You know, Elephant ear may sound right. It was a noteworthy tree for sure. It's tricky to recall the details but the tree was huge! And, it produced pods with the most beautiful seeds. There was a hippie van near the beach where I stayed in the Playa Conchal area near Brasilito on the west coast. They created gorgeous necklaces and things with the seeds. We also found wild loofa there!
Yes I do recognize that seed. We do have those here. The seeds are lovely. So pretty.
