Discaria is a genus of 6 species of flowering plants in the family Rhamnaceae, native to temperate regions of the Southern Hemisphere, in Australia, New Zealand and South America.

Contents

They are deciduous thorny shrubs or small trees growing to 2–5 m tall. They are also non-legume nitrogen fixers.

Many of the world's Discaria species qualify as xerophytes in the true sense of the term, and the Australian species are no exception. They frequently occur on porous or well-drained sites and on soils of low fertility. Some species can fix nitrogen from the atmosphere with the help of symbiotic bacteria ( Frankia ) that form nodules in their roots. [1]

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

Ceanothus is a genus of about 50–60 species of nitrogen-fixing shrubs and small trees in the buckthorn family (Rhamnaceae). Common names for members of this genus are buckbrush, California lilac, soap bush, or just ceanothus. "Ceanothus" comes from Ancient Greek: κεάνωθος (keanōthos), which was applied by Theophrastus to an Old World plant believed to be Cirsium arvense.

<i>Trema</i> (plant) Genus of flowering plants belonging to the hop and hemp family

Trema is a genus of about 15 species of evergreen trees closely related to the hackberries (Celtis), occurring in subtropical and tropical regions of southern Asia, northern Australasia, Africa, South and Central America, and parts of North America. They are generally small trees, reaching 10–20 m (33–66 ft) tall.

<i>Dryas</i> (plant) Genus of flowering plants

Dryas is a genus of perennial cushion-forming evergreen dwarf shrubs in the family Rosaceae, native to the arctic and alpine regions of Europe, Asia and North America. The genus is named after the dryads, the tree nymphs of ancient Greek mythology. The classification of Dryas within the Rosaceae has been unclear. The genus was formerly placed in the subfamily Rosoideae, but is now placed in subfamily Dryadoideae.

<i>Iochroma</i> Genus of shrubs

Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae. Species are native from Mexico to south Brazil. They are found in the forests of Mexico and South America. Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries. The cupular (cup-shaped) calyx is inflated in some species. The leaves are alternate, simple, and entire.

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

Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion.

<i>Elaeagnus</i> Genus of flowering plants in the family Elaeagnaceae

Elaeagnus, silverberry or oleaster, is a genus of about 50–70 species of flowering plants in the family Elaeagnaceae.

<i>Eucryphia</i> Genus of flowering trees and shrubs in the family Cunoniaceae

Eucryphia is a small genus of trees and large shrubs native to the south temperate regions of South America and coastal eastern Australia, mainly Tasmania. Sometimes placed in a family of their own, the Eucryphiaceae, more recent classifications place them in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids.

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

Myrica is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales. The genus has a wide distribution, including Africa, Asia, Europe, North America and South America, and missing only from Australia. Some botanists split the genus into two genera on the basis of the catkin and fruit structure, restricting Myrica to a few species, and treating the others in Morella.

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

Coriaria is the sole genus in the family Coriariaceae, which was described by Linnaeus in 1753. It includes 14 species of small trees, shrubs and subshrubs, with a widespread but disjunct distribution across warm temperate regions of the world, occurring as far apart as the Mediterranean region, southern and eastern Asia, New Zealand, the Pacific Ocean islands, and Central and South America.

<i>Heracleum sphondylium</i> Species of flowering plant in the celery family Apiaceae

Heracleum sphondylium, commonly known as hogweed or common hogweed, is a herbaceous perennial plant in the carrot family Apiaceae, which includes fennel, cow parsley, ground elder and giant hogweed. It is native to most of Europe, western Asia and northern Africa, but is introduced in North America and elsewhere. Other common names include cow parsnip or eltrot. The flowers provide a great deal of nectar for pollinators.

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

Purshia is a small genus of 5–8 species of flowering plants in the family Rosaceae which are native to western North America.

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

Colletia is a genus of flowering plants in the family Rhamnaceae, with five species of spiny shrubs. All species of this genus are native to southern South America. They are non-legume nitrogen fixers.

<i>Chamaebatia</i> Genus of evergreen shrubs in the rose family

Chamaebatia, also known as mountain misery, is a genus of two species of aromatic evergreen shrubs endemic to California. Its English common name derives from early settlers' experience with the plant's dense tangle and sticky, strong-smelling resin. They are actinorhizal, non-legumes capable of nitrogen fixation through symbiosis with the actinobacterium, Frankia.

<i>Trevoa</i> Family of shrubs and trees

Trevoa is a genus of actinorhizal plants; these dicotyledon flora are trees or small shrubs. The genus was first proposed by Miers in 1825, but was not fully described until 1830 by Sir William Jackson Hooker. Genus members are notable for their ability to fix nitrogen. Species of this genus are generally found in the near coastal forests and arid shrubland of South America. Some species are localized in the mountains of central Chile; for example, the species Trevoa trinervis occurs in the La Campana National Park and other proximate areas of central Chile.

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

Phycella is a genus of herbaceous, perennial bulbous flowering plants belonging to the family Amaryllidaceae, subfamily Amaryllidoideae. The genus consists of five species distributed from central Chile to northwestern Argentina.

<i>Tinospora</i> Family of shrubs

Tinospora is a genus of succulent woody climbing shrubs. Thirty-four species are currently recognized. Species generally send down long aerial roots from host trees. They have corky or papery bark. They are found in tropical and sub-tropical parts of Asia, Africa and Australia. The most common species are T. cordifolia and T. crispa.

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