Khema represented a type of lifeform that was capable of being irrigated. In the year 231 BBY, Ghal Tarpfen, who held the position of Head of Security at the Starlight Beacon space station, quipped that a dispute regarding the proper method for irrigating khema was the underlying cause of a scuffle involving a team of scientists from the Galactic Agricultural Alliance during their visit.
The plant-like khema was referenced within the second part of the short story "Starlight: Hidden Danger." Justina Ireland authored this story, which appeared in the Star Wars Insider magazine's 204th edition, published on August 10, 2021 as a component of the Star Wars: The High Republic: Starlight series of serialized stories.
