Treeborg
From Tardis Wiki, the free Doctor Who reference
"Treeborgs" is the name of the trees in main setting; the forest, in the episode Flesh and Stone. They were partially organic, partially robotic trees kept aboard the Byzantium. The trees were fed and therefore gave out oxygen, which was harvested and sprayed throughout the ship. They were most likely destroyed when the Time Shield activated. (DW: Flesh and Stone)
- Treeborgs is not the official name of the trees but was named that by many fans.
