Rhus - Sumac

Latin plant name Rhus Common plant name Sumac Plant type Flowering shrub Size (meters) <1 - 10 m Distinguishing features The leaves are spirally arranged. Rhus chinensis compounds possess strong antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal and antioxidant activities.

Salix - Willow

Latin plant name Salix Common plant name Willow Plant type Tree Size (meters) <5-15 m Distinguishing features Found primarily on moist soils in cold and temperate regions of the Northern Hemisphere. They came to Ireland right after the melting of the ice age thanks to their light seeds that can be blown by the wind, along with the grasses and the beerchs. Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft usually pliant tough wood, slender branches and large fibrous often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to life, and roots readily grow from aerial parts of the plant. The leaves are typically elongated, but may also be round to oval, frequently with a serrated margin. Most species are deciduous; semievergreen willows. Willows are dioecious, with male and female flowers appearing as catkins on different plants; the catkins are produced early in the spring, often before the leaves, or as the new leaves open. Basic crafts, such as baskets, fish traps, wattle fences and wattle and daub, house walls, were often woven from osiers. Willow wood is also used in the manufacture of boxes, brooms, cricket bats (grown from certain strains of white willow), cradle boards, chairs and other furniture, dolls, flutes, poles, sweat lodges, toys, turnery, tool handles, veneer, wands and whistles.

Alnus - Alder

Latin plant name Alnus Common plant name Alder (alisos) Plant type Tree Size (meters) <20-40 m Distinguishing features With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, These trees differ from the birches (Betula, the other genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. Alder leaves and sometimes catkins are used as food by numerous butterflies and moths. Alder bark contains the anti-inflammatory salicin, which is metabolized into salicylic acid in the body. As a hardwood, alder is used in making furniture and cabinets and other woodworking products.

Acer - Maple

Latin plant name Acer Common plant name Maple Plant type Tree Size (meters) <10-45 m Distinguishing features The word Acer derives from a Latin word meaning "sharp" (compare "acerbic"), referring to the characteristic points on maple leaves. Most species are deciduous, but a few in southern Asia and the Mediterranean region are evergreen. Most are shade-tolerant Maples are distinguished by opposite leaf arrangement. The leaves in most species are palmate veined and lobed. A maple leaf is on the coat of arms of Canada, and is on the Canadian flag. The maple is a common symbol of strength and endurance and has been chosen as the national tree of many countries including Canada. Maples are planted as ornamental trees Some of the larger maple species have valuable timber. Maple is considered a tonewood, or a wood that carries sound waves well, and is used in numerous musical instruments

Ginkgo biloba

Latin plant name Ginkgo biloba Common plant name Ginkgo Plant type Tree Size (meters) <20- 30 m Distinguishing features The ginkgo is a living fossil, as a unique species recognisably similar to fossils dating back 270 million years. Native to China, the tree is widely cultivated and introduced early in human history, and has various uses as a food and in traditional medicine. The tree has an angular crown and long, somewhat erratic branches, and is usually deep rooted and resistant to wind and snow damage. During autumn, the leaves turn a bright yellow, then fall, sometimes within a short space of time (one to 15 days). A combination of resistance to disease, insect-resistant wood and the ability to form aerial roots and sprouts makes ginkgos long-lived, with some specimens claimed to be more than 2,500 years old. Ginkgo is a relatively shade-intolerant species that (at least in cultivation) grows best in environments that are well-watered and well-drained. The leaves are unique among seed plants, being fan-shaped with veins radiating out into the leaf blade. Ginkgos are dioecious, with separate sexes, some trees being female and others being male. Male plants produce small pollen cones with sporophylls, each bearing two microsporangia spirally arranged around a central axis. Female plants do not produce cones. Two ovules are formed at the end of a stalk, and after pollination, one or both develop into seeds.

Araucaria - Monkey puzzle

Latin plant name Araucaria Common plant name Monkey puzzle Plant type Conifer evergreen tree Size (meters) < 40 m Distinguishing features Because of the species' great age it is sometimes described as a living fossil. Araucaria araucana is the national tree of Chile. The leaves are thick, tough and scale-like, triangular, 3–4 cm long, 1–3 cm broad at the base, and with sharp edges and tip. They persist for 10–15 years or more, so cover most of the tree except for the older branches. It is usually dioecious, with the male and female cones on separate trees, though occasional individuals bear cones of both sexes. The male (pollen) cones are oblong and cucumber-shaped, 4 cm long at first, expanding to 8–12 cm long by 5–6 cm broad at pollen release. The tree is wind pollinated. The female (seed) cones, which mature in autumn about 18 months after pollination, are globose.

Leylandis

Latin plant name Cupressus x leylandii Common plant name Leylandii Plant type Coniferous evergreen tree Size (meters) < 15 m Distinguishing features Rapid and thick growing. Leyland Cypress is light-demanding but is tolerant of high levels of pollution and salt spray. A hardy, fast-growing natural hybrid, it thrives on a variety of soils and sites are commonly planted in gardens to provide a quick boundary or shelter hedge, because of their rapid growth. Although widely used for screening, it has not been planted much for forestry purposes.

Digitalis - Foxglove

Latin plant name Digitalis Common plant name Foxglove Plant type Herbaceous perennial shrub Size (meters) <50-255 cm Distinguishing features The scientific name means "finger-like" and refers to the ease with which a flower of Digitalis purpurea can be fitted over a human fingertip. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. A group of medicines extracted from foxglove plants are called Digitalin. Digitalis toxicity (Digitalis intoxication) results from an overdose of digitalis and causes anorexia, nausea, vomiting and diarrhoea, as well as sometimes resulting in xanthopsia (jaundiced or yellow vision) and the appearance of blurred outlines (halos). Bradycardia also occurs. Because a frequent side effect of digitalis is reduction of appetite, some individuals have used the drug as a weight-loss aid.

Laburnum - Golden chain

Latin plant name Laburnum Common plant name Golden chain Plant type Decidious tree Size (meters) < 2 m Distinguishing features All parts of the plant are poisonous, and can be lethal if consumed in excess. Symptoms of laburnum poisoning may include intense sleepiness, vomiting, convulsive movements, coma, slight frothing at the mouth and unequally dilated pupils. In some cases, diarrhea is very severe, and at times the convulsions are markedly tetanic. The main toxin in the plant is cytisine, a nicotinic receptor agonist. They have yellow pea-flowers in pendulous racemes 10–30 cm (4–12 in) long in spring, which makes them very popular garden trees.

Gunnera
