I found a large seed back in the 60’s washed up at the high water line of the Rio Grand river in Texas . It was this shape and size. About the size of a child’s palm. It was the color of an old buckeye (dark chestnut brown) Density, weight, and shell of the seed, reminded me of a buckeye but it was huge and flattened. I have ask park rangers and done web searches with no luck. I thought I would give Walter’s viewers a chance at it. The size and shape is accurate but this is just colorful clay

    Laura, totally not like any mango seed that I have seen. I am leaning towards that Entada genus now, too. Not perfect which one might expect if it was growing out of its native territory. Perhaps the “runt” of the pod. It is in my attic I’m sure. Will search when the weather cools off. Thanks!

    It would be amazing if you could locate the mystery seed! My first thought is the Entada genus, but without seeing the seed I can’t go further.
    Another flat seed that has similar shape (sizes are depending on the species & cultivars). Check out mango seeds images from the Google.
    Appreciate your feedback Jake12121212! Wow, 50 years of treasures! American Pickers might be interested:)

    Well, Laura, until now I figured the seed was either native to the southwest or the last seed from some now extinct plant. If many seeds can survive submerged crossing oceans, it would be a short trip into the Rio Grande watershed. After all it made the trip from Texas to Ohio. I had found it just upstream of the Big Bend Nat’l Park.
    I can easily imagine that it came from a pod as on the side of the seed was a small scar, “hilum”?, that beans have. It is very close to that Entada rheedii, aka African dream herb . Perhaps I’ll make a greater effort to find that seed and getting you a picture.(It is buried under some 50 years’ layers of my treasures. Thanks for working on it, Laura!

    This isn’t an ID. Take look at an unidentified large seed/fruit(?) from the image below.

    Hi jake12121212, it’s difficult without the seed (fruit?). There are numerous fruits & seeds with large scale, I’m reluctant to guess. Have you check out the species of drifted seeds? Take a look at some of them from these included links below. Hope fully someone can ID it for you. Best wishes!
