“…Moreover, the border regions of Albania have been considered as “forbidden terra” between 1945-1992. Therefore, it is not surprising that frequently new species have been found there during last 15 years (e.g., Shuka & Jahollari 2007; Shuka 2008, Shuka & Tan 2009; Ranđelović et al 2012; Wagenitz et al 2018; Raca et al 2020).…”

Crocus scardicus and C. pelistericus prefer siliceous soils at elevations between 1700 m and 2450 m. According to Kilias et al (2010) this metamorphic belt developed during the Paleocene to Eocene and stretches between the Korabi-W. Pelagonian zone up to the east of it in the Vardar/Axios ophiolitic belt.…”

Crocus series Scardici has only two members, C. scardicus and C. pelistericus distributed at higher elevations in the Balkan Peninsula. In the course of our research, we discovered two new species growing on alpine meadows and pastures in the serpentine massifs in Albania and limestones in North Macedonia, respectively. The morphology and phylogenetic analyses (two nuclear single-copy markers, nrITS, two chloroplast markers) place the new species within series Scardici. Both new species are closely related to C. scardicus, but morphologically and ecologically clearly differentiated. We also measured genome sizes for all series Scardici species and report here the largest genomes found up to now in crocuses. The impact of different habitat types and isolation on separate mountain ranges in this alpine group of plants is discussed, too.

Centaurea sect. Acrocentron comprises several taxonomically intricate groups of taxa, including the Balkan endemic obligate serpentinophytes: C. melanocephala, C. candelabrum and C. albertii. Despite its distinctive morphological characteristics, C. candelabrum was considered conspecific with C. melanocephala. A similar situation pertains to C. albertii, which has largely been considered a synonym of C. melanocephala. Considering that several recent floristic works treat these taxa as separate species distributed in different serpentinite areas of the Balkans, the main objectives of our study were to analyse the taxonomic and chorological relationships between them, and to propose a new taxonomic concept. Our study was based on an extensive revision of herbarium material, including the type specimens, personal field data and observations of living plants. Our comprehensive study showed that the plants previously recognised as C. melanocephala from the Stolovi mountain in central Serbia and those previously recognised as C. candelabrum from northern Albania deserve the rank of distinct species. These species can be easily distinguished from each other by a number of characters, including their general habitus, the dimensions and shape of the basal leaves, and the indumentum of the involucral bracts. Given the only slight differences observed between the populations in Kosovo and Albania, the question of whether C. albertii is conspecific with C. candelabrum or deserves an independent taxonomic status remains unresolved until further detailed integrative studies are conducted. In view of the clear differences in morphological and ecological characteristics which exist within this group compared to other representatives of sect. Acrocentron, we propose the separation of the studied taxa into a separate C. melanocephala complex, as outlined in this paper.
