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 "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
