Galanthus "Akrokorion"), he placed "Galanthus" in the family Liliaceae, section Narcissi. Lamarck provided a description of the genus in his encyclopedia (1786) and later "Illustrations des genres" (1793). In 1789 de Jussieu, who is credited with the modern concept of genera organised in families, placed "Galanthus" and related genera within a division of Monocotyledons, using a modified form of Linnaeus' sexual classification but with the respective topography of stamens to carpels rather than just their numbers. In doing so he restored the name "Galanthus" and retained their placement under Narcissi, this time as a family (known as "Ordo", at that time)
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
