Obs. This species,— which was first collected here, in 1828, by Dr. Wilmer 

 Worthington and H. H. Van Amringb, Esq.— differs remarkably from all our 

 other Alliums ; and has much resemblance to A. ursinum, of Europe. The large 

 leaves die, and disappear, early in the season— before the flowers are developed. 

 The bulbs emit a fetid disagreeable odor, whilst drying. Three or four additional 

 species are enumerated in the U. States.
