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 "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
