Xax

From Tardis Wiki, the free Doctor Who reference

Xax was a plant found in the High Plenipotentiary of Mundus Canatari's arboretum. After he was overthrown, the arboretum's reprogrammed security robots gently replanted this and other plants in the arboretum. (PROSE: Wannabes [+]Loading...["Wannabes (novel)"])
