I have had some suprises with the seeds I collect from my own Turbinicarpus
Plant on picture one is from a seed produced by a Turbinicarpus dickisoniae but is clearly another thing. Flower reminds me of the T. jauernigii flower. Spines are another thing.
Plant on picture two is from a lophophoroides. Looks like a cross between lophophoroides and knuthianus I would guess.
I didn't expected that Turbinicarpus species could cross like that. Lots of little bees here in the flowering season..
How promiscuous are Turbinicarpus?
Re: How promiscuous are Turbinicarpus?
If you haven't pollinated those intentionally then bees did it. Not many Turbinicarpus spesies pollinate themselves. Yes, they do not look like their mother plants as you said.
If your cacti mess in your job just forget about the job.
