in Pursh, Michaux, nor Nuttall, 

 as far as we can discover ; and yet it must have been known 

 to some one at least of those writers. The only wild speci- 

 mens we have seen were communicated to us by Dr. Torrey 

 from the western parts of the state of New York. 



It forms a sort of transition from the tall, erect, autumnal 

 species to the dwarfer, cordate-leaved, corymbose kinds,
