Notobasis

Notobasis (Cass.) Cass.

Notobasis is a monotypic genus from the Mediterranean area and Southwest Asia. It is morphologically and cytologically similar to Cirsium but differs in some respects, e.g. the rounded shape and the abaxial detachment area of the achenes. This somewhat isolated morphological situation is confirmed by ITS sequence data (Häffner & Hellwig 1999).

Its single species, Notobasis syriaca, has rarely been recorded as an alien in Belgium.
