Abstract
The new hybrid X Agrositanion pinalenoensis (Gramineae: Tribe Triticeae) is found in disturbed, forested areas of higher elevations in southern Arizona. In the Pinaleno Mountains where logging has been heavy, numerous disturbed habitats have permitted frequent hybrid populations to persist. Intermediate phenotype, chromosome behavior, lack of seed set, and pollen sterility were used to interpret the status of this hybrid derivative. Introgression and/or segregation are not apparent.
