Salix fragilis is a scientific name that has historically been used for two different willows:
Willows, also called sallows and osiers, from the genus Salix, are around 400 species of deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions of the Northern Hemisphere.
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 × 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, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
The Caha Mountains are a range of low sandstone mountains situated on the Beara peninsula in south-west County Cork, in Ireland. The highest peak is Hungry Hill, 685 m (2,247 ft) tall. Other notable peaks include Knocknagree, Sugarloaf Mountain, Eskatarriff, Knocknaveacal, Derryclancy, Nareera, Killane Mountain and Baurearagh Mountain.
Coleophora lusciniaepennella is a moth of the family Coleophoridae. It is found in most of Europe, except the Iberian Peninsula, the Mediterranean islands and most of the Balkan Peninsula and Russia. It occurs in forest-steppe biotopes.
S. fragilis may refer to:
Stigmella nivenburgensis is a moth of the family Nepticulidae. It is found from Lithuania and central Russia to the Iberian Peninsula, Italy and Greece. It has also reported from Turkmenistan.
Stigmella obliquella is a moth of the family Nepticulidae which feeds on willow and can be found in Asia and Europe. It was first described by Hermann von Heinemann in 1862.
Leucoptera sinuella is a moth in the Lyonetiidae family. It is found in most of Europe, except Ireland, the Balkan Peninsula and the Mediterranean Islands. It is also found in Japan and North Africa.
Phyllonorycter connexella is a moth of the family Gracillariidae. It is found from Fennoscandia to the Pyrenees and Italy and from France to central Russia and Ukraine.
Phyllonorycter salicifoliella is a moth of the family Gracillariidae. It is widespread across North America, from Mississippi to Ontario in the east and from southern California to northern British Columbia in the west.
Phyllocnistis saligna is a moth of the family Gracillariidae. It is known from almost all Europe, as well as India, Sri Lanka, La Réunion and South Africa.
Caloptilia stigmatella is a moth of the family Gracillariidae. It is known from the Holarctic Region, including all of Europe.
Synanthedon flaviventris, the sallow clearwing, is a moth of the family Sesiidae. The larvae form pear-shaped galls on sallows.
Aculus laevis is a species of mite which causes galls on the leaves of sallows. It was first described by Alfred Nalepa in 1892.
Salix euxina, the eastern crack-willow, is a species of flowering plant in the willow family Salicaceae, native from Turkey to the Caucasus. It was first described by I. V. Belyaeva in 2009. It is one of the parents of the common crack-willow, Salix × fragilis.
