VIREA Adans. Fam. PL, 2: 112. 1763. 



The type of Leontodon L., is L. Taraxacum, the com- 

 mon dandehon, and this is the treatment of the name by Britten 

 (in Britton & Brown, Illus. Fl. Ed. 2, 3: 315. 1913). The 

 numerous other species commonly referred to Leontodon by 

 European writers do not form a wholly homogenous generic 

 group, which is doubtless responsible in large part for the 

 numerous generic names proposed for various species or groups 

 of species more recently comprised in Leontodon. 



A p a r g i a Scop, seems to be the generally accepted name 

 where Leontodon Taraxacum is excluded as being 

 typical of Leontodon, although several other names such 

 as Scorzoneroides Moench, Colobium Roth, Opo- 

 rinia D. Don, and Thrinica p.oth have been at various 

 times commonly used. 



The type of V i r e a Adans. is Leontodon autumn- 

 a 1 e L., and is therefore the earliest generic name for this group 

 of species, none of them native to America, but several of which 

 are well-known naturalized or adventive plants. 



The generic synonyms of Virea Adans. are as follows :

In addition to these, the generic names Asterothrix 

 Cass., Deloderium Cass., Fidelia Sch.-Bip., Kalb- 

 f u s s i a Sch.-Bip., Streckera Sch.-Bip., and M i 1 1 i n a 

 Cass., are referable to V i r e a Adans. 



S. F. Gray divided the species between Thrica (Thrinica) 

 Roth, and Virea Adans., and this general segregation under 

 varying generic names is common to most of the earlier Euro- 

 pean floras, but which if maintained, necessitates the recognition 

 of several other genera, which are more logically regarded as 

 sections of a single genus, the earliest name of which is Virea 

 Adans. 



The species in our flora are as follows :
