The Second Doctor, Jamie and Zoe arrive on xeno-botany lab, Earth Station 454, as it is usurped by The Rosemariners of Rosa Damascena.
Tropes
- Bluff the Impostor: At one point, Biggs and Zoe manage to convince the fake Colbert that Zoe is a member of the station crew by acting like he should already know who she is.
- Call-Back: The dangerous jungle life of Kembel ("The Daleks' Master Plan") is mentioned and is relevant to the story.
- Famed In-Story: Biggs is so renowned as a scientist that the Doctor is immediately impressed at the chance to work with him.
- Fantastic Flora
- Hoist by Their Own Petard: Commander Rugosa is immobilised by the Rosedream he intended to use on others.
- I Know You Know I Know: Invoked when Zoe is in the control room with the fake Colbert, as she muses that they're both trying to bluff the other into thinking they know more about the systems than they actually do but only she knows that Colbert is a fake.
- Laser-Guided Karma: The fake Colbert is consumed by the same plant that ate the original.
- Man-Eating Plant: As Colbert finds out, far too late.
