: The group is "artificial" because catkin-bearing evolved convergently. For instance, Salicaceae is now known to be unrelated to the "core" amentiferous plants and is placed in the order Malpighiales.

: Most former Amentiferae (oaks, birches, walnuts) are now placed in the order Fagales , which is part of the Rosid I clade.

: Almost exclusively woody plants, ranging from small shrubs to massive forest trees. Modern Scientific Status

Contemporary research, such as the Angiosperm Phylogeny Group (APG) classification, has dismantled the Amentiferae as a formal taxon:

: Male flowers (and sometimes female) are borne in catkins —tassel-like, often pendulous spikes of reduced flowers.
