Its capitula is 4- 6 in diameter and is globose and quite ovate.
The other species are small herbs with an erect stem, showing tightly clustered or glomerulate groups of capitula.
The main feature of the family is the composite flower type in the form of capitula surrounded by involucral bracts.
The capitula have several overlapping rows of leathery basal simple linear-lanceolate spines.
The male flowers emerge first, followed shortly afterward by the female flowers, which grow into capitula, which are capable of pollination just three days later.
The flowers are borne in paniculate flower heads (capitula).
Under the capitula- tions, these taxes could not be imposed without our consent.
For assisted pollination, male inflorescences were collected and pollen was applied to the stigmas of female flowers by rubbing the male capitula directly against the female flowers.
