3. Lepachys Raf. In his paper published in the Journal de— 3 
Physique in 1819, Rafinesque erected two species of Rudbeckia into 
new genera, under the names of Ratibida and Lepachys. Since 
that time nearly all writers have considered these two species dis- _ 
tinct from Rudbeckia, yet congeneric, and the resulting genus has 
been known as Oéeliscaria Cass. (a later name) or Lepachys Raf. 
It is indeed strange that no one appears to have noticed that, in 
the Journal de Physique, Ratibida is described before Lepachys. 
However, Ratibida has a better claim to priority than mere posi- 
tion, for it was duly published in the preceding year in the Amer7- 
can Monthly Magazine. The synonymy of the entire genus, as 
now understood, is appended here.
