Galanthus and referred to the French vernacular name, "" (Snow-pierce), based on the plants tendency to push through early spring snow (see Ecology for illustration)]. The modern family of Amaryllidaceae, in which "Galanthus" is placed, dates to Jaume Saint-Hilaire (1805) who replaced Jussieu's Narcissi with "Amaryllidées". In 1810 Brown proposed that a subgroup of Liliaceae be distinguished on the basis of the position of the ovaries and be referred to as Amaryllideae and in 1813 de Candolle separated them by describing Liliacées and Amaryllidées as two quite separate families. However, in his comprehensive survey of the Flora of France (Flore française,
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
