Galanthus leaves (vernation). In the era of molecular phylogenetics this characteristic has been shown to be unreliable and now seven moleculary defined clades are recognised corresponding to the biogeographical distribution of species. New species continue to be discovered. Most species flower in winter, before the vernal equinox (20 or 21 March in the Northern Hemisphere), but some flower in early spring and late autumn. Snowdrops are sometimes confused with the two related genera within the tribe Galantheae, snowflakes "Leucojum" and "Acis". All species of "Galanthus" are perennial petaloid herbaceous bulbous (growing from bulbs) monocot plants. The genus is characterised by the
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
