Galanthus 1805–1815) he divided Liliaceae into a series of "Ordres", and placed Galanthus into the Narcissi "Ordre". This relationship of Galanthus to either liliaceous or amaryllidaceaous taxa (see Taxonomy of Liliaceae) was to last for another two centuries till the two were formally divided at the end of the twentieth century. Lindley (1830) followed this general pattern, placing "Galanthus" and related genera such as "Amaryllis" and "Narcissus" in his Amaryllideae (which he called The Narcissus Tribe in English). By 1853, the number of known plants was increasing considerably and he revised his schema in his last work, placing "Galanthus" together the

They are one of the main algae responsible for causing the phenomenon of watermelon snow, where patches of snow appear red or pink and emit a ripe watermelon odour upon disturbance. The first account of microbial communities that form red snow was made by Aristotle.
