The flowering heads are much like those of C. giyantea, О. Hotim., except 
for the presence of the distinct though short ligule to the outer florets, 
In addition the leaves of the two are very different, and whereas the 
heads of C. gigantea are closely compacted, those of C. montigena, besides 
being fewer, are much more laxly arranged.
