Quick Summary

Salicaceae, commonly known as the willow family, is a group of trees and shrubs belonging to the order Salicales. This family is widespread globally, with the exception of New Zealand, and is particularly prevalent in tropical regions. The family includes well-known genera such as Salix (willows) and Populus (poplars).12

Key characteristics of Salicaceae include alternate leaves, often with toothed margins, and flowers that are typically small and apetalous, arranged in catkins. Many species, like willows and poplars, can reproduce vegetatively from stems placed in wet ground, and aspens are known to sprout from roots after forest fires. The seeds of willows and poplars are small and possess tufts of hair that aid in their dispersal.12

Species within this family are valued for various purposes, including ornamental use, shade, erosion control, and timber. The compound salicin, found in certain willows, is the source of salicylic acid, used in pain relievers. Some species, like the common osier (S. viminalis), provide twigs used for basket making. Additionally, certain tropical members of the family have medicinal uses, such as Casearia sylvestris for treating leprosy and wounds, and its twigs are used as chew sticks in West Africa.32
