A dryad (/ˈdraɪ.æd/; Greek: Δρυάδες, sing.: Δρυάς) is a tree nymph or tree spirit in Greek mythology. Drys signifies "oak" in Greek, and dryads are specifically the nymphs of oak trees, but the term has come to be used for all tree nymphs in general.[1] They were normally considered to be very shy creatures except around the goddess Artemis, who was known to be a friend to most nymphs.

These were nymphs of the laurel trees.

Epimelides
Main article: Epimeliad
The Maliades, Meliades or Epimelides were nymphs of apple and other fruit trees and the protectors of sheep. The Greek word melas—from which their name derives—means both apple and sheep. Hesperides, the guardians of the golden apples were regarded as these type of dryad.

Hamadryad
Main article: Hamadryad
Dryads, like all nymphs, were supernaturally long-lived and tied to their homes, but some were a step beyond most nymphs. These were the hamadryads who were an integral part of their trees, such that if the tree died, the hamadryad associated with it died as well. For these reasons, dryads and the Greek gods punished any mortals who harmed trees without first propitiating the tree-nymphs. (associated with Oak trees)

Meliai
Main article: Meliae
The dryads of ash trees were called the Meliae.[1] The ash-tree sisters tended the infant Zeus in Rhea's Cretan cave. Gaea gave birth to the Meliae after being made fertile by the blood of castrated Uranus. The Epimeliad were nymphs associated with apple trees, and the Caryatids were associated with walnut trees.[1]

Some of the individual dryads or hamadryads are:

Atlanteia and Phoebe, two of the many wives or concubines of Danaus[2]
Chrysopeleia[3]
Dryope[4][5]
Erato[6]
Eurydice
Pitys[7][8]
Tithorea[9]
