This species and 25 are often treated as closely related or even conspecific but are distinguished by the structure of the bulbscales and type of germination. Much further study is required to elucidate their circumscription, relationships and chromosome variation. The chromosome numbers of these taxa are far from clear: different numbers have been reported within and between the two species but the precise identity of the material studied is not always certain.
