Galanthus have now been lost, and others not seen by the authors). They differ particularly in the size, shape, and markings of the flower, the period of flowering, and other characteristics, mainly of interest to the keen (even fanatical) snowdrop collectors, known as "galanthophiles", who hold meetings where the scarcer cultivars change hands. Double-flowered cultivars and forms, such as the extremely common "Galanthus nivalis" f. "pleniflorus" 'Flore Pleno', may be less attractive to some people, but they can have greater visual impact in a garden setting. Many hybrids have also occurred in cultivation. In the UK these species: and these cultivars:
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
