Question: Which is a type of flowering plant, Dieffenbachia or Encephalartos?

full_context: Document 1: Dieffenbachia: Dieffenbachia is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands.
Document 2: Encephalartos: Encephalartos is a genus of cycad native to Africa. Several species of "Encephalartos" are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from the Greek words "en" (within), "kephali" (head), and "artos" (bread), referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms.
Document 3: Cycas revoluta: Cycas revoluta (Sotetsu [Japanese ソテツ], sago palm, king sago, sago cycad, Japanese sago palm), is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant.
Document 4: Cycas: Cycas is the type genus and the only genus recognised in the family Cycadaceae. About 113 species are accepted. "Cycas circinalis", a species endemic to India was the first cycad species to be described and was the type of the generic name, "Cycas". The best-known "Cycas" species is "Cycas revoluta". "Cycas" is a very ancient genus of trees. The group achieved its maximum diversity in the Jurassic and Cretaceous periods, when it was distributed almost worldwide. At the end of the Cretaceous, when the non-avian dinosaurs became extinct, so did most of the cycas in the Northern Hemisphere.
Document 5: Dioscorea elephantipes: Dioscorea elephantipes (elephant's foot or Hottentot bread; syn. "Testudinaria elephantipes"), is a species of flowering plant in the genus "Dioscorea" of the family Dioscoreaceae, native to the dry interior of South Africa,
Document 6: Fockea edulis: Fockea edulis is a species of plant in the Apocynaceae family that is native to South Africa and Namibia. A common name is Hottentot bread due to the milky, somewhat sweetish flavour of the edible root which is sometimes gathered from the wild for local use. The plant's latex is said to be poisonous. In Afrikaans the plant is called Bergbaroe, Bergkambroo, Kambaroo, Kambroo, Kambro, or Hotnotswaatlemoen. In Khoi it is called !Koo, !Ku, or !Kuu. A semi-deciduous perennial caudiciform with fat, twisted grey roots, it grows in warmer drier areas, dry savannah and rockery. In the wild, the caudex is partially or totally buried and tends to grow faster this way up to 60 cm in diameter. Fockeas are dioecious, so a male plant and a female plant are needed to produce seeds. The flowers are whitish-green, not very showy but lightly scented, small (0.6-1.5 cm wide) vygie-like flowers surrounded by a large, thick, spider-like calyx. The flowers are pollinated by fruit flies. The plant produces grey-greenish pods. The thin vine branches may reach a length of up to 4 meters, and climb on any type of available support. The leaves are green, entire and oblong. Although it shows decreased activity in the January – April period, it never goes into complete dormancy and always carries some leaves. Plants cannot tolerate more than occasional light frosts with temperatures dropping as low as -2°C. This species is of easy cultivation and hardy when kept reasonably dry and watered only enough to keep the tuber from shriveling.
Document 7: Davallia: "D. polypodiaceae", "D. canariensis", "D. fejeensis" and "D. trichomanoides" are all grown as ornamental plants. "D. fejeensis" is the most common "Davallia" species in commerce, and "D. canariensis" is widely grown as a house plant.
Document 8: Zantedeschia: 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.
Document 9: Monstera: Monstera is a genus of about 50 species of flowering plants in the arum family, Araceae, native to tropical regions of the Americas. The genus is named from the Latin word for "monstrous" or "abnormal", and refers to the unusual leaves with natural holes that members of the genus have.
Document 10: Tacca leontopetaloides: Tacca leontopetaloides is a species of flowering plant in the yam family Dioscoreaceae, that is native to tropical Africa, South Asia, Southeast Asia, northern Australia, New Guinea, Samoa, Micronesia, and Fiji. As an important food source, it was intentionally taken to tropical Pacific Islands with early human migrations. Common names include Polynesian arrowroot, pia (Hawaii, French Polynesia, Niue, and Cook Islands), masoa (Samoa), mahoaʻ a (Tonga), yabia (Fiji) gapgap (Guam) and taka (Indonesia).
Document 11: Dypsis lutescens: Dypsis lutescens, also known as golden cane palm, areca palm, yellow palm, or butterfly palm, is a species of flowering plant in the Arecaceae family, native to Madagascar and naturalized in the Andaman Islands, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Venezuelan Antilles.
Document 12: Dracaena reflexa: Dracaena reflexa, commonly called pleomele or song of India, is a species of "Dracaena" which is a tropical tree native to Madagascar, Mauritius, and other nearby islands of the Indian Ocean. It is widely grown as an ornamental plant and houseplant, valued for its richly coloured, evergreen leaves, and thick, irregular stems.
Document 13: Colocasia: 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.
Document 14: Sago palm: Sago palm is a common name for several plants which are used to produce a starchy food known as sago. Sago palms may be "true palms" in the family Arecaceae, or cycads with a palm like appearance. Sago produced from cyads must be detoxified before consumption. Plants called sago palm include:
Document 15: Spathiphyllum: Spathiphyllum is a genus of about 40 species of monocotyledonous flowering plants in the family Araceae, native to tropical regions of the Americas and southeastern Asia. Certain species of "Spathiphyllum" are commonly known as Spath or peace lilies.
