Shrub, tree; dioecious (monoecious). Stem: trunk < 40 m; wood soft; bark smooth, bitter; buds scaly. Leaf: simple, alternate, deciduous; stipules generally present, deciduous or not, often large. Inflorescence: catkin [or various, or flowers 1]; each flower subtended by 1 bract. Flower: perianth modified into non-nectariferous, cup- or saucer-shaped structure or reduced to adaxial nectary (rarely also with abaxial nectary, then free or fused into shallow cup). Staminate flower: stamens 2–many. Pistillate flower: pistil 1, ovary superior to 1/2-inferior, chambers generally 2–4, placentas parietal, stigma lobes 2–4. Fruit: berry, drupe, or 2–4-valved capsule. Seed: often with basal tuft of hairs.
58 genera, 1210 species: widespread in tropics, northern temperate, arctic. Now including many genera (e.g., Flacourtia, Idesia, Xylosma) formerly in Flacourtiaceae, at least in part because of presence on leaf margins in both families of salicoid teeth (vein extending to tooth tip). In California (and generally outside California), Populus pollinated by wind, Salix by insects, wind. Hybrids common; identification often difficult. —Scientific Editor: Thomas J. Rosatti.
