No, not a Dyckia estevesiiseedling!
This is a Dyckia mirandiana seedling!
One seed out of some fifty germinated.
Dyckia mirandiana was found in Goiás and it is a distichous arranged plant.
I am surprised to see a so young seedling being fan like.
This one is another fan like new Dyckia species species but notice: where are the spines?
We have more to be known about Dyckia than we wonder....
