Galanthus nivalis York State, Michigan, Utah, New Jersey, Ohio, Pennsylvania, Maryland, Virginia and North Carolina). Although often thought of as a British native wild flower, or to have been brought to the British Isles by the Romans, it is now thought that it was probably introduced much later, perhaps around the early sixteenth century. "Galanthus nivalis" grows to around 7–15 cm tall, flowering between January and April in the northern temperate zone (January–May in the wild). They are perennial, herbaceous plants which grow from bulbs. Each bulb generally produces two linear, or very narrowly lanceolate, greyish-green leaves and an erect, leafless scape
Chlamydomonas nivalis optimal position in the snow for moisture content, light, and temperature. When in the immotile cyst stage, the "C. nivalis" cells must depend on the flow of meltwater to move it by chance to a favourable area. The temperatures in which this species can survive in ranges from below 0 °C to just above 20 °C. Growth is slow when temperatures are below 5 °C. At 5-15 °C the growth of "C. nivalis" cells can outperform the growth of C. reinhardtii cells. Both species grow at the same rate at 20-25 °C. The growth of "C. nivalis" is suppressed when
