Tacca leontopetaloides is a species of flowering plant in the yam family Dioscoreaceae. It is native to the islands of Southeast Asia. Austronesian peoples introduced it as a canoe plant throughout the Indo-Pacific tropics during prehistoric times. It has become naturalized to tropical Africa, South Asia, northern Australia, and Oceania. [2] Common names include Polynesian arrowroot, Fiji arrowroot, East Indies arrowroot, pia, [4] and seashore bat lily. [5]
Polynesian arrowroot is an ancient Austronesian root crop closely related to yams. It is originally native to Island Southeast Asia. It was introduced throughout the entire range of the Austronesian expansion during prehistoric times (c. 5,000 BP), including Micronesia, Polynesia, and Madagascar. Polynesian arrowroot have been identified as among the cultivated crops in Lapita sites in Palau, dating back to 3,000 to 2,000 BP. [6] It was also introduced to Sri Lanka, southern India, and possibly also Australia through trade and contact. [7]
Polynesian arrowroot was a minor staple among Austronesians. The roots are bitter if not prepared properly, thus it was only cultivated as a secondary crop to staples like Dioscorea alata and Colocasia esculenta . Its importance increased for settlers in the Pacific Islands, where food plants were scarcer, and it was introduced to virtually all the inhabited islands. They were valued for their ability to grow in low islands and atolls, and were often the staple crops in islands with these conditions. In larger islands, they were usually allowed to grow wild and were useful only as famine food. Several cultivars have been developed in Polynesia due to the centuries of artificial selection. The starch extracted from the root with traditional methods can last for a very long time, and thus can be stored or traded. [6] The starch can be cooked in leaves to make starchy puddings, similar to the use of starch extracted from sago palms ( Metroxylon sagu ). [8] Due to the introduction of modern crops, it is rarely cultivated today. [6]
The tubers are round, hard and potato-like, with a brown skin and white interior. [4] [5] In December, the plant is dormant, the leaves and stalks dry up and die down to the ground until March when new leaves grow back. [9] : 387
The leaves are "palmately incised and/or divided into 3-13 lobes, each lobe pinnately divided into numerous smaller ones". [9] : 401 Several petioles 17–150 cm (6.7–59.1 in) in length extend from the center of the plant which look like giant celery, on which the large leaves (30–70 cm or 12–28 in long and up to 120 cm or 47 in wide) are attached. [5] The leaf's upper surface has depressed veins, and the under surface is shiny with bold yellow veins.
Flowers are borne on tall stalks in greenish-purple umbel-like clusters surrounded by large bracts with long whisker-like appendages, their function is unknown. Each single flower has long, threadlike bracteoles 1 cm long. [4] [5]
The fruit emerges from the bracts, each fruit are globular 4–5 cm long. [4] [5] The fruits ripen and turn from pale or dark green to pale orange. Each fruit produces many flat, ribbed and yellowish brown seeds 5–8 mm long. [9] : 378
The tubers of Polynesian arrowroot contain starch, making it an important food source for many Pacific Island cultures, primarily for the inhabitants of low islands and atolls. Polynesian arrowroot was prepared into a flour to make a variety of puddings. The tubers are first grated and then allowed to soak in fresh water. The settled starch is rinsed repeatedly to remove the bitter taste from taccalin, a kind of poisonous substance, and then dried. [9] : 387 The flour was mixed with mashed taro, breadfruit, or pandan fruit extract and mixed with coconut cream to prepare puddings. In Hawaii, a local favorite is haupia, which was originally made with pia flour, coconut cream and kō (cane sugar). [10] Today, Polynesian arrowroot has been largely replaced by cornstarch.
The starch was additionally used to stiffen fabrics, and on some islands, the stem's bast fibres were woven into mats.
In traditional Hawaiian medicine the raw tubers were eaten to treat stomach ailments. Mixed with water and red clay, the plant was consumed to treat diarrhea and dysentery. This combination was also used to stop internal hemorrhaging in the stomach and colon and applied to wounds to stop bleeding. [4]
Tapioca is a starch extracted from the tubers of the cassava plant, a species native to the North and Northeast regions of Brazil, but whose use is now spread throughout South America. It is a perennial shrub adapted to the hot conditions of tropical lowlands. Cassava copes better with poor soils than many other food plants.
Sago is a starch extracted from the pith, or spongy core tissue, of various tropical palm stems, especially those of Metroxylon sagu. It is a major staple food for the lowland peoples of New Guinea and the Maluku Islands, where it is called saksak, rabia and sagu. The largest supply of sago comes from Southeast Asia, particularly Indonesia and Malaysia. Large quantities of sago are sent to Europe and North America for cooking purposes. It is traditionally cooked and eaten in various forms, such as rolled into balls, mixed with boiling water to form a glue-like paste (papeda), or as a pancake.
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.
Maranta arundinacea, also known as arrowroot, maranta, West Indian arrowroot, obedience plant, Bermuda arrowroot, araru, araruta, ararao or hulankeeriya, is a large, perennial herb found in rainforest habitats of the Americas, but cultivated in tropical regions worldwide.
Dioscorea alata – also called ube, ubi, purple yam, or greater yam, among many other names – is a species of yam. The tubers are usually a vivid violet-purple to bright lavender in color, but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato beniimo (紅芋), however D. alata is also grown in Okinawa. With its origins in the Asian tropics, D. alata has been known to humans since ancient times.
Po‘e or poke is a Polynesian pudding usually eaten as a dessert.
Taro is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures. Taro is believed to be one of the earliest cultivated plants.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.
The genus Tacca, which includes the batflowers and arrowroot, consists of flowering plants in the order Dioscoreales, native to tropical regions of South America, Africa, Australia, Southeast Asia, and various Oceanic islands. In older texts, the genus was treated in its own family Taccaceae, but the 2003 APG II system incorporates it into the family Dioscoreaceae. The APG III and APG IV systems continue to include Tacca in Dioscoreaceae.
Dioscorea esculenta, commonly known as the lesser yam, is a yam species native to Island Southeast Asia and introduced to Near Oceania and East Africa by early Austronesian voyagers. It is grown for their edible tubers, though it has smaller tubers than the more widely-cultivated Dioscorea alata and is usually spiny.
Dioscorea trifida is a species of flowering plant in the family Dioscoreaceae. It is a species of yam. 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.
Fijian cuisine has long consisted of primarily foraged and farm-grown food. Although rice, wheat, and tea all became staples during Fiji's colonial era, native Fijians still eat primarily tubers and coconuts. The cuisine of Fiji is known for its seafood and various green vegetables, including ''ota'', a young forest fern, and ''bele'', a plant that resembles spinach.
A great variety of cassava-based dishes are consumed in the regions where cassava is cultivated. Manihot esculenta is a woody shrub of the spurge family, Euphorbiaceae, native to South America, from Brazil, Paraguay and parts of the Andes.
Nigeria is by far the world’s largest producer of yams, accounting for over 70–76 percent of the world production. According to the Food and Agriculture Organization report, in 1985, Nigeria produced 18.3 million tonnes of yam from 1.5 million hectares, representing 73.8 percent of total yam production in Africa. According to 2008 figures, yam production in Nigeria has nearly doubled since 1985, with Nigeria producing 35.017 million metric tonnes with value equivalent of US$5.654 billion. In perspective, the world's second and third largest producers of yams, Côte d'Ivoire and Ghana, only produced 6.9 and 4.8 million tonnes of yams in 2008 respectively. According to the International Institute of Tropical Agriculture, Nigeria accounted for about 70 percent of the world production amounting to 17 million tonnes from land area 2,837,000 hectares under yam cultivation.
Pascuense cuisine, otherwise known as Easter Island cuisine or Rapa Nui cuisine incorporates the influences of the indigenous Rapa Nui people and Latin America. Notable ingredients include seafood such as fish, octopus (heke), eel, sea snails (pipi) and crustaceans (lobster), as well as sweet potato, taro, banana, pineapple, coconut, pumpkin, and poultry, pork and lamb meat.
Arrowroot is a starch obtained from the rhizomes (rootstock) of several tropical plants, traditionally Maranta arundinacea, but also Florida arrowroot from Zamia integrifolia, and tapioca from cassava, which is often labeled arrowroot. Polynesian arrowroot or pia, from Palawan-Philippines arrowroot ("uraro/araro"), and Japanese arrowroot, also called kudzu, are used in similar ways. In Odisha, India, it is called ପାଳୁଅ (Paḷua).
Arrowroot is to an edible starch obtained from several tropical plants.
Dioscorea dumetorum, also known as the bitter yam, cluster yam, trifoliate yam, or three-leaved yam, is a species of flowering plant in the yam family, Dioscorea. It is native to sub-Saharan Africa and especially common in the tropical regions of West Africa, including Nigeria, Benin, and Ghana. D. dumetorum has both toxic and non-toxic varieties.
One of the major human migration events was the maritime settlement of the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 BP. These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger ships and catamarans that enabled early Austronesians to thrive in the islands of Maritime Southeast Asia, Near Oceania (Melanesia), Remote Oceania, Madagascar, and the Comoros Islands.
