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 genera Arbutus, Arctostaphylos, Comarostaphylis form a particular type of mycorrhizal symbiosis with the fungus, Arbutoid mycorrhiza , which resembles ectomycorrhizas. [2] [3]

The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants and carnivorous plants.
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.
Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
A mycorrhiza is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry.
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.
The Actinidiaceae are a small family of flowering plants. The family has three genera and about 360 species and is a member of the order Ericales.
Arbutus is a genus of 12 accepted species of flowering plants in the family Ericaceae, native to temperate regions of the Mediterranean, western Europe, the Canary Islands and North America, and commonly called madrones or strawberry trees. The name Arbutus was taken by taxonomists from Latin, where it referred to the species now designated Arbutus unedo.
The Russulaceae are a diverse family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the brittlegills and the milk-caps, well-known mushroom-forming fungi that include some edible species. These gilled mushrooms are characterised by the brittle flesh of their fruitbodies.
An arbuscular mycorrhiza (AM) is a type of mycorrhiza in which the symbiont fungus penetrates the cortical cells of the roots of a vascular plant forming arbuscules. Arbuscular mycorrhiza is a type of endomycorrhiza along with ericoid mycorrhiza and orchid mycorrhiza. They are characterized by the formation of unique tree-like structures, the arbuscules. In addition, globular storage structures called vesicles are often encountered.
Pterospora, commonly known as pinedrops, woodland pinedrops, Albany beechdrops, or giant bird's nest, is a North American genus in the subfamily Monotropoideae of the heath family, and includes only the species Pterospora andromedea. It grows as a mycoheterotroph in coniferous or mixed forests. It is widespread across much of Canada as well as the western and northeastern United States to Mexico. Along with Monotropa it is one of the more frequently encountered genera of the Monotropoideae.
Arbutus unedo, commonly known as strawberry tree, or chorleywood in the United Kingdom, is an evergreen shrub or small tree in the family Ericaceae, native to the Mediterranean Basin and Western Europe. The tree is well known for its fruits, 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.
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.
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.
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.
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.
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.
The subfamily Dialioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees and shrubs. The subfamily consists of 17 genera, which are widespread throughout the tropics. It has the following clade-based definition:
The most inclusive crown clade containing Poeppigia proceraC.Presland Dialium guianense(Aubl.) Sandwith, but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema
Hydroporinae is a subfamily of predaceous diving beetles in the family Dytiscidae. There are at least 2,200 described species in Hydroporinae.
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.
