There were said in 2008 still to be 60 different named varieties of "Galanthus nivalis" growing at East Lambrook. Several snowdrop varieties discovered in the "ditch garden" at Lambrook since Margery Fish's death have been named and described. Apart from writing eight books
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
