I am not a professional nor an expert in Cactacea or Mammillaria taxonomy. Any help with ID and spelling are always welcome. Photos are for reference only. To up-date my list I've been using many books, journals, catalogs and other web-sites. It's been helpful, but I have more work to do. I only ship to the main 48 States. No international shipping. Please read the front page for ordering information.
