Galanthus plicatus Galanthus plicatus Galanthus plicatus is a species of flowering plant in the family Amaryllidaceae, native from Romania, Ukraine and Crimea in eastern Europe to north Turkey and the north-west Caucasus in Asia. "Galanthus plicatus" is a bulbous perennial plant, growing to about 15 cm tall. Its leaves are bluish or greyish green, broader than many other species of "Galanthus", up to 2 cm wide. The leaf edges are folded back away from the upper surface of the leaf, both in bud and after they expand. The nodding white flowers appear in spring and have six white tepals. The outer three
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
