Crupina is a small genus of plants in the tribe Cardueae within the family Asteraceae.
The common crupina Crupina vulgaris is a notorious noxious weed on several continents. The other species, Crupina crupinastrum, also has the potential to become weedy, but it is not as bad a pest at the current time. These are thistle-like plants with bright deep pink flower heads.Flora of China Vol. 20-21 Page 190 半毛菊属 ban mao ju shu Crupina (Persoon) CandolleFlora of North America Crupina (Persoon) de CandolleAltervista Flora Italiana, genere Crupina
