Galanthus nivalis naturalised "G. nivalis"; others have more specialised collections of many species, forms and cultivars. Galanthus nivalis Galanthus nivalis, the snowdrop or common snowdrop, is the best-known and most widespread of the 20 species in its genus, "Galanthus". Snowdrops are among the first bulbs to bloom in spring and can form impressive carpets of white in areas where they are native or have been naturalised. They should not be confused with the snowflakes, in the genera "Leucojum" and "Acis". The generic name "Galanthus", from the Greek "gala" (milk) and "anthos" (flower), was given to the genus by Carl Linnaeus in 1735.
Chlamydomonas nivalis become one of the most well-studied snow algae. Although its taxonomy is still being settled, the life cycle of this snow algae is now much better understood. The historical disputes about the classification and misclassification of specimens have resulted in a number of names from older publications that all mean to refer to "C. nivalis". These are: "Uredo nivalis", "Sphaerella nivalis", "Protococcus nivalis", and "Haematococcus nivalis". "C. nivalis" has been reported worldwide in mountainous regions, polar regions, or snowfields of every continent. It is the most abundant snow algae and typically composes the majority of cells identified in specimens taken
