 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").Within the rose family Rosaceae, it was traditionally placed as a subfamily, the Amygdaloideae (incorrectly "Prunoideae"), but was sometimes placed in its own family, the Prunaceae (or Amygdalaceae).
