Lime planet
From The Stargate Omnipedia
Desert planet in a distant galaxy, part of a small network of five Stargates. The world may have once been home to marine life. Destiny selected the planet as a site for collecting materials needed to re-supply the ship's spent oxygen purifiers. A dry lake bed was discovered by Matthew Scott some distance from the gate. In it was a sufficient quantity of lime needed to scrub carbon dioxide from the ship's air.
The planet is home to an unusual, desert-dwelling lifeform which displays qualities of sentience.
