Opis (eng)

The genus Galanthus L. (Amaryllidaceae) comprises 22 species, which are perennial bulbous petaloid monocots, commonly known as snowdrops. It is distributed throughout Europe, Asia Minor and the Near East. Galathus spp. are cherished garden plants and the world’s most traded wild-sourced ornamental bulb genus, threatened by illegal collecting and habitat destruction and thus listed in Appendix II of the CITES. However, species delimitation is problematic and the infrageneric classification uncertain, mainly due to the overall morphological similarity within the genus, and lack of easily discernible distinguishing characters. In order to shed light on taxonomy and evolutionary history of Galathus species from the Central Balkans, we analyzed variability of three plastid regions (rps16-trnK, trnLtrnF and trnE-trnT) in 119 individuals from 40 populations representing six species (G. nivalis, G. elwesii and G. reginae-olgae occurring naturally in this region and three allochthonous species, phenology in 21 populations representing two species (G. nivalis and G. elwesii), and variability of 13 quantitative characters in 510 individuals from 17 populations belonging to one species (G. nivalis). Although evolutionary relationships among species were not fully resolved, they were concordant with those based on morphological data (sensu Davis), with the exception of G. gracilis which was not grouped with G. elwesii and G. woronowii. Interspecific hybridization between G. nivalis and G. reginae-olge was detected. We observed a phylogeographic structure in the Balkans, with eight lineages distributed throughout this region. The most recent common ancestor of G. nivalis lineages was dated to the 1.683 Mya (1.089 Mya - 2.376 Mya), and diversification of more or less all G. nivalis lineages took place during the past 0.500 Mya. Phenological differences were observed among six G. nivalis lineages, of which one was characterized also by specific morphological traits.
