Sallow, or Withen, Salix caprcata, L. is an indigenous species of the willow, which, though it will vegetate in damp situations, requires a drier ground than any other of that genus. In a good soil, it attains the height of thirty feet. - The tender shoots and suckers of this tree are, on account of their flexible nature, useful for baskets and wicker-work. - In Sweden, the young rind is not only employed with advantage by tanners, but also by dyers, for striking a deep black on linen-yarn, in combination with alder-bark. The former has likewise been profitably converted into Paper. - See vol.iii. p. 335.
