Prunus subg. Padus

Prunus subg. Padus is a subgenus of Prunus, characterised by having racemose inflorescences. Padus was originally a distinct genus, but genetic and morphological studies have shown that Padus is polyphyletic.<ref name=":0">Template:Cite journal</ref><ref name=":1">Template:Cite journal</ref> It has been proposed that all the racemose taxa within Prunus (Padus, Maddenia, Laurocerasus and Pygeum) are incorporated into a broad-sense Prunus subg. Padus.<ref>Template:Cite journal</ref>

Padus is the Latin name for the Po River.<ref>Template:Cite web</ref> The term Padus (παδος) in reference to the plant comes from the Greek father of botany, Theophrastus, meaning "from the River Po."<ref>Template:Cite book</ref><ref>Template:Cite book</ref><ref>Template:Cite book</ref>

Species

Padus

Species formerly included in the genus Padus are mostly incorporated into this subgenus, except P. maackii and P. xingshanensis which are included in Prunus subg. Cerasus.<ref>Template:Cite journal</ref> They are deciduous and have small, sour fruit usually only palatable to birds, hence the name bird cherries. Bird cherries are native throughout the temperate Northern Hemisphere, including:<ref>Template:Cite web</ref><ref name=":0" />
