Philodendron insigne, copyright Bernard Dupont.

Belongs within: Araceae.
Contains: Arisaema.

The Aroideae is a clade within the family Araceae with the spadix (flower-spike) divided into a male and female region. Members of the Aroideae except the Zamioculcadeae are united by the presence of lactifers and of pollen with a thin thin ectexine, thick and spongy endexine and massive intine (Angiosperm Phylogeny Website). Notable members of the clade include taro Colocasia esculenta, widely grown for its edible corms. Many, such as species of Philodendron, are popular ornamental plants grown primarily for their foliage. The titan arum Amorphophallus titanum produces the world's largest unbranched inflorescence, reaching a height of up to 2.5 metres.

Synapomorphies (from the Angiosperm Phylogeny Website, as 'Zamioculcadoideae + Aroideae'): Spathe differentiated into tube plus blade, spadix differentiated into zones with staminate and carpellate flowers; flowers imperfect; pollen inaperturate.
