I receintly acquired a, what I believe I have identified as a mila caespitosa. She is mostly dead. There are a few shoots that are still green at the ends but the rest of the shoot is brown and dry. She has spent the past few months neglected without water or sunlight. I took out the dead and now I have her under a plant light in hopes that she will regenerate. Can anyone tell me, is she a lost cause? What more should I do to make her more comfortable? I don't know much about cacti but I couldn't watch her suffer any longer.

Any help or advice would be greatly appreciated.

Thanks!
