Wood nymph

A wood nymph (also known as a "dryad") was a creature from Greek mythology that was considered to be the spirit of a tree. They were considered to be shy but beautiful.

While the crew of the USS Enterprise (NCC-1701) was on the planet Gothos, Trelane said to Teresa Ross, "Ah, come, my little wood nymph. Won't you dance with your swain?"
