diaspore
Botanical term for a plant dispersal unit, such as a seed, spore, or fruit, that can be spread to new locations.
Dandelion diaspores are carried far by the wind.
Compound of 散布 (さんぷ, 'scattering, dispersal') and 体 (たい, 'body, unit'). The term is a direct calque of the English botanical term 'diaspore'.
