Robert Berry was intrigued with this odd seed pod - that of wild cucumber, an annual vine that can be seen growing up several trees at the edge of our ash woodlot. This was a particularly good year for this native vine, growing in places I've not seen it before around the FWG, and in an abundance I haven't seen for a few years. This plant relies on the many seeds it generates for next year's growth. Each plant produces scores of seedpods, and each pod about 8 large flat, disc-like seeds. You can see in this photo, how the bottom of the pod is open to allow the seeds to drop to the ground. They are easy to grow. I sometimes spread a few seeds around my garden in the fall, and bingo!, next year up they come and grow and grow, producing clusters of pretty white flowers. Although they clamber over shrubs and trees, they are a relatively frail vine, and being annual, do no damage.
