There have been at least a couple of homebrew versions of Dryads on these boards, however.
Deral'sMorgenstern'sTrue, Deral's has been through an update, though....
Nymph

Attributes: +3 Charisma
Qualities:
-Fey Traits: Natural animals refuse to attack you and often flee from you unless trained to hunt fey, or are attacked by you or your teammates.

Dryad is the same but the first feat has "You may take feats as if you were a Rootwalker and may immediately reduce one of your attributes by 2 to take a Rootwalker subrace," tacked onto the end
