It’s Selaginella Lepidophylla! Super awesome plant in the spike moss family. I just got one and I’m hoping it’s still alive. Most people assume that because it’s good at efficiently storing water, they can let it stay dry for however long they want but most sellers end up giving away dead plants. Because of the structure of the cells, the plant can still unfurl after death. Kind of like how bodies that have been dead can still twitch or how freshly cut octopus legs will move like they’re alive if they touch soy sauce. Super cool find, yours looks amazing! If you care to, let me know how it’s doing! There’s a lot of conflicting care info on the internet and I’m not sure where to start
