XL G. Onopix Raf. Perianthus ventricosus imbri- 
catus caliculatus, caliculus parvus squamosus, 
squamis perianthis apice carinatis mucronatis

sus. Flosculis, tubulosis inequalibus quinquefidis, 
laciniis linearibus, interiora magis incisa, stigma 
simplex : pappus pilosus.—Obs. This genus 
which belongs to the family Cynaridia having a 
division of the corolla more deeply cut, differs 
from Cynara and Pternix by the caliculate peri- 
anthe and simple down : some species of Cnicus or 
Cirsium may perhaps be found to belong to it'; 
their habit is similar. The name was an ancient 
one for some species of Carduus . Raf.
