crossing echinomatus

[RichR]

Anyone have any experience crossing echinomastus?

I have crossed E. erectocentrus and E. johnsonii, and erectocentrus vars. erectocentrus and acunensis. I got viable seeds from both. I tried to cross E. intertextus and erectocentrus, but nothing came of it.

I'm thinking about crossing intertextus with Warnockii or Mariposensis. It seems like I had them all blooming at the same time last spring
