Galanthus confused with the other two genera, "Leucojum" and "Acis" (both called snowflakes). "Leucojum" species are much larger and flower in spring (or early summer, depending on the species), with all six tepals in the flower being the same size, though some "poculiform" (goblet- or cup-shaped) "Galanthus" species can have inner segments similar in shape and length to the outer ones. Galantheae are likely to have arisen in the Caucusus. "Galanthus" has about 20 species, but new species continue to be described. "G. trojanus" was identified in Turkey in 2001. "G. panjutinii" (Panjutin's snowdrop) was discovered in 2012 in five locations
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
