FARWELL ON THE FLORA OF DETROIT.

somewhat broadoiuHl and sli^liliy hastate hence the name >^. hastile. 

 Tlie constnicf ion of the lake mentioned above, I liave no doubt, has 

 destroyed tlie locality. Another species colh'cted by the autlior near 

 Birminjiluim has been named by Mr. Bicknell after the discoverer. I 

 believe tliat several otlier new s])ecies from Michij^an have been described 

 as well as a score or more from other districts of the country. T'iola 

 ohliqna Hill and \'i<tl(i sororid Wild, have been eliminated from 

 V. cuculata Ait.; V. cmarginata (Nutt.) Le Conte and V. ovata Nutt. 

 have been separated from V. saf/itiafa Ait. The common ])lantain ever- 

 lasting; {AntcniKiria pJaniafilnifolluin (Lin.) Richards.) has been divided 

 into a score or more species. Amonjj those found at Detroit may be 

 mentioned A. ncodioica Greene var. attenuata Feruald; A. neglecta 

 Greene; A. occidentalis Greene; and A. arnoglossa Greene var. amhigens 

 G reene. 



This list does not b}' any means represent a complete flora of Detroit, 

 but only the results of such work as I have been enabled to do in the 

 field. The sequence of families and nomenclature adopted in this list, 

 except where the application of the rules of priority would require a 

 change, are those exemplified in the Naturlichen Pflanzenfamilien of 

 Engler and Prantl.
