Western Black Willow Tree
The Western Black Willow (S. lasiandra, Benth.) grows to be a tree 60 feet high on river banks and lake shores from British Columbia to California and east into Montana, Colorado and New Mexico. The type becomes modified in the remote limits of its range. The leaves are 4 or 5 inches long, lanceolate and finely cut-toothed; they are a dark, lustrous green above, paler or glaucous below.
