Buckthorn
Buckthorn is a group of evergreen shrub species with small, inconspicuous flowers. These plants grow throughout North America in moist, open areas with nutrient-rich soil. They all produce fruit that is red or black and in the shape of a drupe. There is some taxonomic contention in the scientific community surrounding this genus.
Nakedwoods
Nakedwoods is a genus of about 30 species of flowering plants in the buckthorn family, Rhamnaceae, native to warm temperate to tropical regions. It has the snake-like stems or stamens. The species are shrubs and small trees growing 1.006 to 10 m tall, with simple ovate leaves. The flowers are small, greenish-white or yellowish; the fruit is a capsule containing three seeds.
Supplejacks
Supplejacks are a genus of some thirty or so climbing plants and trees that are native to Asia, Africa, and the Americas. Many species are grown in gardens. Climbing species are valued for their evergreen foliage. Species that grow as trees have broad crowns that make them a good choice of shade tree and they are also grown as windbreaks. This genus is named for the noted French botanist M. Berchem.
Gouania
The 50 to 70 species it contains are native to tropical and subtropical regions of the world. They are shrubs or lianas.
Berchemiella
Berchemiella includes two species, one found in China and another in Japan.
Colletia
Colletia is a genus of flowering plants in the family Rhamnaceae, with 15 to 17 species of spiny shrubs. All species of this genus are native to southern South America.
Discaria
Discaria is a genus of about 12 species of flowering plants in the family Rhamnaceae, native to temperate regions of the Southern Hemisphere, in Australia, New Zealand and South America. They are deciduous thorny shrubs or small trees growing to 2 to 5 m tall.
Paliurus
Paliurus are shrubs or small trees growing to 3 to 15 m tall. The shoots are zig-zagged, with a leaf and two stipular spines on the outside of each kink. The leaves are deciduous or evergreen, oval, 2 to 10 cm long and 1 to 7 cm broad, glossy green, with three conspicuous veins at the base, and an entire or bluntly toothed margin. The fruit is a dry woody nutlet centred in a circular wing 1 to 3.5 cm diameter. The eight species are native to warm, dry regions of Eurasia and North Africa from Morocco and Spain east to Japan and China.
Pomaderris
Pomaderris is a genus of shrub to small tree in the buckthorn family Rhamnaceae. A distinctive feature of the leaves, branches, and twigs of this genus, is that they are hairy. Sixty-five of the species are native to Australia and the other five are from New Zealand.
Buckthorns
This plant is similar to common buckthorn, but the stems are more stout and the leaves are longer. In its native range it may be up to 10 meters tall. It may also reach up to 9 meters in cultivation. The oppositely arranged leaves are up to 13 cm long by 6 wide in its native range, and usually smaller where it is introduced.
Jujube
Jujube are small trees with inconspicuous flowers. Some of the trees in this genus produce fruit similar to dates, which has made them extremely popular with both humans and birds and are now widely cultivated across the world. The Ziziphus genus got its name from the Persian words zizfum or zizafun, which were used to designate jujube plants.
Adolphia
Adolphia contains only two species. These are rigid, thorny, flowering bushes found in North America.
Trichocephalus
Krugiodendron
Krugiodendron are evergreen trees that grow in the Carribbean and Central America. These species are resistant to some hurricane-force winds, making them a popular choice with landscapers. Krugiodendron produce tiny whitish-green blooms in the spring, but the trees are cultivated for their foliage. They produce attractive glossy green leaves.
Scutia
Alphitonia
Redroots
Redroots are commonly cultivated as ornamental plants in gardens. The seeds generally require a forest fire to trigger their germination, and the flowers are extremely fragrant. The leaves of these plants are an important food source for deer, porcupine, and quail, and the dried leaves have also been used in teas.
Bluewoods
Bluewoods are thorny bushes with a similar growth habit, often forming dense stands in open areas. These bushes grow from seeds, and some species of bluewoods are easily recognized by their large, football-shaped fruits. Other species produce fruits covered in small thorns.
Phylica
It contains about 150 species, the majority of which are restricted to South Africa, where they form part of the fynbos. A few species occur in other parts of southern Africa, and on islands including Madagascar, the Mascarene Islands, Île Amsterdam, Saint Helena, Tristan da Cunha, and Gough Island.
Mock buckthorn
Mock buckthorn produce small flowers, but it’s the multicolored trunk that makes these shrubs easy to identify. They are primarily found in the American southwest growing in canyons and desert grasslands. Mock buckthorn are also an occasional landscaping plant used to create hedges and borders.
Spyridium
Cryptandra
Sarcomphalus
Sarcomphalus are a small group of plants native to the tropical and subtropical Americas. These plants are well adapted to hot and arid environments, with long spines, small leaves, and a compact growth habit. Some of these plants are in decline and the species Sarcomphalus havanensis is listed as 'endangered' on the IUCN Red List of endangered species.
Hovenia
Hovenia is a small genus of deciduous trees or shrubs in the family Rhamnaceae. They occur naturally from India to Japan.
Alder buckthorns
The alder buckthorns are a group of shrubs that are sometimes used for wildlife habitat, wildlife food sources (leaves and berries), erosion control, woodworking, and as ornamental plants. The species F. alnus is best known for its use in manufacturing gun powder due to its very even burn rate.
Rhamnella
Ventilago
Ventilago is a genus of plants in the family Rhamnaceae. It includes about 35 species found in the tropics of Australasia, with one species each in Africa and Madagascar.
Alpine laurels
Alpine laurels is a genus of flowering plants in the buckthorn family, Rhamnaceae.
