Serratula is a genus[3] of plants in the tribe Cardueae within the family Asteraceae native to Eurasia.

[4][5] Plumeless saw-wort is a common name for plants in this genus.

[6] Serratula as traditionally defined contains at least two groups: one of which is basal within the subtribe Centaureinae and one of which is derived; the former group can be moved to the genus Klasea.

[7] Various species contain apigenin, luteolin, quercetin, other flavonoids and ecdysteroids.

[8] Numerous species are now considered members of other genera: This Cardueae article is a stub.
