== Subdivision == The genus can be divided into two [[Subgenus|subgenera]]—''Pyrus'' and ''Pashia''. Subgenus ''Pyrus,'' the Occidental [[clade]], is distributed mainly in the western portion of Eurasia and North Africa, while subgenus ''Pashia'', the Oriental clade, is native to [[East Asia]]. The two subgenera come in contact in [[Xinjiang|Xingjiang]], China, and in fact ''[[Pyrus × sinkiangensis|P. sinkiangensis]]'' appears to have arisen from a hybridisation event between ''[[Pyrus communis|P. communis]]'' and either ''[[Pyrus pyrifolia|P. pyrifolia]]'' or ''[[Pyrus × bretschneideri|P. bretschneideri]],'' i.e. a hybridisation between a member of the Occidental clade and a member of the Oriental clade.<ref>{{Cite journal |last1=Jin |first1=Ze-Tao |last2=Ma |first2=Dai-Kun |last3=Liu |first3=Guang-Ning |last4=Hodel |first4=Richard G.J. |last5=Jiang |first5=Yan |last6=Ge |first6=Bin-Jie |last7=Liao |first7=Shuai |last8=Duan |first8=Lei |last9=Ren |first9=Chen |last10=Xu |first10=Chao |last11=Wu |first11=Jun |last12=Liu |first12=Bin-Bin |date=2024 |title=Advancing Pyrus phylogeny: Deep genome skimming-based inference coupled with paralogy analysis yields a robust phylogenetic backbone and an updated infrageneric classification of the pear genus (Maleae, Rosaceae) |url=https://onlinelibrary.wiley.com/doi/abs/10.1002/tax.13163 |journal=Taxon |language=en |volume=73 |issue=3 |pages=784–799 |doi=10.1002/tax.13163 |issn=1996-8175}}</ref> As of December 2024, [[Plants of the World Online]] accepts the following 74 species.<ref>{{Cite web |title=Pyrus L. {{!}} Plants of the World Online {{!}} Kew Science |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:30000967-2#children |access-date=2024-12-27 |website=Plants of the World Online |language=en}}</ref>[[File:Assortment of pears.jpg|thumb|(Left to right, top to bottom) Korean pear, Bosc pear, Forelle pear, red D'Anjou pear, Bartlett pear, green D'Anjou pear, Seckel pear, Comice pear]] [[File:Pyrus pyrifolia.jpg|thumb|Many varieties, such as the [[Nashi pear]], are not "pear-shaped".]] === Species and selected hybrids === {{div col|colwidth=25em}} ;Subgenus ''Pyrus'' * ''[[Pyrus acutiserrata]]'' * ''[[Pyrus armeniacifolia]]''—Apricot-leaved pear * ''[[Pyrus asiae-mediae]]'' * ''[[Pyrus austriaca]]'' * ''[[Pyrus × babadagensis]]'' * ''[[Pyrus × bardoensis]]'' * ''[[Pyrus boissieriana]]'' * ''[[Pyrus bourgaeana]]''—Iberian pear * ''[[Pyrus browiczii]]'' * ''[[Pyrus cajon]]'' * ''[[Pyrus castribonensis]]'' * ''[[Pyrus chosrovica]]'' * ''[[Pyrus ciancioi]]''—Ciancio's pear * ''[[Pyrus communis]]''—European pear ** ''[[Pyrus communis]]'' subsp.
