Galanthus (convolute). He merged "Nivalis" and "Plicati" into series "Galanthus", and divided "Latifolii" into two subseries, "Glaucaefolii" and "Viridifolii" . Early molecular phylogenetic studies confirmed the genus was monophyletic and suggested four clades, which were labelled as series, and showed that Davis' subseries were not monophyletic. An expanded study in 2013 demonstrated seven major clades corresponding to biogeographical distribution. This study used nuclear encoded nrITS (Nuclear ribosomal internal transcribed spacer), and plastid encoded "matK" (Maturase K), "trnL-F", "ndhF", and "psbK–psbI", and examined all species recognised at the time, and also two naturally occurring putative hybrids. The morphological characteristic of vernation that
Chlamydomonas nivalis the cellular response mechanism to stressful conditions given the harsh conditions of its habitat. It is also an important organism to study adaptation to extreme environments and may become one of the leading systems for research in cold adaptation. "C. nivalis" is likely to have strong antioxidant capabilities, a robust repair mechanism, and other components that may be of interest to researchers. Thermophilic microalgae have gained biotechnological interest as a source for thermostable enzymes and commercial interest as a source for astaxanthin. "C. nivalis" could also potentially be a source for pharmaceuticals, supplements, or beauty products if the algae could
