This is just an anecdote:
I love a potato salad with Purslane (Verdolaga in Spanish).
In Europe I knew a variant that we call postelein - see here:

It seems to be rare today in my native Holland, and it is considered a 'forgotten' vegetable.
The version I find here mostly in Mexican or other Latino stores, is Verdolaga, or Purslane.
The version I find here has smaller, and thicker leaves and heavier stems.

I posted here before my favorite recipe, with this style of Purslane/Verdolaga:
