    How to identify Salix alba:
    · Leaf- you can identify Salix alba by looking at its leaves it has Alternate arrangement, Simple, Lanceolate to narrow ovate shape, it is 2-4 in. in length, finely serrated margin, shiny green above, and nearly white and silky below.
    · Flower- the flower is dioecious, males and females appear as upright, they are yellowish fuzzy catkins, they are 1-1/2-2 in. in length, and they appear before or with the leaves.
    · Fruit- the fruit is a 1-2 in. cluster of valve-like, light brown capsules, containing many fine cottony seeds, and they ripen in late spring to early summer.
    · Stem- very deep red and dry to be a reddish rust
    · Root- It has a fibrous and tap root
    Historical Background:
    The common name of Salix alba is White willow but within it are many cultivars. They are fast-growing but generally are short-lived. They are short lived do to its susceptible diseases caused by the bacterium Brenneria salicis. Another disease Salix alba is prone to is will anthracnose caused by the fungus Marssonina salicicola. The above diseases are serious for trees grown for timber or ornament. It also forms natural hybrids with Crack Will (Salix fragilis) the hybrid is named Salix x rubens Shrank. Hippocrates in the 5th century BC also noted a bitter powder that was synthetically extracted from willow bark the promotion it gave humans was it eased aches and pains and also reduced fevers. A Revered Edmund Stone noted in 1763 that willow bark was effective in reducing or seizing a fever.
    Medicinal Uses:
    In history it has been used to relieve aches and pains and to reduce a fever. Salicin the active extract of bark was isolated to a crystalline form by Henri Leroux (French pharmacist) in 1828 and an Italian chemist by the name Raffaele Piria successfully separated the acid in its pure state. Salicin is like aspirin because it is a chemical derivative of salicylic acid.
