I think your right it does look like a Dyckia marnier-lapostollei hybrid. It should pup and will not die after flowering

thank you, turtlew. nice to hear it won´t die!.

This is my 7 month old Dyckia marnier-lapostollei

Nice plant Patusho (^_^)" now you should try to make bigeneric hybrid with your Hechtia.

Hi GArt, it seem your cute Dyck. ml. get a good buddy, Astrophytum cactus isn't it?

I have made many crosses of Dyck. marnier-lapostollei with orther species.

For example this with Dyckia platyphylla.
