Paris quadrifolia
Flowering plant, family Melanthiaceae
Paris quadrifolia, the herb Paris[3] or true lover's knot, is a species of flowering plant in the family Melanthiaceae. It occurs in temperate and cool areas throughout Eurasia, from Spain to Yakutia, and from Iceland to Mongolia.[1] It prefers calcareous soils and lives in damp and shady places, especially old established woods and stream banks.
P. quadrifolia is in decline in Europe due to loss of habitat.[4] In Iceland, for example, it is on the red list.[5]
