Galanthus woronowii Galanthus woronowii Galanthus woronowii, the green snowdrop or Woronow's snowdrop, is a bulbous plant native to north-east Turkey and the west and central Caucasus. In cultivation particularly, it has often been confused with two other species with broad green leaves and a single green mark on the inner tepals: "Galanthus ikariae" and "Galanthus platyphyllus" (usually under its synonym "G. latifolius"). "Galanthus woronowii" grows from a bulb. The leaves are "supervolute", i.e. one leaf is tightly clasped around the other within the bud, usually remaining like this at the base of the plant as it grows. The leaves are generally long,
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
