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 food source. Infections of "C. nivalis" cells by chytrids, "Chytridium chlamydococci", filamentous fungi, and "Selenotila nivalis" have also been observed. As winter approaches, the cells will approach the last stage of their life cycle. The orange cells mature into red cysts, the form in which it will remain for the remainder and longest portion of its life cycle. Cells at this stage are most resistant to harsh environmental conditions. Inorganic and organic materials such as bacteria, fungi, and dust particles coat the mucilage layer of the cell wall. The inorganic impurities were found to be rich in silicon, iron, and
