Other claims from this paper (8)
- Observation Agropyron scribneri is endemic to the Rocky Mountains of the Intermountain West, with populations separated by valleys and desert floors.
- Observation A. scribneri is morphologically similar to the A. trachycaulum–Sitanion hystrix hybrid and to the A. trachycaulum x A. scribneri hybrid.
- Mechanism A. scribneri may have originated de novo from hybridization products of A. trachycaulum and S. hystrix.
- Observation Agropyron scribneri appears morphologically similar to its associated S. hysterix population.
- Observation A. trachycaulum x S. hysterix hybrids have some fertility.
- Observation Backcrossing of hybrids onto A. trachucaulum is common.
- Observation Sterile backcross derivatives resembled A. scribneri phenotypically.
- Mechanism The derivatives are interpreted as stabilized hybrid segregants indicating incipient A. scribneri formation.
