Determined according to the botanical keys provided by Werner (1976 in Tutin et al.) to species level and Gajić (1975 in Josifović) to subspecies level.
Species variability: Two subspecies of Cirsium ligulareBoiss. occur in the Osogovo region: Cirsium ligulare subsp. albanum Wettst. and Cirsium ligulare subsp. armatum (Velen.) Petr. Distinction between subspecies:
–Cirsium ligularesubsp. albanumWettst: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 ligularesubsp.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.
Distribution: Native from the Balkan Peninsula according to the distribution information provided by The Euro+Med PlantBase (source: Greuter, 2006+) and the Plants of the World Online portal (Royal Botanic Gardens, Kew).
Habitat: Open habitats – pastures and clearings of forests, from the lowland up to c. 1600 m altitude.
Locality: village of Beli region. Date: 20.09.2020.
