| Genera | |
Prunoideae, also called Amygdaloideae, has been considered a subfamily within the flowering plant family Rosaceae. It was formerly considered by some[2] to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Commercially, important members of the Prunoideae include plum, cherry, apricot, peach, and almond. The fruit of these plants are known as stone fruit (botanically, a drupe), as each fruit contains a hard shell (botanically, the endocarp) called a stone or pit, which contains the single seed.
Taxonomy
The taxonomy of this group of plants within the Rosaceae has recently been unclear. It was reported[3] that Prunoideae consist of two clades, Prunus-Maddenia and Exochorda-Oemleria-Prinsepia. Further refinement[1] shows that Exochorda-Oemleria-Prinsepia is somewhat separate from Prunus-Maddenia-Pygeum, and that, like subfamily Maloideae, all of these genera appear to be best considered within subfamily Spiraeoideae. With this classification the genus Prunus is considered to include Armeniaca, Cerasus, Amygdalus, Padus, Laurocerasus, Pygeum, and Maddenia.
