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



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

 mon dandelion, and this is the treatment of the name by Britton 

 (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. 



Apargia 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- 

 r i n i a D. Don, and Thrinica Roth have been at various 

 times commonly used. 



The type of Virea 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 :

 Leontodon Taraxacum L. 



In addition to these, the generic names Asterothrix 

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

 fussia Sch.-Bip., Streckera Sch.-Bip., and Millina 

 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 :
