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.

Micranthes nivalis Russia, Canada, Alaska and Greenland. The plant was first described by Carl Linnaeus in "Flora Lapponica" (1737), as a result of his Lapland voyage. Some populations from the Canadian Province of Quebec have been recognized as a distinct species by some authors, a variety of "M. nivalis" others: is distinguished from var. "nivalis" by smaller inflorescences and narrower leaves. It is known only from the Shickshock Mountains of the Gaspé Peninsula of southeastern Québec. It has been suggested that this may be a hybrid of "M. nivalis" and "M. tenuis;" further study is warranted. Micranthes nivalis Micranthes nivalis is a
