Hi all. I guess I don't know what I am growing - I thought I had P.alata growing from seeds I got from ebay, but I saw passionflow said P.alata leaves are ovate (thanks!!). So, what could this be?

Leaf shape/size looked like P.edulis I used to have, but this plant is darker green and has much darker stem. There are also two nectar glands at the base of each leaf - the leaf end of the petiole.

Any help would be greatly appreciated.
