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 "C. nivalis" is complex, it also helps the algae exploit its niche and survive unfavourable conditions. As a result, "C. nivalis" is one of the best known and studied snow algae. When taking account of the photoprotective effect of its secondary carotenoid, astaxanthin, among the other adaptive mechanisms to its extreme habitat, it can be understood how "C. nivalis" became so dominant in microbial snow algae communities. Green motile offspring are produced in the spring and throughout the summer. They develop into red dormant cysts, the stage where this organism spends most of its life cycle, as the winter season
