Flowers bisexual or unisexual, regular, perigynous; perianth with 4–many segments in 1–several whorls, segments petaloid or sepaloid; stamens 4–many, opening by valves from the base upwards, sometimes with apical appendages; staminodes present or absent; carpels numerous, free, usually enclosed in the enlarged unilocular receptacle; ovule 1 per locule. Fruit an aggregate of achenes, sometimes retained within the expanded receptacle; seeds with copious endosperm.

Atherospermataceae is sometimes included as a subfamily in a broadly defined Monimiaceae (Cronquist 1981; Philipson 1993). However, Atherospermataceae is now generally recognised as a distinct family.
