Cool seed pods

My Alamo vine (Merremia dissecta) and our surprise Lindheimer's morning-glory (Ipomoea lindheimeri) both put on seed pods this summer. Well, I only got one from the Lindheimer vine. I thought it'd be cool to compare the two pods. Can you guess by looking at the photo above which one is which?
