Question: While Rhaphidophora is a genus in the family Araceae, what genus is Cyathodes?
Context: Rhaphidophora is a genus in the family Araceae, occurring from tropical Africa eastwards through Malesia and Australasia to the Western Pacific.  The genus consists of approximately 100 species. Rhaphidophora celatocaulis" is a plant species of the family Araceae. Cyathodes is a genus of shrubs within the heath family.  A characteristic feature of the genus is a deeply five-cleft calyx. Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent.  Some species are widely cultivated and naturalized in other tropical and subtropical regions.  Common names include tarul, karkala ko ganu, elephant-ear, taro, cocoyam, dasheen, chembu, champadhumpa, shavige gadde, and eddoe.  Elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably "Xanthosoma" and "Caladium".  The generic name is derived from the ancient Greek word "kolokasion", which in the Greek botanist Dioscorides (1st century AD) meant the edible roots of both "Colocasia esculenta" and "Nelumbo nucifera".  It is thought that the edible roots of "Colocasia esculenta" have been cultivated in Asia for more than ten thousand years.  The species "Colocasia esculenta" is an invasive species in wetlands along the American Gulf coast, where it threatens to displace native wetland plants. Acorus is a genus of monocot flowering plants.  This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots.  Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae).  However, modern phylogenetic studies demonstrate that "Acorus" is sister to all other monocots.  Common names include calamus and sweet flag. Typhonodorum is a monotypic genus of flowering plants in the family Araceae.  The single species making up this genus is Typhonodorum lindleyanum.  The genus is native to Madagascar, the Comores, Zanzibar, and Mauritius.  This genus is believed to be closely related to "Peltandra" even though "Peltandra" is only found in North America and there don't appear to exist closely related genera in the African mainland.  There isn't fossil evidence to link the two genera so it has been proposed that there once was a genus in Africa from which the two genera had originated.  The African mainland genus spread to North America and to Madagascar 50 million years ago before it broke off.  Then the African genus became extinct and the North American and Madagascan genera remained. Rhaphidophora tetrasperma (common names: "Mini Monstera", Philodendron "Ginny", Philodendron "Piccolo") is a species of plant in the family Araceae, genus "Rhaphidophora".  It is native to Southern Thailand and to Malaysia. Callopsis is a monotypic genus from the plant family Araceae and has only one species, Callopsis volkensii.  This plant forms a creeping rhizome and has cordate-ovate leaves that are medium green and glaborous.  The inflorescence is typical of the Araceae family, with a white spathe and yellow spadix.  The spadix is shorter than the spathe and its male and female flowers are separated shortly. Epipremnum is a genus of flowering plants in the family Araceae, found in tropical forests from China, the Himalayas, and Southeast Asia to Australia the western Pacific.  They are evergreen perennial vines climbing with the aid of aerial roots.  They may be confused with other Monstereae such as "Rhaphidophora", "Scindapsus" and "Amydrium". Zantedeschia is a genus of 8 species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi.  The genus has been introduced on all continents except Antarctica.  Common names include arum lily for "Z. aethiopica" and calla and calla lily for "Z. elliottiana" and "Z. rehmannii", although members of the genus are neither true lilies of Liliaceae, true "Arums", or true "Callas" (related genera in Araceae).  They are also often confused with "Anthurium".  The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
