In section Nudiscapus, series Reticulati was polyphyletic with species intermingled with series Biflori and Speciosi, requiring a recircumscription, confining Reticulati to 8 species, to obtain monophyly. Among the thereby displaced species, are a number of very closely related taxa, referred to as the Crocus sieberi aggregate, which has been proposed as a new series Sieberi. Other new series, such as Isauri and Lyciotauri, continue to be created out of the Biflori series.
