This genus, constituting an intermediate group between Chap- 
talia and Leria, differs from the former in the regularity of the 
limb of the florets of the disk, and from the latter in the female 
florets of the circumference forming. a distinct udis, and bei 
arranged generally in a single series. The purpur 
Willdenow, and. the hieracioides : and speciosa of M. K 
clearly referable to the genus, and perhaps I the Chaptalia 
runcinata; but I doubt whether any of the other plants pu 
included in it are really species of this genus.
