Editing Crocus (section)

==== Speciation ====

Crocus populations have extremely high infra-specific variability with a very diverse spectrum of morphological and phenotypical varieties, while many individual specimens from different species may closely resemble each other. Based on such morphological differences between isolated populations many new species have been named, but without a definition of new species based on molecular and/or karyological information, species can not be confirmed, creating difficulties in determining [[speciation]] and hence the exact number of species.{{sfn|Harpke et al|2016}}{{sfn|Roma-Marzio et al|2018}} The situation is even more complex once [[Hybridisation (biology)|hybridisation]] (combination of taxa) and [[introgression]] (transfer of genetic material) are considered.{{sfn|Harrison|Larson|2014}}{{sfn|Kerndorff et al|2016}}
