Etymology: Hamadryas is the Greek word for a wood nymph, literally "dryad sharing the same tree" or "living with the tree" (from "hama," together with, and "drys," oak or tree). In Greek myth, a hamadryad was born with a tree and died when it was cut down, so the name tied the spirit to the living trunk itself. The word moved into zoology because the baboon species Papio hamadryas, the hamadryas baboon, was described by Linnaeus, who borrowed the nymph's name. The reason is the species' home: these baboons live in the dry hills and sparse woodland of the Horn of Africa and the Arabian Peninsula, and ancient writers associated them with that region. The name thus reached English as a scientific label for the monkey rather than as a word about trees. Later, "hamadryas" became a general name for the species group, and the same root gave English the term "hamadryad" for the nymph itself. The monkey's name is therefore a mythological borrowing that outlived its tree.
