These characteristics bolster the species' reputation as "the classic example" of autopolyploidy
(Baldwin, 1941; Stebbins, 1950; Grant, 1971; Soltis et al., 2007).

Polyploids can originate either from alterations of meiotic or mitotic processes in specimens within a species (autopolyploidy
) or by reproductive contact among species (allopolyploidy) .
Soltis & Soltis included under the name of hybrid speciation two phenomena: the homoploid hybrid speciation (what we have called hybrid, the result of the crossing between two different species resulting in another organism that maintains the same ploidy level as its parentals) and allopolyploidy (even autopolyploidy
when considering that autopolyploidy
may typically involve hybridization between populations of the same species) (Soltis & Soltis 2009).
