Dyckia sp from eastern Paraná Mountains

Yes, this is a species and most probably already has a species name.
It looks as a Dyckia brevifolia but brevifolia is a reofitic plant and
this grows up on a mountain

Sometimes or many times it is hard to track back a Dyckia origin
and even doing so it may be very difficult to determine the species.
Remember they to not come tagged.
This baby has some to grow yet and never bloomed here.
