plus minusve spinuloso-ciliatis, nervis subtus saepe crassis flavidis prominentibus ; folia superiora gradatim 
minora, remote sinuato-pinnatifida vel sinuato-dentata, spinis validioribus nec non crebrioribus armata, 
ceterum ut folia caulina inferiora. 
Capitula in apice caulis et ramorum solitaria vel 2 — 3 approximata, bracteis vel paucis vel 
numerosissimis suffulta, raro ebracteata, magna vel mediocria raro parva, globosa vel ovato-globosa
