# List of Crocus species

This list of Crocus species shows the accepted species names within the genus Crocus, which are predominantly spring perennial plants in the Iridaceae (iris) family. The list of species is arranged by section. Estimates of the number of species in Crocus have varied widely, from anywhere between 80 and 160, even in the modern era.
Carl Linnaeus originally included two species in 1753, but new species continue to be identified. The deep phylogenetic infrageneric relationships remain unresolved. When subjected to molecular phylogenetic analysis, the sections are well supported but only some of the series. Ongoing, more detailed examination of the various series is leading to a recircumscription, with increasing monophyly. Species segregate to form a basal polytomy of four subclades (A–D). The first clade (A) corresponding to section Crocus, but including C. sieberi and several closely related species (originally included in section Nudiscapus series Reticulati). The remaining three clades (B-D) include all the remaining species of section Nudiscapus. Of these, B and C are small, corresponding to series Orientales and Carpetani respectively, with all remaining series in the large D clade.
