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 have been found on the surface of "C. nivalis" cysts. The unknown bacteria were not detected in control samples that did not contain "C. nivalis" which strongly suggests that it must be associated with the algae. Another bacterium, "Mesorhizobium loti", was found as contamination in a "C. nivalis" culture, but further testing suggested that this bacteria may be synthesizing vitamin B12 for the algae. In cryoconite holes "C. nivalis" can be found among bacteria, virus-like particles, ciliates, and Chlorophyte species. Ice worms have also been found to live preferentially under "C. nivalis" in glaciers, possibly using the algae as a
