Fan Dyckias, beautiful sterile Plants

"...like a bridge over troubled waters...I will lay me down..."

Beautiful , unique and sterile plants.
They come from a perfect normal spiral form Dyckia.

The fan arrangement seems to turn its flowers useless for reproduction.
People and Dyckia lovers from around the world argue with the
most weird argumentation for the failing in obtaining viable seeds
from a plant like that.
When people has two plants at bloom they normally accuse the plants of being clones of a same plant. No matter one plant came from Japan and the other from Brazil they will be said to be clone of a very same plant...
All of a sudden all fan Dyckias are clones of the very same plant....all around the globe.
Nonsense!
There is another normal looking plant living with the fan type. The fan Dyckias come from the normal spiral form.
There is no way fan Dyckias to be a species.
How come a true Dyckia species survive without making its owns seeds?
Here instead of saying remember the Alamo we say remember Paradisea apoda...
