Galanthus L., widely known as snowdrops, is a genus of bulbous monocotyledons, consisting
of 19 distinct species. The genus is confined to Europe, Asia minor and the Near East.
Morphological and molecular characteristics of Galanthus taxa, represented by 12 species (14
taxa) and one hybrid in Turkey, were investigated. Genetic diversity of the Galanthus species
was studied using both nuclear and chloroplast markers. Nuclear ribozomal DNA intragenic
spacer region ITS1, ITS2 and 5.8S rDNA and chloroplast trnL(UAA) intron sequences as
well as the intergenic spacer between trnL(UAA)3’ and trnF(GAA)5’ genes were examined.
Phylogenetic trees were constructed using the sequencing data with 3 phylogenetic methods:
maximum parsimony, neighbour joining and minimum evolution. Phylogenetic trees showed
that species of the same geography clustered together, in contrast to the presently recognized
taxonomy based on morphological chacters. In particular, the taxonomical status of G.
alpinus, G. krasnovii and G. trojanus displayed significant differences compared to
classification table based solely on morphology. This study clearly establishes the
geographical distribution of Galanthus taxa populated within Turkey.
