The Arid Biome is a bleak, mostly empty biome like the name would suggest. It is very dry and rocky, with just a couple of dead trees here and there.
What little vegetation spawns in tends to look like a palm tree, or a leafless "dead" tree; no scrub brush will spawn.
This biome has no water at all aside from mini-biomes.
This biome can be find in Dry Grassland planets.
Materials: Dry Sand, Dry Dirt, Cobblestone.
Mini-biomes: Savannah, Desert, Tundra, Ice, Jungle.
