 Eurybia, in the mythology of the ancients, was the mother of the 

 stars ; and hence the name is poetically applied to a genus of Aster- 

 like plants.

Mab. Low grounds; along Brandywine: frequent. FL May. Fr. Octo. 



Obs. Since my imperfect account of our Hickories was printed, D. Townsenp, 

 Esq. has furnished me with good specimens of undoubted C. amara, collected by 

 himself along the Brandywine. The species is no doubt frequently confounded 

 with C. poreina; and I think they are probably blended by Marshall, under the 

 name oiJuglam alba minima.
