rhododendron: [17] A rhododendron is etymologically a ‘rose-tree’. The term comes from Greek rhodódendron, a compound formed from rhódon ‘rose’ (apparently a relative of English rose) and déndron ‘tree’ (source of English dendrite [18] and dendrochronology [20]). This denoted the ‘oleander’, an application it retained through Latin rhododendron into English. The first record of its use for the plant we now know as the rhododendron dates from the mid 17th century.
