FARWELL ON THE FLORA OF DETROIT.

somewhat broadened and slightly hastate hence the name S. hastilc. 

 The construction of the lake mentioned above, I have no doubt, has 

 destroyed the locality. Another species collected by the author near 

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

 believe that several other new species from Michigan have been described 

 as well as a score or more from other districts of the country. Tiola 

 ohliqua Hill and Viola sororia Wild, have been eliminated from 

 V. ciicidata Ait.; V. emarginata (Nutt.) Le Conte and V. ovata Kutt. 

 have been separated from V. saglttata Ait. The common plantain ever- 

 lasting {Antennaria plantaf/inifoUum (Lin.) Richards.) has been divided 

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

 mentioned A. neodioica Greene rar. attenuata Fernald; A. neglecta 

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

 Greene. 



This list does not by 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.
