The arums comprise the Family Araceae (including the numerous aroids subfamily): monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe or leaf-like hood. This family of 107 genera and over 3700 species is most diverse in the New World tropics, although also distributed in the Old World tropics and north temperate regions.

In monoecious aroids (posessing separate male and female flowers, but with both flowers present on one plant), the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. In aroids with perfect flowers the stigma is no longer receptive when the pollen is released, thus preventing self-fertilization. There are also some dioecious species.
Anthurium and Zantedeschia are two well-known members of this family, as are Colocasia esculenta (taro) and Xanthosoma roseum (Elephant ear or 'ape). Among the largest inflorescence in the world is that of the arum Amorphophallus titanum (Titan arum). This family includes a great many ornamental plants: Dieffenbachia, Aglaonema, Caladium, Nephthys, and Epipremnum, to name a few. In the genus Cryptocoryne are many popular aquarium plants. Both Taro and Monstera deliciosa provide food value (the fruit of Monstera deliciosa called "Mexican breadfruit"). Philodendron is an important plant in the ecosystems of the rainforests and is often used in home and interior decorating. Symplocarpus foetidus or skunk cabbage is a common North American species.
The largest collection of living material of Araceae is maintained at Missouri Botanical Gardens.
