Crepis
''Crepis'', commonly known in some parts of the world as hawksbeard or hawk's-beard (but not to be confused with the related genus ''Hieracium'' with a similar common name), is a genus of annual and perennial flowering plants of the family Asteraceae superficially resembling the dandelion, the most conspicuous difference being that ''Crepis'' usually has branching scapes with multiple heads (though solitary heads can occur). The genus name ''Crepis'' derives from the Greek ''krepis'', meaning "slipper" or "sandal", possibly in reference to the shape of the fruit.〔(''Crepis''. ) Flora of North America.〕
The genus is distributed throughout the Northern Hemisphere and Africa,〔Enke, N. and B. Gemeinholzer. (2008). (Babcock revisited: New insights into generic delimitation and character evolution in ''Crepis'' L.(Compositae: Cichorieae) from ITS and matK sequence data. ) ''Taxon'' 57(3) 756-68.〕 and several plants are known as introduced species practically worldwide.〔 The center of diversity is in the Mediterranean.〔
==Ecology==
''Crepis'' species are used as food plants by the larvae of some ''Lepidoptera'' species including the broad-barred white moth. The fly ''Tephritis formosa'' is known to attack the capitula of this plant.
Seeds of ''Crepis'' species are an important food source for some bird species.
