Subgenus of plants From Wikipedia, the free encyclopedia
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.[1][2] 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.[3]

Padus is the Latin name for the Po River.[4] The term Padus (παδος) in reference to the plant comes from the Greek father of botany, Theophrastus, meaning "from the River Po."[5][6][7]
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.[8] 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:[9][1]
Species formerly included in the genus Maddenia (Chinese: 假稠李, false bird cherries, or 臭樱, odorous cherries) form a monophyletic group. They are similar to bird cherries but lack petals. There are five species:[10][11][12]
Species formerly included in the genus Laurocerasus (cherry laurels) are evergreen and distributed in subtropics and tropics. Examples are:[citation needed]
The Pygeum group is monophyletic if P. africana (possibly as well as P. crassifolia) is excluded. All the species formerly included in the genus Pygeum, except P. africana (and P. crassifolia), are native to tropical Asia and Oceania. They are similar to cherry laurels but lack petals. Examples are:[13]
