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.

芒草新产地及芒形态变异

Miscanthus ×ogiformis 是Miscanthus sacchariflorus 和Miscanthus sinensis 的杂交种，它的几个同义词表明对其芒在小穗上的形态变异认识不足，这是识别Miscanthus 物种的关键特征。在本研究中，对 19 个植物标本馆中的所有芒草标本进行了检查，以寻找芒草的新产地。三十九个 Miscanthus ×ogiformis 标本似乎是自然发生的杂种，因为它们的愈伤组织毛发长度、芒长度和愈伤组织与小穗的比率与亲本物种中发现的不同。因此，可能会发现具有形态变异的新芒草个体，这些菌株可能作为这种生物质作物的新遗传资源有用。
