Hybridisation in the wild between closely related species is a common mechanism of speciation in the plant kingdom and, in particular, in the grass family. Here we show the usefulness of integrative taxonomy as a tool for revealing hybridisation events in Stipa (one of the largest genera in Poaceae). We demonstrate the usage of the classical morphological approach combining with scanning electron microscopy data, as well as analyses of pollen grains, and the application of molecular techniques including data derived from next generation sequencing. We illustrate the application of this integrative tool by specific examples: (1) in the S. × heptapotamica hybrid complex comprising morphologically distant but genetically closely related species, and (2) in the S. × lazkovii hybrid complex containing genetically distant species.
