They are born bonded to a certain tree on which their life depends. Some maintain that a Hamadryad is the tree itself, with a normal dryad being simply the indwelling entity, or spirit, of the tree. If the tree should die, the Hamadryad associated with it would die as well. For this reason, both dryads and the other gods would punish mortals (such as King Erysichthon) who harmed trees.

In Greek mythology, the Meliae (also called Meliads) (; or ) were usually considered to be the nymphs of the ash tree, whose name they shared.

In Greek mythology, Chrysopeleia (; ) was a hamadryad nymph.

In Greek mythology, Atlanteia or Atlantia (Ancient Greek: Ἀτλαντείης) was a Hamadryad nymph who consorted with King Danaus of Libya and perhaps the mother of some of the Danaïdes: Hippodamia, Rhodia, Cleopatra, Asteria, Hippodamia, Glauce, Hippomedusa, Gorge, Iphimedusa, and Rhode.
