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 become one of the most well-studied snow algae. Although its taxonomy is still being settled, the life cycle of this snow algae is now much better understood. The historical disputes about the classification and misclassification of specimens have resulted in a number of names from older publications that all mean to refer to "C. nivalis". These are: "Uredo nivalis", "Sphaerella nivalis", "Protococcus nivalis", and "Haematococcus nivalis". "C. nivalis" has been reported worldwide in mountainous regions, polar regions, or snowfields of every continent. It is the most abundant snow algae and typically composes the majority of cells identified in specimens taken
