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 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
