Species variability: Two subspecies of Cirsium ligulare Boiss. occur in the Osogovo region: Cirsium ligulare subsp. albanum Wettst. and  Cirsium ligulare subsp. armatum (Velen.) Petr. Distinction between subspecies:

Cirsium ligulare subsp. albanum Wettst: Involucral bracts distinctly widened (lanceolate) below the apical spine; apical spine up to 6 mm long. Widely distributed from the lowland up to 1600 m;

 Cirsium ligulare subsp. armatum (Velen.) Petr.: Involucral bracts gradually narrowed into the apical spine, not distinctly widened in the apical part; the apical spine usually longer as compared to subsp. albanum; found in the higher parts of the Osogovo region;

Lifeform: Biennial; the first year of the lifecycle is vegetative (basal rosette stage). Flowering and fruiting occurs in the second year.
