Resumen de Variation in leaf anatomy within the Elytrigia intermedia – E. ×mucronata – E. repens(Poaceae) hybrid complex
Leaf anatomy provides valuable characters for determining plant species. It is unclear, however, how these characters are inherited in hybrids and whether it is possible to determine the parental species of a hybrid using leaf anatomy. The anatomy of leaf blades within the Elytrigia intermedia – E. ×mucronata – E. repens hybrid complex was, therefore, investigated to elucidate its intra- and interspecific variability. A total of twelve characters show considerable differences between the two parental taxa. Their hybrid E. ×mucronata occasionally combines diagnostic traits of both parental species, but some plants have character variants confined to only one parent. This complicates the use of the suggested characters when attempting to distinguish the hybrid from its parents.
