1660s, species of narcissus, from French jonquille (17c.), from Spanish junquillo, diminutive of junco "rush, reed," from Latin iuncus "reed, rush," from Proto-Italic *joiniko-, from PIE *ioi-ni- (cognates: Middle Irish ain "reeds, rushes," Old Norse einir, Swedish en "juniper"). So called in reference to its leaves. The type of canary bird (1865) is so called for its pale yellow color, which is like that of the flower.
