Saleucami/Legends

Saleucami is a world that is highly speculated to be in Episode III: Revenge of the Sith. It may be the location shown in the final trailer, overgrown with unusual looking plants with bright yellow bulbs.

Several forums have also talked about the possible planet and what could be located there. It also exists on the Star Wars Clone Wars version of Risk, along with other speculative planets Polis Massa, Mygeeto, and Felusia, and confirmed planets Alderaan, Kashyyyk, Utapau, and Mustafar.
