Galanthus elwesii in Curtis's Botanical Magazine, and thus the species bears his name as the botanical authority. Later the plants collected by Elwes were found to actually be "G. gracilis" but the name was retained for a different specimen. The species is named in honour of Henry John Elwes. A native of the Caucasus, the species has been widely introduced. "G. elwesii" is grown as an ornamental plant in gardens where they easily naturalise. Bulbs planted in the autumn flower in the early spring. Propagation is by separation of bulbils after flowering. Galanthus elwesii Galanthus elwesii (Elwes's snowdrop, greater snowdrop) is one
Chlamydomonas nivalis such that it is covered by the carotenoid globules full of astaxanthin that will provide protection against UV radiation. The majority (91%) of astaxanthin derivatives are stored in its monoester form within dormant "C. nivalis" red cysts. Astaxanthin is the pigment that makes the cell appear deep red. Other pigments that can also be found in "C. nivalis" include violaxanthin and fadonirubin. Visible algal blooms could be a crucial determinant of surface albedo. It has been suggested that algal blooms partially composed of "C. nivalis" may contribute to lowering ice and snow albedo. The red coloured pigments produced by the
