「Stuffing an anus with seeds at stalk tip」: WISTERIA SEED PODS are dark brown, the color of most freshly defecated feces.
　「Emerging shafts with gonorrhea and buttocks cracks of arrayed spread legs, flattened」WISTERIA SEED PODS burst open in an explosive discharge, not unlike a patient with gonorrhea during clapping treatments to flatten the infected appendage in an effort to expel coagulated blood and gleet:
　「We all know that plants spread their seeds using different mechanisms. Some of the most common methods are distribution by wind, water, and animals. But the most fascinating, at least to me, is explosive dispersal, where a seed pod pops open and flings its seeds away from the plant. …The pea-like pods, unremarkable from an ornamental perspective, are often overlooked in a profusion of vigorous leaf growth, especially because they're green until they mature into 4-6 inch long hard shells. The pods turn brown as they dry on the vine. …[T]he noise is a sharp crack followed by the sound of seeds landing away from the plant. If the wisteria is near a building, you can catch the sound of seeds bouncing off windows or walls, when it's near a driveway or street, you can hear the seeds skitter across the surface. The force of the explosion is truly remarkable. Enough so that I don't look directly at the plant if I'm not wearing glasses. I've seen a seed come to rest a full 70 feet from the plant, starting no more than 8' off the ground and landing in the street (which starts 35' from the plant), coming to rest against the curb on the far side.」
