The type of the Linnaean genus Conyza is Conyza squarrosa L. 

 but this as well as most of the original species are now included in 

 Inula. Lessing transferred the name Conyza to an entirely different 

 group of plants. Dr. Greene united our North American species 

 with some species of Erigeron into the genus Conyzella Rupr.
