Knapweeds are a problematic group ...

... but this does match the description given for Centaurea debauxii in Stace.

Stace describes ...

the "central undivided part of each phyllary" as "lanceolate in shape", as here, but the figure shows a phyllary very similar to C. nigra. C. jacea is shown with a long phyllary, but with the apical region scarcely divided. Photographs of C. jacea on the web include specimens with even less divided phyllaries.

Photographs of C. nigrescens look quite like this, but it is absent from Spain.
