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
Luzula nivalis ellipsoidal, smooth, brown and 1.0–1.2 × 0.6–0.7 mm in size. Basel appendages are fibrillate and up to 0.2 mm long. The fruit of "L. nivalis" is sessile and dry with a persistent and glabrous calyx. The rosette-like whorl of short leaves in "Luzula nivalis" allows it to easily be distinguished from "Luzula confusa". "Luzula nivalis" has been described as having an 'arctic-alpine circumpolar' distribution, as "L. nivalis" is an alpine plant which grows in the arctic regions of the northern hemisphere. Places which "L. nivalis" grows in include Norway, Sweden, Finland and Svalbard. "Luzula nivalis" has been found in a
