Prunus subg. Cerasus

'Prunus'' subg. Cerasus' is a subgenus of Prunus.'' Species of the subgenus have a single winter bud per axil. The flowers are usually in small corymbs or umbels of several together (occasionally solitary, e.g. P. serrula), but some species have short racemes (e.g. P. maacki). The fruit is a drupe and has no obvious groove along the side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in North America (P. emarginata and P. pensylvanica), four in Europe (P. avium, P. cerasus, P. fruticosa and P. mahaleb), two in North Africa (P. avium and P. mahaleb), and the remainder in Asia.

The fresh fruits of sweet cherry (worldwide) and Chinese cherry (in China) are consumed raw. The fruits of some species such as sour cherry are used to make desserts, sauce, jam and wine. The seeds of mahaleb cherry are used to make mahleb. Many species are cultivated as an ornamental tree, known as cherry blossoms.

Many Prunus species are called "cherries" but not included in this subgenus. They are not considered true cherries. Examples are:
 * Bush cherries which have three winter buds per axil, such as Oriental bush cherry (P. japonica), humble bush cherry (P. humilis), Nanking cherry (P. tomentosa) and prostrate cherry (P. prostrata), are now included in Prunus subg. Prunus. Sand cherry (P. pumila) also belongs to P. subg. Prunus.
 * Bird cherries (e.g. P. padus, P. grayana, P. napaulensis, P. ssiori), chokecherry (P. virginiana), black cherry (P. serotina), cherry laurels (e.g. P. laurocerasus, P. myrtifolia, P. pleuradenia), holyleaf cherry (P. ilicifolia) and Catalina cherry (P. i. subsp. lyonii) whose flowers and fruits are borne on racemes belong to P. subg. Padus.
 * The phylogenetic position of African cherry (P. africana) is still uncertain, but it is definitely not a true cherry species.
