Growing Asparagus Pea, also Winged bean

The page refers to 'lotus tetragonolobus' as being asparagus pea, but other web sites have indicated it is 'psophocarpus tetragonolobus' which is asparagus pea. Are they the same? If not are they interchangeable? Do they grow in the same conditions? Wikipedia indicates that only the pod of the lotus version is edible and pretty much all of the psophocarpus version is edible. Can you confirmed?

There is confusion between the two. The 'Lotus' variety (aka purpurea) grows in cooler climates and just the pods are edible. Seedsavers suggest it originated in Africa. The 'Psophocarpus' variety is a tropical plant and most of it is edible. Wikipedia suggests it originated in New Guinea.
