Most dryads, as
nymphs, were supernaturally long-lived, but the lifespan of
hamadryad nymphs was bound to an individual tree. Hamadryads were inextricably connected with their trees, such that if the tree died, the hamadryad associated with it also died. For these reasons, dryads and the
Greek gods punished any mortal who harmed trees without first
propitiating the tree-nymphs. The dryads of the
ash tree were called the
Meliae. The Meliae sisters tended the infant
Zeus in
Rhea's
Cretan cave. In
Hesiod's
Theogony,
Gaia gave birth to the Meliae after being made fertile by the blood of the castrated
Uranus. Daphnaiai were nymphs of the laurel tree. ==Names==
