Spiraeoideae

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, [1] leading some authors to define a broader subfamily which includes the Spiraeoideae as well as the Maleae (plants such as pears and apples whose fruits are pomes), and the Amygdaloideae (including almonds and plums, whose fruits are drupes). Such an expanded subfamily is to be called Amygdaloideae under the International Code of Nomenclature for algae, fungi, and plants. [2]

The traditional Spiraeoideae are shrubs. Most have simple leaves, but the genera Aruncus and Sorbaria have pinnately compound leaves. Carpels are usually 2–5. Most genera traditionally placed in the Spiraeoideae produce flowers with distinct follicles that, upon seed-set, mature to form fruits that are aggregates of follicles.

A traditional classification [3] places the following genera in the subfamily:

<span class="mw-page-title-main">Rubiaceae</span> Family of flowering plants including coffee, madder and bedstraw

The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, ornamental cultivars, and historically some dye plants.

<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">Amygdaloideae</span> Subfamily of flowering plants

Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. 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.

Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.

<i>Aronia</i> Genus of plants (chokeberries)

Aronia is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is Aronia melanocarpa which emerged from Eastern North America. The lesser known Aronia arbutifolia and the hybrid form of the abovementioned species called Aronia prunifolia were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species Aronia melanocarpa reached Europe where they were first cultivated in Scandinavia and Russia.

<i>Spiraea</i> Genus of plants

Spiraea, sometimes spelled spirea in common names, and commonly known as meadowsweets or steeplebushes, is a genus of about 80 to 100 species of shrubs in the family Rosaceae. They are native to the temperate Northern Hemisphere, with the greatest diversity in eastern Asia.

<i>Photinia</i> Genus of shrubs in the family RosaceaeG

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

Aruncus is a genus of clump-forming herbaceous perennial plants in the family Rosaceae. Botanical opinion of the number of species differs, with from one to four species accepted. They are closely related to the genera Filipendula and Spiraea, and are native to mountainous damp woodland in temperate regions of the Northern Hemisphere.

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.
