Members of the genus can be deciduous orevergreen. A few species have spiny stems. The leaves are simple, alternate, usuallylanceolate, unlobed, and often with nectarieson the leaf stalk. The flowers are usually white to pink, sometimes red, with five petals and five sepals. There are numerous stamens. Flowers are borne singly, or in umbels of two to six or sometimes more on racemes. The fruit is a fleshy drupe (a "prune") with a single relatively large, hard-coated seed (a "stone").[2]
Within the rose family Rosaceae, it was traditionally placed as a subfamily, theAmygdaloideae (incorrectly "Prunoideae"), but was sometimes placed in its own family, thePrunaceae (or Amygdalaceae). More recently, it has become apparent that Prunus evolved from within a much larger clade now called subfamily Amygdaloideae (incorrectly "Spiraeoideae").[1]
