Terralyn

Humanoid residents of planet Terrellian II. The previously nomadic people colonized the seemingly abandoned planet some three generations prior to Stardate 2314.6. After being attacked by Zar-Tan, it was learned the planets previous occupants, the Thelemites, were still on the planet in the form of plants. After the Thelemites were returned to humanoid form, both peoples agreed to share the planet. (Gold Key Star trek #60 The Empire Man)
