winged beans

I bought these seeds as "asian winged beans" and planted them in the spring.  They are big happy vines and fruiting as I was told they would when the days grew shorter.  The problem is that yhe beans are decidely not "winged".  Does any one know if these hard flat beans will mature into the asian winged beans or is this something different?

Hii - those look like Lima Beans.
I got some from asian source too - Runners, Perrenial in mild climates
they grow incredibly well !
...but not winged beans

Lima beans would be ok.  Thanks Jen.

Here is a site that offers some uncommon Asian veggies:

It can also be White Flowered Lab-lab bean , Hyacinth bean
...need to see the Flowers opened and the Leaves.

Those are not winged beans, no way.  The 4-edged structure is obvious even when the winged beans are 1 cm long. 

I grew them last year, and was quite happy, despite the long time to harvest.  Didn't have the chance this year.  Looking forward to trying them out in a new location this spring.

My money is on Lablab right now.
because of the amount of seeds visible in some pods...
