Selaginella lepidophylla (Selaginellaceae), native to dry forests from Texas and New Mexico to southern Mexico, is known for its ability to survive almost complete desiccation. The branches curl into a tight ball when dry and uncurl into a flat rosette when watered, quickly recovering metabolic activity (common names: ball fern, dinosaur plant, false rose of Jericho, rose of Jericho, resurrection moss, resurrection plant, stone flower).
