Question: Which family of the plant Tacca leontopetaloides is the common name for some plant species in the genus "Dioscorea" (family Dioscoreaceae) that form edible tubers?

full_context: Document 1: Dioscorea communis: Dioscorea communis (sometimes placed in the segregate genus "Tamus") is a species of flowering plant in the yam family Dioscoreaceae and is commonly known as black bryony, lady's-seal, and black bindweed.
Document 2: Ficus: is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig ("F. carica") is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses.
Document 3: 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 4: Dioscorea trifida: Dioscorea trifida is a species of flowering plant in the family Dioscoreaceae. It is a species of yam (genus "Dioscorea"). It is native to the Caribbean and Central and South America. Its many common names include Indian yam, cush-cush, and yampee. It is called mapuey in Venezuela, inhame in Brazil, tabena and ñame in Colombia, sacha papa in Peru, and ñampi in Costa Rica.
Document 5: Pandanus tectorius: Pandanus tectorius is a species of "Pandanus" (screwpine) that is native to Malesia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include Tahitian screwpine, thatch screwpine., hala tree; pandanus, and pu hala in Hawaiian. The fruit is sometimes known as hala fruit.
Document 6: Apios fortunei: Apios fortunei, commonly known as Hodo, Hodoimo, groundnut, or potatobean, is a tuber-forming member of the Bean family. It is a native plant of Eastern China and Japan. It is one of three species in the genus "Apios" that are known to produce edible tubers, although it has generally been considered an emergency, or famine food or medicinal plant. A study done on the chemical composition of the tubers found that starch was the predominate carbohydrate, although smaller amounts of sucrose and glucose were found and almost no fructose was found. In the wild, "Apios fortunei" is often found near brooks. "Apios fortunei" is a perennial climbing vine. The leaves are pinnate with 3-7 leaflets and are ovate or lanceolate in shape, 3–7 cm long. Flowers have been variously described as whitish-green, light yellowish-green with a red purple edge on the wing petal, or sulphurous green with rosy wing petals. The flowers form pseudoracemes or terminal panicles, 6–26 cm long. The flowers are showy and have ornamental potential. Legume fruits are linear, 7–8 cm long and 5–6 mm wide.
Document 7: Dioscorea orangeana: Dioscorea orangeana, is a tuberous vining flowering plant in the genus "Dioscorea", endemic the Forêt d’Orangea near Antsiranana in Madagascar, from which it derives its name. The tuber is possibly edible, and unlike most other "Dioscorea" species, the tuber has many finger-like lobes as opposed to a single tuber. Because the plant is new to science and the possible harvesting by local populations, the conservation status of "Dioscorea orangeana" is of great concern.
Document 8: Chinese yam: Chinese yam ("Dioscorea polystachya"), also called cinnamon-vine, is a species of flowering plant in the yam family. This perennial climbing bine native to China now grows throughout East Asia (Japan, Korea, Kuril Islands, Vietnam). It is believed to have been introduced to Japan in the 17th century or earlier. Introduced to the United States as early as the 19th century for culinary and cultural uses, it is now considered an invasive plant species. The plant was introduced to Europe in the 19th century during the European Potato Failure, where cultivation continues to this day for the Asian food market. The edible tubers, often called nagaimo or Chinese-potato, are cultivated largely in Asia and sometimes used in alternative medicine. This species of yam is unique as the tubers can be eaten raw.
Document 9: Inocarpus fagifer: Inocarpus fagifer, commonly known as the Tahitian chestnut, Polynesian chestnut, aila or mape tree, is a species of flowering plant in the subfamily Faboideae of the legume family, Fabaceae. The tree has a wide range in the tropics of the south-west Pacific and south-east Asian regions, and a history of traditional use by the peoples of Polynesia and Melanesia. It is the only edible and culturally important member of the genus "Inocarpus".
Document 10: Colocasia esculenta: Colocasia esculenta is a tropical plant grown primarily for its edible corms, the root vegetables most commonly known as taro. It is believed to be one of the earliest cultivated plants. Linnaeus originally described two species which are now known as "Colocasia esculenta" and "Colocasia antiquorum" of the cultivated plants that are known by many names including eddoes, dasheen, taro and madumbi, but many later botanists consider them all to be members of a single, very variable species, the correct name for which is "Colocasia esculenta".
Document 11: 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 12: 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 13: Dioscorea: Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It is named after the ancient Greek physician and botanist Dioscorides.
Document 14: Yam (vegetable): Yam is the common name for some plant species in the genus "Dioscorea" (family Dioscoreaceae) that form edible tubers. Yams are perennial herbaceous vines cultivated for the consumption of their starchy tubers in many temperate and subtropical world regions. The tubers themselves are also called "yams", having numerous cultivars.
Document 15: Tuber: Tubers are enlarged structures in some plant species used as storage organs for nutrients. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. "Stem tubers" form from thickened rhizomes (underground stems) or stolons (horizontal connections between organisms). Common plant species with stem tubers include potato and yam. Some sources also treat modified lateral roots ("root tubers") under the definition; these are encountered in sweet potato, cassava, and dahlia.
