We have been enabled to determine this very rare and 

 little-known Aster by comparison with an authentic speci- 

 men out of Michaux's Herbarium, for which we are indebted 

 to M. Achille Richard. Formerly we supposed it to be a 

 new species, and called it A. intricatus ; under which name 

 a few plants have been distributed from the Horticultural 

 Society's Garden, the only collection in which, as far as 

 we are aware, it exists. It was brought thither some 

 years since by Mr. George Don, upon his return from New 

 York ; and was probably found by him in the vicinity of 

 that city. It flowers in October. 



No species can be more distinctly characterised than 

 * So called from the starry appearance of the flowers.
