I was given a large green spiny pod that's at the moment soft to the touch, it's big enough that when placed in my palm, I can't close my hand around it. I was told that it comes from a climbing plant of some sort. It creeps up into trees & anything it's near. Not sure about the flowers it gets. The pod looks sort of like a chestnut pod only more oblong.
Can anyone tell me what it might be? I'd add a photo but I don't see an option to do that plus my html is turned off in this forum & I'm not sure how to enable it.
