To be honest, I just know this as a weed who's rhizomes galahs seem to like digging for in autumn and winter.

Oxalis tuberosa. There are four varieties of oxalis that I know of that have tubers, one of which is farmed in NZ (out of something like 750 varieties). I came across many references to new world varieties being eaten. I don't know much about the rest of the world though. There are varieties that have leaves that are poisonous in large quantities.

There are three avenues that a location like the Pyramid could have got hold of edible Oxalis, decorative varieties, weeds and through live tubers sold as a variety of yams.

[Edit] some 40 varieties of oxalis tuberosa exist. NZ yields of commercial grade tubers are up to 18 tonnes per hectare.
