Galanthus reginae-olgae epithet "reginae-olgae" means 'of Queen Olga'; Olga Constantinovna of Russia was then Queen of Greece. The species (or when divided into subspecies, its autonymous subspecies) has been treated as "Galanthus nivalis" subsp. "reginae-olgae". Other regularly used synonyms include "G. olgae" and "G. corcyrensis". The name "Galanthus corcyrensis" has been particularly used for plants that flower in the autumn with the leaves rather than before them. The species has been divided into two subspecies, distinguished by the time of flowering: There is however no sharp division between these two subspecies. "Galanthus reginae-olgae" is native to Sicily and parts of the Balkans,
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
