A plant of the genus Crinum (family Amaryllidaceae), which comprises bulbous perennials of tropical and subtropical areas worldwide, typically having large, showy, lily-like flowers on leafless stems, and which are commonly grown as ornamentals (also more fully "crinum lily"). Also (chiefly in form Crinum): the genus itself.
Mid 18th century; earliest use found in John Hill (bap. 1714, d. 1775), physician and actor. From scientific Latin Crinum, genus name (LinnaeusSpecies plantarum I. 291, after his earlier use in Hortus Cliffortianus 127), alteration of classical Latin crinon, variety of lily (Pliny) from ancient Greek κρίνον lily, a loanword of unknown origin.
