rhododendron

Definition

Oleander (Nerium oleander).

Etymology

The obsolete sense derives from Latin rhododendron (“oleander”), from Ancient Greek ῥοδόδενδρον (rhodódendron, “oleander”), from ῥόδον (rhódon, “rose”) + δένδρον (déndron, “tree”). The modern sense comes through the intermediary of the genus name Rhododendron, not closely related taxonomically, but with similar flowers to those of oleander.
