Salix viminalis | |
Salix viminalis, the basket willow, [2] common osier or osier, is a species of willow native to Europe, Western Asia, and the Himalayas. [3] [4] [5]
Salix viminalis is a multistemmed shrub growing to between 3 and 6 m (9.8 and 19.7 ft) (rarely to 10 m (33 ft)) tall. It has long, erect, straight branches with greenish-grey bark. The leaves long and slender, 10–25 cm long but only 0.5–2 cm broad; they are dark green above, with a silky grey-haired underside. The flowers are catkins, produced in early spring before the leaves; they are dioecious, with male and female catkins on separate plants. The male catkins are yellow and oval-shaped; the female catkins are longer and more cylindrical; they mature in early summer when the fruit capsules split open to release the numerous minute seeds. [3] [4]
It is commonly found by streams and other wet places. The exact native range is uncertain due to extensive historical cultivation; it is certainly native from central Europe east to western Asia, but may also be native as far west as southeastern England. As a cultivated or naturalised plant, it is widespread throughout both Britain and Ireland, but only at lower altitudes. It is one of the least variable willows, but it will hybridise with several other species. [3] [4]
Along with other related willows, the flexible twigs (called withies) are commonly used in basketry, giving rise to its alternative common name of "basket willow". In his History of the Peloponnesian War, the ancient historian Thucydides describes using osier in 425 BCE to construct makeshift shields. [6] Cultivation and use of the common osier was common in England in the 18th and 19th century, with osier beds lining many rivers and streams.
Other uses occur in energy forestry, [3] effluent treatment, wastewater gardens, [7] and cadmium phytoremediation for water purification. [5]
Salix viminalis is a known hyperaccumulator of cadmium, chromium, lead, mercury, petroleum hydrocarbons, organic solvents, MTBE, TCE and byproducts, selenium, silver, uranium, and zinc, [8] [9] and as such is a prime candidate for phytoremediation. For more information, see the list of hyperaccumulators.
Among the most common pathogens on S. viminalis are Melampsora spp. Female plants are more severely infected than male plants. [10] [11]
Willows, also called sallows and osiers, of the genus Salix, comprise around 350 species of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions.
Salix alba, the white willow, is a species of willow native to Europe and western and central Asia. The name derives from the white tone to the undersides of the leaves.
Salix caprea, known as goat willow, pussy willow or great sallow, is a common species of willow native to Europe and western and central Asia.
Salix purpurea, the purple willow, purpleosier willow, or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.
Salix × fragilis, with the common names crack willow and brittle willow, is a hybrid species of willow native to Europe and Western Asia. It is native to riparian habitats, usually found growing beside rivers and streams, and in marshes and water meadow channels. It is a hybrid between Salix euxina and Salix alba, and is very variable, with forms linking both parents.
Salix babylonica is a species of willow native to dry areas of northern China, Korea, Mongolia, Japan, and Siberia but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
Salix pentandra, the bay willow, is a species of willow native to northern Europe and northern Asia. The scientific name refers to the male flowers having five stamens. The English name derives from the resemblance of the leaves to those of the bay laurel; other common names include bay-leaved willow and laurel willow. Its glossy leaves make it more decorative than many other willows, so it is often planted as an ornamental tree.
Salix cinerea is a species of willow native to Europe and western Asia.
Salix miyabeana is a species of willow native to northern Japan. It is a deciduous shrub or small tree, reaching a height of 6–7 m.
Salix udensis is a species of willow native to northeastern Asia, in eastern Siberia, northeastern China, and northern Japan. It is a deciduous shrub growing to 5 m (16 ft) tall. The leaves are slender, lanceolate, 6–10 cm long and 0.8–2 cm broad, glossy dark green above, glaucous and slightly hairy below, with a serrated margin. The flowers are produced in early spring on catkins 2–3 cm long. It typically takes 20 years to reach maturity.
Salix exigua is a species of willow native to most of North America except for the southeast and far north, occurring from Alaska east to New Brunswick, and south to northern Mexico. It is considered a threatened species in Massachusetts while in Connecticut, Maryland, and New Hampshire it is considered endangered.
Salix triandra, with the common names almond willow, almond-leaved willow or black maul willow, is a species of willow native to Europe and Western and Central Asia. It is found from south-eastern England east to Lake Baikal, and south to Spain and the Mediterranean east to the Caucasus, and the Alborz Mountains. It usually grows in riparian habitats, on river and stream banks, and in wetlands.
Salix lanata, the woolly willow, is a subarctic species of willow native to Iceland, the Faeroe Islands and Finland, through to eastern Siberia. In Scotland it can be found in only a few localities of Perthshire, Angus and Aberdeenshire, generally on rocky mountain sides at altitudes of 600–900 m (1,969–2,953 ft).
Salix bebbiana is a species of willow indigenous to Canada and the northern United States, from Alaska and Yukon south to California and Arizona and northeast to Newfoundland and New England. Common names include beaked willow, long-beaked willow, gray willow, and Bebb's willow. This species is also called red willow by Native Americans according to The Arctic Prairies Appendix E by Ernest Tompson Seton.
Salix ligulifolia is a species of willow known by the common name strapleaf willow. It is native to the western United States. It grows in moist and wet habitat, such as riverbanks, swamps, and floodplains, such as in the Sierra Nevada in California.
Salix sitchensis is a species of willow known by the common name Sitka willow.
Salix brachycarpa is a species of flowering plant in the willow family known by the common names barren-ground willow, small-fruit willow and shortfruit willow.
Salix richardsonii is a species of flowering plant in the Salicaceae, or willow family. It is known by the common names Richardson's willow and woolly willow. It is native to Russia and northern North America, where it occurs in Alaska and northern Canada. Some authorities consider it to be a subspecies, Salix lanata subsp. richardsonii(Hook.) A. K. Skvortsov rather than a species itself.
Salix arizonica is a species of willow known by the common name Arizona willow. It is native to the southwestern United States, where it occurs in Arizona, Colorado, New Mexico, and Utah.
Melampsora amygdalinae is a fungal pathogen and part of the division Basidiomycota. It is known as a rust fungus that is host specific. M. amygdalinae commonly infects willows of the genus Salix. This fungus was first discovered in 1909 by Heinrich Klebahn who was a professor of soil biology in Hamburg. Neimi at el. explain how the pathogen occurs throughout the whole distribution of the host, and the small natural populations are an area of interest. This rust fungus is annual and autoecious, which references the fungus spending its entire life in a single host.
