This list of Narcissus species shows the accepted species names within the genus Narcissus (), which are predominantly spring perennial plants in the amaryllis family Amaryllidaceae. Various common names including daffodil, narcissus, and jonquil are used to describe all or some members of the genus. The list of species is arranged by subgenus and section. Originally in 1753, Carl Linnaeus included only six species, while modern estimates of the number of species in the genus Narcissus have varied widely, from anywhere between 16 to nearly 160 species. , Plants of the World Online accepts 76 species, along with 93 hybrids.
Much of the variation lies in the definition of species, and whether closely related taxa are considered separate species or subspecies. Thus, a very wide view of each species, such as Webb's results in few species, while a very narrow view such as that of Fernandes results in a larger number. Another factor is the status of hybrids, given natural hybridisation. There is a distinction between what are referred to as 'ancient hybrids' which are found occurring over a relatively large area, and 'recent hybrids' with a more restricted range and found growing as solitary plants amongst their parents. The former are more often considered as separate species.
Fernandes (1951) accepted 22 species, on which were based the 27 species listed by Webb in the 1980 Flora Europaea. By 1968, Fernandes had accepted 63 species, and by 1990 Blanchard listed 65 species, and Erhardt 66 in 1993. In 2006 the International Daffodil Register listed 87 species. In contrast, the genetic study by Zonneveld (2008) resulted in only 36 species (for list and comparison with Webb, see Zonneveld Table 4).
Cultivars and species common names can be found in the Royal Horticultural Society's Botanical Classification and list of botanical names which is the basis of their International Daffodil Register. This is a searchable list and had 83 accepted species names in its December 2017 release.
Over 300 synonymous species names are listed, reflecting wide variations in how the genus is divided into species. These have been arranged into Sections. These should not be confused with the horticultural classification of cultivars into divisions by the Royal Horticultural Society
Sections (with type species) shown are according to Zonneveld (2008). In addition Mathew (2002) further divides the sections into subsections.
For a list of species by Section according to the Royal Horticultural Society, see the RHS Botanical Classification (last updated December 2017), which is the basis of their International Daffodil Register.
For the most recent classification, see the list of species from Plants of the World Online placed below the table.
