Miscanthus × ogiformis is a hybrid between Miscanthus sacchariflorus and Miscanthus sinensis and its several synonyms indicate the insufficient understanding of the morphological variation of its awn on the spikelet, which is a key characteristic for identifying Miscanthus species. In the present study, all the Miscanthus specimens in 19 herbaria were examined in order to find new localities for Miscanthus × ogiformis . Thirty‐nine Miscanthus × ogiformis specimens appeared to be naturally occurring hybrids, as their callus hair length, awn length, and callus‐to‐spikelet ratio differed from those found in the parental species. Therefore, new Miscanthus ×ogiformis individuals with morphological variations are likely to be discovered and these strains might be useful as new genetic resources for this biomass crop.
