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 such that it is covered by the carotenoid globules full of astaxanthin that will provide protection against UV radiation. The majority (91%) of astaxanthin derivatives are stored in its monoester form within dormant "C. nivalis" red cysts. Astaxanthin is the pigment that makes the cell appear deep red. Other pigments that can also be found in "C. nivalis" include violaxanthin and fadonirubin. Visible algal blooms could be a crucial determinant of surface albedo. It has been suggested that algal blooms partially composed of "C. nivalis" may contribute to lowering ice and snow albedo. The red coloured pigments produced by the
