Question: Are Okra and Pultenaea both edible tubers?
Context: 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. Okra or okro ( or ), known in many English-speaking countries as ladies' fingers or ochro, is a flowering plant in the mallow family.  It is valued for its edible green seed pods.  The geographical origin of okra is disputed, with supporters of West African, Ethiopian, and South Asian origins.  The plant is cultivated in tropical, subtropical and warm temperate regions around the world. or Labiatae is a family of flowering plants commonly known as the mint or deadnettle family.  Many of the plants are aromatic in all parts and include widely used culinary herbs, such as basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla.  Some species are shrubs, trees (such as teak), or, rarely, vines.  Many members of the family are widely cultivated, not only for their aromatic qualities but also their ease of cultivation, since they are readily propagated by stem cuttings.  Besides those grown for their edible leaves, some are grown for decorative foliage, such as "Coleus".  Others are grown for seed, such as "Salvia hispanica" (chia), or for their edible tubers, such as "Plectranthus edulis", "Plectranthus esculentus", "Plectranthus rotundifolius", and "Stachys affinis" (Chinese artichoke). Bamia matbukha (باميه مطبخ 'cooked okra') or bamia bi-lahm (البامية باللحم 'okra with meat'), often called simply bamia, is a Middle Eastern , Egyptian and Sudanese stew prepared using lamb, okra and tomatoes as primary ingredients.  Additional ingredients used include tomato sauce, onion, garlic, cilantro, vegetable oil, cardamom, salt and pepper.  In Egypt, sinew (tendons) of lamb are typically used, which can endure long cooking times.  Ta'aleya, an Egyptian garlic sauce, is used as an ingredient to add flavor to Bamia.  The word "bamia" itself is simply the Arabic word for okra. Apios americana, sometimes called the potato bean, hopniss, Indian potato, hodoimo, America-hodoimo, American groundnut,or groundnut (but not to be confused with other plants sometimes known by the name groundnut) is a perennial vine that bears edible beans and large edible tubers. Its vine can grow to 1–6 m long, with pinnate leaves 8–15 cm long with 5–7 leaflets.  The flowers are usually pink, purple, or red-brown, and are produced in dense racemes 7.5–13 cm in length.  The fruit is a legume (pod) 5–13 cm long.  Botanically speaking, the tubers are rhizomatous stems, not roots.  Its natural range is from Southern Canada (including Ontario, Quebec, and New Brunswick) down through Florida and West as far as the border of Colorado. Okra soup is prepared using the edible green seed pods of the okra flowering plant as a primary ingredient.  It is greenish in colour.  Okra has a slippery feel when rubbed with the fingers.  The edible green seed pods can also be used in stews. 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. 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. Plectranthus edulis, the Ethiopian potato, known as "Welayta dinich" in Amharic, is a species of annual plant in the Lamiaceae family.  It is indigenous to Ethiopia, where it is grown for its edible tubers.  The tubers are cooked before they are eaten. Pultenaea is a genus of flowering plants in the family Fabaceae-Faboideae that are native to Australia.  They are known commonly as bush peas.
