https://en.wikipedia.org/wiki/Salicaceae All members of the family are trees or shrubs that have simple leaves with alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all exhibit salicoid teeth; a salicoid tooth being one in which a vein enters the tooth, expands, and terminates at or near the apex, near which are spherical and glandular protuberances called setae. Members of the family often have flowers which are reduced and inconspicuous, and all have ovaries that are superior or half-inferior with parietal placentation.

Dvinamiai medžiai, krūmai arba krūmokšniai su paprastais pražanginiais lapais. Žiedai žirginėliuose, su pažiedėmis. Vaisius – vienalizdė dėžutė, kuri suskyla į 2-4 dalis. Sėklos smulkios, su ilgais plaukeliais, dėl to vėjas jas lengvai išplatina. Lietuvoje auga dviejų genčių augalai: gluosnis (Salix) ir tuopa (Populus).
