Cactus / retusus v elongatus

This is Ariocarpus retusus v elongatus.
The appearance is very similar to torigonas.
I bought seeds and sowed on 31/08/2006 and grafted young seedlings.
I have 2 plants currently and can collect seeds from these plants.
Recently both of plants were in flower and I crossed them.
I expect to get seeds next late spring.
