I have now a concrete example. I have a single Parodia scopa that gave me lots of seeds this year.
According to ADBLPS seed list, this species has self-fertile and self-sterile populations/groups/whatever.
As my plant is solitary, and it produced seeds, I assume it is self-fertile. Or it was pollinated by other Parodia species that were in bloom at the same time.
The important thing is that I harvested lots of seeds that looked normal.
But none germinated.

(My germination method is working fine and I had good germination of all species in the same batch, including other Parodias).

So, what happened? The plant produced non-viable seeds, apparently.

Sounds like my experience with the E.subdenudata - and reinforced after finding this ...

Anyway I'll continue with the C.vuplis-cauda seed. Should it germinate I'll post some pics :)
