Cherry-laurel

''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. 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''. However, this broad-sense ''Prunus'' subg. ''Padus'' is not monophyletic either.

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''. 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:
*'' Prunus brachypoda'' – China
*''Prunus brunnescens'' – Sichuan and Yunnan
*''Prunus buergeriana'' – Buerger's bird cherry, East Asia and Himalaya
*''Prunus cornuta'' – Himalayan bird cherry, Himalaya
*''Prunus grayana'' – Gray's bird cherry, China and Japan
*''Prunus gyirongensis'' entire-leaved bird cherry, Tibet
*''Prunus napaulensis'' Nepalese bird cherry, China and Himalaya
*''Prunus obtusata'' - China
*''Prunus padus'' – bird cherry or Eurasian bird cherry, Eurasia
*''Prunus perulata'' – Sichuan and Yunnan
*''Prunus serotina'' – black cherry, North America
*''Prunus ssiori'' – Hokkaido bird cherry, Japan and Sakhalin
*''Prunus stellipila'' – China
*''Prunus velutina'' – China
*''Prunus virginiana'' – chokecherry, North America
*''Prunus wilsonii'' – Wilson's bird cherry, China

''Maddenia''

Species formerly included in the genus ''Maddenia'' ( zh, 假稠李, false bird cherries, or , odorous cherries) form a monophyletic group. They are similar to bird cherries but lack petals. There are three species:
* ''Prunus himalayana'' (synonym: ''Prunus gongshanensis'') – Himalayan false bird cherry, southwestern China, Myanmar, Himalaya
* ''Prunus hypoleuca'' (synonyms: ''Prunus fujianensis'', ''Prunus incisoserrata'') – false bird cherry, China
* ''Prunus hypoxantha'' – Sichuan false bird cherry, western to central China

''Laurocerasus''

Species formerly included in the genus ''Laurocerasus'' (cherry laurels) are evergreen and distributed in subtropics and tropics. Examples are:
* ''Prunus amplifolia''
* ''Prunus brittoniana''
* ''Prunus caroliniana''
* ''Prunus ilicifolia''
* '' Prunus integrifolia''
* ''Prunus javanica''
* ''Prunus laurocerasus''
* ''Prunus lusitanica''
* ''Prunus myrtifolia''
* ''Prunus oblonga''
* ''Prunus occidentalis''
* ''Prunus oleifolia''
* ''Prunus phaeosticta''
* ''Prunus reflexa''
* ''Prunus spinulosa''
* ''Prunus tucumanensis''
* ''Prunus undulata''

''Pygeum''

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'', are native to tropical Asia and Oceania. They are similar to cherry laurels but lack petals. Examples are:
* ''Prunus africana''
* ''Prunus arborea''
* ''Prunus costata''
* '' Prunus crassifolia''
* ''Prunus dolichobotrys''
* ''Prunus gazelle-peninsulae''
* ''Prunus grisea''
* ''Prunus lancilimba''
* ''Prunus malayana''
* ''Prunus oligantha''
* ''Prunus oocarpa''
* ''Prunus polystachya''
* ''Prunus pullei''
* ''Prunus schlechteri''
* '' Prunus turneriana''
* ''Prunus wallaceana''
