Galanthus (convolute). He merged "Nivalis" and "Plicati" into series "Galanthus", and divided "Latifolii" into two subseries, "Glaucaefolii" and "Viridifolii" . Early molecular phylogenetic studies confirmed the genus was monophyletic and suggested four clades, which were labelled as series, and showed that Davis' subseries were not monophyletic. An expanded study in 2013 demonstrated seven major clades corresponding to biogeographical distribution. This study used nuclear encoded nrITS (Nuclear ribosomal internal transcribed spacer), and plastid encoded "matK" (Maturase K), "trnL-F", "ndhF", and "psbK–psbI", and examined all species recognised at the time, and also two naturally occurring putative hybrids.
