Heart-leaved willow

Description

Salix eriocephala, known as heart-leaved willow or Missouri River willow, is a species of willow native to a large portion of the temperate United States and Canada. It is usually found as a narrow shrub or small tree with multiple trunks growing to a height of 20 ft (6.1 m). It has dark gray, scaly bark with thick lance-shaped leaves that are hairy underneath. The silky catkins appear before the leaves in early spring. The willow genus or willow genus (Salix) is a genus in the willow family, and grows as trees, shrubs, rice or herbaceous dwarf shrubs. The trees in the genus are usually called willow trees, while the more shrub-like species are usually called willow. Otherwise, arrows are usually called the species that have flowering and leaf splitting at the same time, while species that bloom on bare twigs are called willow. The genus has over 400 species. The grayish bark of the wood is smooth or rough and with a wood that often has ridges under the bark. Its winter buds have a bud scales and the leaves are strewn, simple and notched or finely sawn. The willow is a two-story building with flowers gathered in axillary pendants. Fertilizers of willow species have been found in tertiary strata in Europe, Asia and in Arctic regions, and these older species are often close to now living tropical willow species with many stamens. In older Quaternary deposits, modern northern varieties of willow are beginning to emerge. Traces of willow have been found in Italy and in Europe's pre- and postglacial peat layers of several today alpine and arctic species such as dwarf willow, net willow and polar willow. Willow occurs mainly in temperate areas in the Northern Hemisphere. In 2009, according to the Swedish Board of Agriculture, there were 36 willow species in Sweden, most in the north. The most well-known species in Sweden are willow (S. caprea), gray willow (S. cinerea) and willow (S. fragilis). Knowledge is difficult to determine the species when hybrids occur. Several cultivated species have been naturalized, such as white willow (S. alba), red willow (S. purpure) and basket willow (S. viminalis).
