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 Chlamydomonas nivalis Chlamydomonas nivalis is a unicellular red-coloured photosynthetic green alga that is found in the snowfields of the alps and polar regions all over the world. They are one of the main algae responsible for causing the phenomenon of watermelon snow, where patches of snow appear red or pink and emit a ripe watermelon odour upon disturbance. The first account of microbial communities that form red snow was made by Aristotle. Researchers have been active in studying this organism for over 100 years. Although "C. nivalis" is closely related to "Chlamydomonas reinhardtii", the environmental conditions each species inhabits are
