Galanthus woronowii the inner three, usually about long compared to . Since the flower hangs downwards, the apex of the tepals is at the lowest point. The apex of the inner tepals has a "sinus" (i.e. it has a notch in the middle). There is a green mark around the sinus, either U-shaped or split into two parts on either side. The seed capsule is green, more or less spherical with brown seeds about long. "Galanthus woronowii" was first described in 1935 by the Russian botanist Agnia Losina-Losinskaja. The specific epithet commemorates the botanist and plant collector Yury Nikolaevich Voronov. Particularly in
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
