- •
Bromus tectorum is a troublesome invasive grass in North America.
- •
The sterility of terminal florets induces a diaspore heteromorphism.
- •
Dispersal of diaspores with and without sterile florets attached was investigated.
- •
Primary and secondary dispersal by biotic and abiotic agents were considered.
- •
Across the study, diaspores with sterile florets were better dispersers.
