Galanthus this study corresponded to clade nivalis, subseries "Glaucaefolii" with clade Elwesii and subseries "Viridifolii" with clades Woronowii and Alpinus. However, the model did not provide complete resolution. "sensu" Ronsted et al. 2013 "Galanthus" is derived from the Greek γάλα ("gala"), meaning "milk" and ἄνθος ("anthos") meaning "flower", alluding to the colour of the flowers. The epithet "nivalis" is derived from the Latin, meaning "of the snow". The word "Snowdrop" may be derived from the German "Schneetropfen" (Snow-drop), the tear drop shaped pearl earrings popular in the sixteenth and seventeenth centuries. Other, earlier, common names include Candlemas bells, Fair maids of
Chlamydomonas nivalis cell in combination with inorganic material could enhance the darkening over the snow and reduce the surface area of white snow. Due to the absorption of solar energy by the alga, albedo would be reduced and the darker areas on the snow where the blooms form would melt more rapidly. As a result, populations of "C. nivalis" would increase, creating a feedback loop that amplifies melting and reduces sunlight absorbance which contributes to glacier retreat and lowering albedo, as shown experimentally. This is concerning to environmentalists and climate scientists. "C. nivalis" can be used as a model species for studying
