Galanthus reginae-olgae three smaller inner tepals, white with variable green markings near the tips. The outer tepals are about 15–35 cm long, the inner ones 9–12 mm long. Populations of "Galanthus reginae-olgae" that flower at different times, with or without the leaves being fully developed, have been described as separate species or subspecies. Those described as "G. reginae-olgae" subsp. "reginae-olgae" flower in the autumn, either before the leaves develop or with the leaves. Those described as "G. reginae-olgae" subsp. "vernalis" flower in late winter or early spring, with the leaves. "Galanthus reginae-olgae" was first described in 1876 by Theodoros G. Orphanides. The
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
