Cardueae
The Cardueae are a tribe of flowering plants in the daisy family (Asteraceae) and the subfamily Carduoideae. Most of them are commonly known as thistles; four of the best known genera are '' Carduus'', '' Cynara'' (containing the widely eaten artichoke), ''Cirsium'', and ''Onopordum''. They are annual, biennial, or perennial herbs. Many species are thorny on leaves, stems, or involucre, and some have laticifers or resin conduits. Almost 80 genera comprising 2500 species are assigned to this tribe, native of temperate regions of Europe and Asia (especially the Mediterranean region and Minor Asia), Australia and tropical Africa; only three genera contain species native to the Americas.Bremer 1994 ''Asteraceae'': Cladistic and Classification ribe ''Carduae'': 112-156/ref> Taxonomy Cardueae is a synonym for Cynareae, but the name Cynareae was published almost a decade earlier, so has precedence.
