An Advisor in my office was starting some plants in potting mix. We were surprised to find the plant (see photo; for reference the pots about 4" wide and tall) come up from what assume is the potting mix but could be a seed contaminant. I've looked through a number of references and can't ID it. It is heavily covered with spines like bristly oxtongue but it is not that weed. The spines/bristles are on both sides of the leaves, including the midrib. Also on the stems and petioles. The upper side of the leaves are stippled with dots that are brownish. I am currently growing it until it flowers. That should make it easier to ID.
Any ideas are welcome!
