Dieffenbachia, commonly known as dumb caneorleopard lily, is a genus of tropical flowering plants in the family Araceae.

Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands.
Xanthosoma is a genus of flowering plants in the arum family, Araceae. The genus is native to tropical America but widely cultivated and naturalized in other tropical regions. Several are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, cocoyam, tannia, tannier, yautía, macabo, ocumo, macal, taioba, dasheen, quequisque, ʻape and as Singapore taro. Many other species, including especially Xanthosoma roseum, are used as ornamental plants; in popular horticultural literature these species may be known as ‘ape due to resemblance to the true Polynesian ʻape, Alocasia macrorrhizos, or as elephant ear from visual resemblance of the leaf to an elephant's ear. Sometimes the latter name is also applied to members in the closely related genera Caladium, Colocasia (taro), and Alocasia.

There are only two species in the genus and both are extremely rare. These two species are Alloschemone occidentalis and Alloschemone inopinata.

Urospatha is a genus of flowering plants in the family Araceae that consists of approximately 10 known species. They are found growing in South America and Central America in swamps, wet savannahs, and brackish water. The leaves of the species in this genus are upward pointing and sagittate (arrow-shaped). The inflorescences are quite unique; the spathe is mottled and elongated with a spiral twist at the end. The seeds are distributed by water and have a texture similar to cork that allows them to float. They also quickly germinate in water.

The tribe Spathicarpeae is named after the genus Spathicarpa.
Scaphispatha is a genus of flowering plants in the family Araceae. It contains two species, S. gracilis and S. robusta. The genus was believed to be monotypic until 2003 when a new species, S. robusta was discovered by Eduardo Gomes Gonçalves in northern Brazil. The plant had been grown in cultivation for some years, but had always been assumed to be a Caladium until it flowered.
