Description: Trees or shrubs, pubescent or glabrous.
Leaves simple or more usually 1-foliolate with a swelling at apex of petiole at junction with lamina; the margins commonly toothed, sometimes entire; venation usually prominently reticulate. Leaves often turning red before falling.
Inflorescence a raceme, often ramiflorous or borne amongst the leaves at end of branches. Flowers usually bisexual, sometimes polygamous, 4- or 5-merous. Petals usually finely divided into linear lobes. Stamens numerous, anthers often awned, dehiscing by apical slits; anthers mostly much longer than the filament.
Fruit a drupe, usually blue, sometimes black; stone often deeply sculptured and called a 'quandong'.
