Diaspore (botany)
Plant seed or spore and tissues that aid dispersal / From Wikipedia, the free encyclopedia
In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some flowering plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few plants, the diaspore is most or all of the plant, and is known as a tumbleweed.

Diaspores are common in weedy and ruderal species. Collectively, diaspores, seeds, and spores that have been modified for migration are known as disseminules.
