Galanthus reginae-olgae in particular Greece and former Yugoslavia. It is found in relatively dry, shady woodland. "Galanthus reginae-olgae" is cultivated as an ornamental bulbous plant, particularly the autumn-flowering variants. In cultivation, it requires a warmer and sunnier position than most other "Galanthus" species. The cultivar 'Cambridge', originating from the Cambridge University Botanic Garden, has large green markings on the inner tepals. Galanthus reginae-olgae Galanthus reginae-olgae is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans (parts of Greece and the former Yugoslavia). Some variants produce their pendant white flowers in autumn, others in
Chlamydomonas nivalis "C. nivalis" is complex, it also helps the algae exploit its niche and survive unfavourable conditions. As a result, "C. nivalis" is one of the best known and studied snow algae. When taking account of the photoprotective effect of its secondary carotenoid, astaxanthin, among the other adaptive mechanisms to its extreme habitat, it can be understood how "C. nivalis" became so dominant in microbial snow algae communities. Green motile offspring are produced in the spring and throughout the summer. They develop into red dormant cysts, the stage where this organism spends most of its life cycle, as the winter season
