Galanthus woronowii cultivation, it has frequently been confused with two other species, "Galanthus platyphyllus" (usually under its synonym "G. latifolius") and "Galanthus ikariae". All three species have broad green leaves arranged in a supervolute pattern (i.e. wrapped round one another at the base), and inner tepals with a green mark only at the apex. The inner tepals of "G. platyphyllus" lack a sinus at the apex, i.e. they do not have a notched edge. "G. ikariae" and "G. woronowii" are similar, although molecular studies have shown that they are distinct species. Some differences are: Galanthus woronowii Galanthus woronowii, the green snowdrop or
Chlamydomonas nivalis "C. nivalis" is complex, it also helps the algae exploit its niche and survive unfavourable conditions. As a result, "C. nivalis" is one of the best known and studied snow algae. When taking account of the photoprotective effect of its secondary carotenoid, astaxanthin, among the other adaptive mechanisms to its extreme habitat, it can be understood how "C. nivalis" became so dominant in microbial snow algae communities. Green motile offspring are produced in the spring and throughout the summer. They develop into red dormant cysts, the stage where this organism spends most of its life cycle, as the winter season
