dryad

The term dryad comes from the Greek word for "oak tree". As the Greeks saw it, every tree (not only oaks) had a spirit. The best known of the dryads was Daphne. The beautiful daughter of a river god, she was desired by the god Apollo; as he was about to capture her, she prayed to her father to save her, and he transformed her into a laurel tree. In her honor, Apollo commanded that the poet who won the highest prize every year be crowned with a laurel wreath. The Greeks' respect for trees unfortunately failed to keep Greece's forests from shrinking greatly over the centuries, and those that remain produce little wood of good quality.
