Sphereosis
From Tardis Wiki, the free Doctor Who reference
Sphereosis was a plant whose name meant 'that which feeds from underneath'. It fell very long ago, and there is no information as from where and when. It said it 'started to grow, taking life and nutrients sending out its roots and feelers and tubers', slowly altering its genetic structure until it could walk. It could speak in English but found it difficult, beacuse it was very wheezy and it passed out the Tenth Doctor found it facinating and one of the first things He asked it was it's name. When it replied, it said it did not know. The Doctor asked it what Karl would call it and it said Sphereosis. (AG: The Day of the Troll)
