Etymology: Nerium is the genus name for the oleander, and the word comes from Greek "nērion," a name used by ancient writers for the same shrub. The Greek form is itself thought to be a borrowing from an older Mediterranean source, though the exact route is uncertain, so it is best to treat that part of the story as unsettled. The name passed into Latin as "nerium" and from there into modern scientific Latin, where Linnaeus and his successors fixed it as the botanical genus. Because the plant grows across the Mediterranean and was widely planted in warm climates, its name spread through botanical and medical writing well before the modern scientific classification took its present shape. The plant's reputation for toxicity runs through the same tradition. Its leaves and sap contain cardiac glycosides, which is why the genus name has long been linked to poisoning warnings in herbals and garden guides.
