Serratula tinctoria L.

Flora Europaea the original Linnean specimen perennial, H-G, 2n=22, diploid mesohygrophyle, from the forest-steppe to upper nemoral Palearctic Molinio-Arrhenatheretea R3708-3716 habitats     One of the most characteristic and common species of the mesohygrophyle grasslands. The population from southern Romania seemingly always have individuals with greenish involucral bracts (see the first set of photos below) while the ones from Transylvania have always individuals with blackish-purple involucral bracts (see the second set). Are they different taxa? Also I have to mention that the populations from the south I saw were always placed in forests while the Transylvanian ones always in open damp grasslands and this also might be an explanation. However, a problem worth to be investigated further. Spataru Forest, Buzau county, 12th of August 2006 dr.
