ID quiz of unknown specimen

OK not exactly a quiz, but more of a plea for some help.  About a century ago Mrs. Joseph Clemens collected this specimen in Sonoma Mexico in 1911, and that is all that is certain.  The specimen is in pretty good shape, but it is hard to ID.  The first thought that came to mind was that this was some kind of bladder pod because the fruits look ovoid and were clearly inflated before being pressed.  Note that the specimen has small coiled tendrils, and some smallish flowers.  TPP has not yet taken the more drastic action of removing a flower and rehydrating it for examination.  Thought it might be worth while to try the readers for some recognition first.  Thanks for your help. Leave your suggestions, observations, species names in the comments.
