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 
Lnula. Lessing transferred the name Conyza to an entirely different 
Stoup of plants. Dr. Greene united our North American species 
with some species of Erigeron into the genus Conysella Rupr.
