Galanthus fosteri" comes from Jordan, Lebanon, Syria, Turkey, and maybe Israel. "Galanthus" grows best in woodland, in acid or alkaline soil, though some are grassland or mountain species. Snowdrops have been known since early times, being described by the classical Greek author Theophrastus in the fourth century BC in his "Περὶ φυτῶν ἱστορία" (Latin: "Historia plantarum", "Enquiry into plants"). He gave it, and similar plants, the name λευκόἲον (λευκος, leukos "white" and ἰόν, ion "violet") from which the later name "Leucojum" was derived. He described the plant as "ἑπεἰ τοῖς γε χρώμασι λευκἂ καἱ οὐ λεπυριώδη" (in colour white and bulbs
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
