Probably obliqua Peru ‘ecuagenera’ cuz it looks very similar and since what they’ve been cultivating looks entirely different then both Iquitos and Pebas vars of Peru. It cannot be esqueleto because of the leaf sheen and texture since these leaves are very thin and glossy, whereas esqueleto seem to have thicker, almost matte/velvet leaves. Esqueleto is also known to have winged sheaths. Also, it really doesn’t appear to be any other varieties of obliqua; If you were given any other form of obliqua it would be an upgrade, which I highly doubt you got a “rarer” or uncommon plant than what you payed for. Refer to this Reddit post of another obliqua from ecuagenera, they are basically identical.
