Genera

The Arbutoideae are a subfamily in the plant family Ericaceae. Phylogenetic analysis supported all genera of the subfamily as monophyletic, except Arbutus . [1] Moreover, it was suggested that the non-sister relationship between Mediterranean and North American species may be explained by a once widespread distribution in the Northern hemisphere before the Neogene. [1]

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulate leaves. The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species.

<span class="mw-page-title-main">Casuarinaceae</span> Family of plants

The Casuarinaceae are a family of dicotyledonous flowering plants placed in the order Fagales, consisting of four genera and 91 species of trees and shrubs native to eastern Africa, Australia, Southeast Asia, Malesia, Papuasia, and the Pacific Islands. At one time, all species were placed in the genus Casuarina. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of Gymnostoma in 1980 and 1982, Allocasuarina in 1982, and Ceuthostoma in 1988, with some additional formal descriptions of new species in each other genus. At the time, it was somewhat controversial. The monophyly of these genera was later supported in a 2003 genetics study of the family. In the Wettstein system, this family was the only one placed in the order Verticillatae. Likewise, in the Engler, Cronquist, and Kubitzki systems, the Casuarinaceae were the only family placed in the order Casuarinales.

<i>Arbutus</i> Genus of flowering plants in the heather family Ericaceae

Arbutus is a genus of 12 accepted species of flowering plants in the family Ericaceae, native to warm temperate regions of the Mediterranean, western Europe, the Canary Islands and North America known as madrones. The name Arbutus was taken from Latin, where it referred to Arbutus unedo.

<i>Arbutus unedo</i> Species of flowering plant in the heather family Ericaceae

Arbutus unedo is an evergreen shrub or small tree in the family Ericaceae, native to the Mediterranean region and western Europe. The tree is well known for its fruit, the arbutus berry, which bear some resemblance to the strawberry — hence the common name "strawberry tree". However, it is not closely related to true strawberries of the genus Fragaria.

<i>Monotropa uniflora</i> Species of flowering plant in the heath family Ericaceae

Monotropa uniflora, also known as ghost plant, ghost pipe, or Indian pipe, is an herbaceous perennial plant native to temperate regions of Asia, North America, and northern South America, but with large gaps between areas. The plant is sometimes completely waxy white, but often has black flecks or pale pink coloration. Rare variants may have a deep red color. The name "Monotropa" is Greek for "one turn" and "uniflora" is Latin for "one flowered" as there is one sharply curved stem for each single flower.

<span class="mw-page-title-main">Detarioideae</span> Subfamily of legumes

The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma and tamarind are two of the most notable species in Detarioideae. It has the following clade-based definition:

The most inclusive crown clade containing Goniorrhachis marginataTaub. and Aphanocalyx cynometroidesOliv., but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema.

<span class="mw-page-title-main">Ericoid mycorrhiza</span> Species of fungus

The ericoid mycorrhiza is a mutualistic relationship formed between members of the plant family Ericaceae and several lineages of mycorrhizal fungi. This symbiosis represents an important adaptation to acidic and nutrient poor soils that species in the Ericaceae typically inhabit, including boreal forests, bogs, and heathlands. Molecular clock estimates suggest that the symbiosis originated approximately 140 million years ago.

<span class="mw-page-title-main">Cercidoideae</span> Subfamily of legumes

Cercidoideae is a subfamily in the pea family, Fabaceae. Well-known members include Cercis (redbuds), including species widely cultivated as ornamental trees in the United States and Europe, Bauhinia, widely cultivated as an ornamental tree in tropical Asia, and Tylosema, a semi-woody genus of Africa. The subfamily occupies a basal position within the Fabaceae and is supported as monophyletic in many molecular phylogenies. At the 6th International Legume Conference, the Legume Phylogeny Working Group proposed elevating the tribe Cercidae to the level of subfamily within the Leguminosae (Fabaceae). The consensus agreed to the change, which was fully implemented in 2017. It has the following clade-based definition:

The most inclusive crown clade containing Cercis canadensisL. and Bauhinia divaricataL. but not Poeppigia proceraC.Presl, Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J.H.Kirkbr. & Wiersema.

<span class="mw-page-title-main">Sophoreae</span> Tribe of legumes

The tribe Sophoreae is one of the subdivisions of the plant family Fabaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. Various morphological and molecular analyses indicated that Sophoreae as traditionally circumscribed was polyphyletic. This led to a re-circumscription of Sophoreae, which resulted in the transfer of many genera to other tribes. This also necessitated the inclusion of two former tribes, Euchresteae and Thermopsideae, in the new definition of Sophoreae. Tribe Sophoreae, as currently circumscribed, consistently forms a monophyletic clade in molecular phylogenetic analyses. The Sophoreae arose 40.8 ± 2.4 million years ago.

<span class="mw-page-title-main">Pyroloideae</span> Subfamily of flowering plants in the heather family Ericaceae

Pyroloideae is a subfamily of plants in the family Ericaceae. It was formerly treated as a separate family, Pyrolaceae. It has also been treated as the tribe Pyroleae within the subfamily Monotropoideae. It consists of four genera: Chimaphila containing 5 species, Pyrola containing 30 species and Moneses and Orthilia which are monotypic. They are mixotrophic, gaining nutrition from photosynthesis, but also from mycorrhizal fungi.

<span class="mw-page-title-main">Monotropoideae</span> Subfamily of flowering plants in the heather family Ericaceae

Monotropoideae, sometimes referred to as monotropes, are a flowering plant subfamily in the family Ericaceae. Members of this subfamily are notable for their mycoheterotrophic and non-photosynthesizing or achlorophyllous characteristics.

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

Epacridoideae is a subfamily of the family Ericaceae. The name StyphelioideaeSweet is also used. The subfamily contains around 35 genera and 545 species. Many species are found in Australasia, others occurring northwards through the Pacific to Southeast Asia, with a small number in South America.
