This looks like a Parmentiera spp., of the Bignoniaceae family. Possibly Parmentiera aculeata? I took the photos last week in coastal Jalisco, Mexico. A guy I work with propagated a number of plants from seed he collected in his village. Any ID suggestions greatly appreciated. Here’s a link to Crescentia alata, the Mexican calabash tree, a Parmentiera relative also native to the region. Here are a few other previous posts on members of the Bignoniaceae family.
