Galanthus earlier authors had mainly relied on was shown to be highly homoplasious. A number of species, such as "G. nivalis" and "G. elwesii" demonstrated intraspecific biogeographical clades, indicating problems with speciation and there may be a need for recircumscription. These clades were assigned names, partly according to Davis' previous groupings. In this model clade Platyphyllus is sister to the rest of the genus. By contrast another study performed at the same time, using both nuclear and chloroplast DNA but limited to the 14 species found in Turkey, largely confirmed Davis' series and subseries, and with biogeographical correlation.

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
