Seedling of Beaucarnea Recurvata?

Hi,

I know how the beaucarnea recurvata looks as adult plant - a palm with leafs like grass. I planted such a palm. But I wonder, if this is the seedling of the Beaucarnea Recurvata? Can anyone help me?

 

Nolina (Beaucarnea) is a monocot so that can't be it.
It would have had a single cotyledon with parallel veins
not two leaves (cotyledons) with branching venation.

 

Thanks. I will keep observing this seedling...

 

Here's a new, recent photo...
