Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, [2] and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. [3] To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011. [4]

Contents

As traditionally defined, the Amygdaloideae includes such commercially important crops as plum, cherry, apricot, peach, and almond. The fruit of these plants are known as stone fruit (drupes), as each fruit contains a hard shell (the endocarp) called a stone or pit, which contains the single seed.

The expanded definition of the Amygdaloideae adds to these commercially important crops such as apples and pears that have pome fruit, and also important ornamental plants such as Spiraea and Aruncus that have hard dry fruits.

Taxonomic history

The name Prunoideae is sometimes used, but is incorrect. The 1835 publication of that name by Gilbert Thomas Burnett (Burnett) is invalid because it lacks a description (or diagnosis or reference to an earlier description or diagnosis). Paul Fedorowitsch Horaninow (Horan.) published the name in 1847, but Amygdaloideae, published in 1832 by George Arnott Walker-Arnott, has priority and is therefore the correct name.

The taxonomy of this group of plants within the Rosaceae has recently been unclear. In 2001 it was reported [5] that Amygdaloideae sensu stricto consists of two distinct genetic groups or "clades", Prunus Maddenia and Exochorda Oemleria Prinsepia . Further refinement [3] shows that ExochordaOemleriaPrinsepia is somewhat separate from PrunusMaddeniaPygeum, and that the traditional subfamilies Maloideae and Spiraeoideae must be included in Amygdaloideae if a paraphyletic group is to be avoided. With this classification, the genus Prunus is considered to include Armeniaca, Cerasus, Amygdalus, Padus, Laurocerasus, Pygeum, and Maddenia.

Robert Frost alluded to the merging of Amygdalaceae into Rosaceae in his poem The Rose Family, [6] when he wrote "The rose is a rose and was always a rose / But the theory now goes that the apple's a rose, / and the pear is, and so's the plum, I suppose." In the next line he wrote, "The dear [i.e., "the dear Lord", euphemized] only knows what will next prove a rose." This referred to shifting botanical opinion which had recently [7] reunited Amygdalaceae, Spiraeaceae, and Malaceae into Rosaceae (which matches de Jussieu's 1789 classification). [8]

<span class="mw-page-title-main">Rosales</span> Order of flowering plants

Rosales is an order of flowering plants. It is sister to a clade consisting of Fagales and Cucurbitales. It contains about 7,700 species, distributed into about 260 genera. Rosales comprise nine families, the type family being the rose family, Rosaceae. The largest of these families are Rosaceae (90/2500) and Urticaceae (54/2600). The order Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families.

<span class="mw-page-title-main">Rosaceae</span> Rose family of flowering plants

Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.

<span class="mw-page-title-main">Maloideae</span> Subfamily of flowering plants

The MaloideaeC.Weber was the apple subfamily, a grouping used by some taxonomists within the rose family, Rosaceae. Recent molecular phylogenetic evidence has shown that the traditional Spiraeoideae and Amygdaloideae form part of the same clade as the traditional Maloideae, and the correct name for this group is Amygdaloideae. Earlier circumscriptions of Maloideae are more-or-less equivalent to subtribe Malinae or to tribe Maleae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals.

<span class="mw-page-title-main">Spiraeoideae</span>

The subfamily Spiraeoideae was traditionally a subfamily of flowering plants within the family Rosaceae. The taxonomy of this subfamily has changed several times in the last century as more detailed studies have been carried out. Spiraeoideae as defined before 2007 is paraphyletic, leading some authors to define a broader subfamily which includes the Spiraeoideae as well as the Maleae, and the Amygdaloideae. Such an expanded subfamily is to be called Amygdaloideae under the International Code of Nomenclature for algae, fungi, and plants.

<i>Prunus</i> Genus of trees and shrubs

Prunus is a genus of trees and shrubs in the flowering plant family Rosaceae that includes plums, cherries, peaches, nectarines, apricots, and almonds. The genus has a cosmopolitan distribution, being native to the North American temperate regions, the neotropics of South America, and temperate and tropical regions of Asia and Africa, There are 340 accepted species. Many members of the genus are widely cultivated for their fruit and for decorative purposes. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena. This shell encloses the seed, which is edible in some species, but poisonous in many others. Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.

<i>Sorbus</i> Genus of flowering plants in the rose family Rosaceae

Sorbus is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of Sorbus (s.l.) are commonly known as whitebeam, rowan, mountain-ash and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species. Recent treatments classify Sorbus in a narrower sense to include only the pinnate leaved species of subgenus Sorbus, raising several of the other subgenera to generic rank.

<i>Prunus <span style="font-style:normal;">subg.</span> Padus</i> Subgenus of plants

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 are incorporated into a broad-sense Prunus subg. Padus.

<i>Chamaemespilus</i> Species of flowering plant in the rose family Rosaceae

Chamaemespilus is a genus of shrubs in the family Rosaceae. It is monotypic, being represented by the single species Chamaemespilus alpina, commonly known as false medlar or dwarf whitebeam. It is native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathians and the Balkans, growing at elevations of up to 2500 m.

<i>Holodiscus</i> Genus of flowering plants

Holodiscus is a genus of flowering plants in the family Rosaceae, native to the Americas, from southwestern British Columbia, Canada and the western United States south to Bolivia.

<i>Adenostoma</i> Genus of flowering plants

Adenostoma is a genus of shrubs in the Rose family (Rosaceae) containing only two species, chamise and redshanks. Both are native to the Californias.

<i>Prunus africana</i> Species of tree

Prunus africana, the African cherry, has a wide distribution in Africa, occurring in montane regions of central and southern Africa and on the islands of Bioko, São-Tomé, Grande Comore, and Madagascar. It can be found at 900–3,400 m (3,000–10,000 ft) above sea level. It is a canopy tree 30–40 m in height, and is the tallest member of Prunus. Large-diameter trees have impressive, spreading crowns. It requires a moist climate, 900–3,400 mm (35–130 in) annual rainfall, and is moderately frost-tolerant. P. africana appears to be a light-demanding, secondary-forest species.

<i>Gillenia</i> Genus of plants

Gillenia is a genus of two species of perennial herbs in the family Rosaceae, Gillenia stipulata and Gillenia trifoliata. Common names for plants in this genus include: Bowman's root, Indian-physic, American ipecac. This genus is endemic to dry open woods with acidic soils in eastern North America. Both plants are subshrubs with exposed semi-woody branches and serrated leaves; the larger lower leaves are divided into palmately arranged leaflets. Plants bloom in May, June, or July; blooms are composed of five slender white petals which are loosely arranged and typically appear slightly twisted and limp as if they were wilted. The flowers mature into small capsules. G. stipulata and G. trifoliata are often planted as ornamentals and used in herbal medicine.

<i>Kageneckia</i> Genus of flowering plants

Kageneckia is a genus of flowering plant in family Rosaceae.

<span class="mw-page-title-main">Neillieae</span> Tribe of flowering plants

Neillieae is a tribe of flowering plants in rose family and the Amygdaloideae subfamily. It includes the genera Physocarpus and Neillia.

<span class="mw-page-title-main">Maleae</span> Tribe of flowering plants

The Maleae are the apple tribe in the rose family, Rosaceae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. Older taxonomies separated some of this group as tribe Crataegeae, as the Cydonia group, or some genera were placed in family Quillajaceae.

<span class="mw-page-title-main">Malinae</span> Subtribe of flowering plants

Malinae is the name for the apple subtribe in the rose family, Rosaceae. This name is required by the International Code of Nomenclature for algae, fungi, and plants, which came into force in 2011 for any group at the subtribe rank that includes the genus Malus but not either of the genera Rosa or Amygdalus. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals.

<i>Aphis pomi</i> Species of true bug

Aphis pomi, commonly known as the apple aphid, or the green apple aphid, is a true bug in the family Aphididae. It is found on young growth of apple trees and on other members of the rose family where it feeds by sucking sap. Reproduction is mainly by parthenogenesis, in which unmated females give birth to live young.

<i>Prunus turneriana</i> Species of plant in the family Rosaceae

Prunus turneriana is a species of plant in the rose, apple and peach family Rosaceae, native to New Guinea and Australia. Its common names include almondbark, wild almond, and joonda. The name almondbark refers to the almond-like odour emitted when the bark is cut. A late successional rainforest tree, it reaches 30 m (98 ft). The fruit is eaten by cassowaries, fruit pigeons, Herbert River ringtail possums and musky rat-kangaroos.
