Galanthus other two genera in the modern Galantheae in tribe Amarylleae, order Amaryllidaceae, alliance Narcissales. These three genera have been treated together taxonomically by most authors, on the basis of an inferior ovary. As the number of plants increased, so did the taxonomic complexity. By the time Bentham and Hooker published their "Genera plantarum" (1862–1883) ordo Amaryllideae contained five tribes, and tribe Amarylleae 3 subtribes (see Bentham & Hooker system). They placed "Galanthus" in subtribe Genuinae and included three species. "Galanthus" is one of three closely related genera making up the tribe Galantheae within subfamily Amaryllidoideae (family Amaryllidaceae). Snowdrops are sometimes
Chlamydomonas nivalis begins and remain a cyst until the spring. This alga is an interesting organism for researchers in various fields to study due to its possible role in lowering global albedo, ability to survive in extreme environments, and production of commercially relevant compounds. Additionally, its life cycle is still being studied today in an effort to better understand this organism and amend previous classification errors. The name "Chlamydomonas nivalis" is of Latin origin. It translates to ‘found growing in or near snow’. The Latin meaning describes the organism well as this species of algae are only found associated with snow or
