Taxon discussion

Jacobaea othonnae is rare in Greece, known from the floristic regions of North Pindos (NPi) and NE ( Dimopoulos et al. 2013). In North Pindos, specifically, there is only one record from Mt. Timfi ( Authier 2014), while in the NE, there are records from Mt. Athos ( Boissier 1875, Authier 2014), Mt. Pangeo (a.n. 1983136, LD!) and Mt. Vrondous ( Authier 2014). According to Sutorý (2021), the Mt. Athos plants are somewhat isolated, have woolly-tomentose synflorescences and involucres and belong to the distinct and local subsp. Jacobaea othonnae anomala (Sm.) Sutorý. The rest of the north-eastern populations are attributed to the typical subsp. Jacobaea othonnae othonnae and have glabrous synflorescences and involucres. The plants of Mt. Achladovouno (Fig. 8 ) seem to break this distribution pattern, as they present woolly-tomentose synflorescences, particularly at young age and, therefore, fit subsp. Jacobaea othonnae anomala . Our new collection adds a second mountain locality to subsp. Jacobaea othonnae anomala and extends its distribution ca. 120 km to the north-east (Fig. 7 ).
