Quick Summary

Synaptospermy is a plant dispersal strategy where diaspores (seeds and fruits) stick together, making them less mobile. This "sticking together" is a form of atelechory, meaning dispersal over a very limited distance. This strategy is often observed in desert plants and aims to exploit a favorable site more effectively by reducing seed movement. Examples include beets and spinach, where multiple diaspores clump together. Synaptospermy can also be combined with geocarpy, where fruits are produced or buried underground.1
