Galanthus nivalis These remarks started the so-called Pusztai affair. The common double snowdrop, "Galanthus nivalis" f. "pleniflorus" 'Flore Pleno', had appeared by 1703, when it was illustrated in "The Duchess of Beaufort's Book". It spread (and was spread) rapidly through northern Europe (by vegetative means, as it sets no seed). With 3–5 outer segments and 12–21 inner segments, which are often misshapen, the flowers may be less attractive to the eye of the purist than single-flowered or neater double cultivars, but they are good value in the garden as the bulbs spread rapidly and the large flowers show up well. There are
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
