Galanthus elwesii Galanthus elwesii Galanthus elwesii (Elwes's snowdrop, greater snowdrop) is one of a number of species of the genus "Galanthus", herbaceous, perennial, bulbous plants belonging to the family Amaryllidaceae. It is a native of the Caucasus. This herbaceous perennial plant grows to about 20–25 cm high. It grows from a globose bulb, 2–3 cm in diameter. It produces two leaves which are obtuse, linear, and blue-green in colour. The flowers are globose, white, pendulous, and 2–3 cm long, and solitary at the tip of a solid, pointed scape. The outer floral tepals are oblanceolate, with shorter inner tepals that are emarginate
Chlamydomonas nivalis "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
