§ Encyclopedia

Erythronium, the fawn lily, trout lily, dog's-tooth-violet or adder's tongue, is a genus of Eurasian and North American plants in the lily family, most closely related to tulips. The name Erythronium derives from Ancient Greek ἐρυθρός (eruthrós) "red" in Greek, referring to the red flowers of E. dens-canis. Of all the established species, most live in North America; only seven species are found in Europe and Asia.
