Alocasia macrorrhizos is a species of flowering plant in the arum family (Araceae) that it is native to rainforests of Maritime Southeast Asia, New Guinea, and Queensland [1] and has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics. Common names include giant taro, [3] giant alocasia, ʻape, biga, [4] and pia. [5] In Australia it is known as the cunjevoi [5] (a term which also refers to a marine animal). Alocasia macrorrhizos has many varieties both wild and cultivated. The largest of these is the naturally occurring A. m. Borneo Giant which is endemic to Borneo which has huge sagitate leaves (laminae) twelve to fifteen feet (3.7 to 4.6 meters) in length by about eight feet (2.5 meters) wide on stalks (petioles) six to eight feet ( 1.8 to 2.5 meters) long, forming a rosette at the top of a massive succulent trunk up to 18 inches (46 cm) thick and up to five feet (1.5 meters) high. The spatheate inflorescence is pink, and resembles the Pink Calla (Zantedeschia rehmannii) [6] [7]
The giant taro was originally domesticated in the Philippines, but are known from wild specimens to early Austronesians in Taiwan. From the Philippines, they spread outwards to the rest of Maritime Southeast Asia and eastward to Oceania where it became one of the staple crops of Pacific Islanders. [8] [9] They are one of the four main species of aroids (taros) cultivated by Austronesians primarily as a source of starch, the others being Amorphophallus paeoniifolius , Colocasia esculenta , and Cyrtosperma merkusii , each with multiple cultivated varieties. Their leaves and stems are also edible if cooked thoroughly, though this is rarely done for giant taro as it contains higher amounts of raphides which cause itching. [10] [11]
The reconstructed word for giant taro in Proto-Austronesian is *biRaq, which became Proto-Oceanic *piRaq. Modern cognates in Maritime Southeast Asia and Micronesia include Rukai vi'a or bi'a; Ifugao bila; Ilocano, Cebuano, and Bikol biga; Tiruray bira; Ngaju biha; Malagasy via; Malay and Acehnese birah; Mongondow biga; Palauan bísə; Chamorro piga; Bima wia; Roti and Tetun fia; Asilulu hila; and Kowiai fira. In Oceania, cognates for it include Wuvulu and Aua pia; Motu and 'Are'are hira; Kilivila and Fijian via; and Hawaiian pia. Note that in some cases, the cognates have shifted to mean other types of taro. [12] [8]
Indigenous Australian names included pitchu in the Burnett River (Queensland); cunjevoi (South Queensland); hakkin Rockhampton (Queensland); bargadga or nargan of the Cleveland Bay. [13] The Yugarabul word for the plant, bundal, [14] is also where the name of the suburb Boondall is derived from.
It is edible if cooked for a long time but its sap irritates the skin due to calcium oxalate crystals, or raphides which are needle like. [15] Plants harvested later will have more raphides. [16] Alocasia species are commonly found in marketplaces in Samoa and Tonga and other parts of Polynesia. The varieties recognized in Tahiti are the Ape oa, haparu, maota, and uahea. The Hawaiian saying: ʻAi no i ka ʻape he maneʻo no ka nuku (The eater of ʻape will have an itchy mouth) means "there will be consequences for partaking of something bad". [17]
The giant heart-shaped leaves make impromptu umbrellas in tropical downpours.
Anthelme Thozet in 1866 documented the method of preparation: "The young bulbs, of a light rose colour inside, found growing on large old rhizomes, are scraped, divided into two parts, and put under hot ashes for about half an hour. When sufficiently baked, they are then pounded by hard strokes between two stones – a large one, Wallarie, and a small one, Kondola. All the pieces which do not look farinaceous, but watery when broken, are thrown away; the others, by strokes of the Kondola, are united by twos or threes, and put into the fire again ; they are then taken out and pounded together in the form of a cake, which is again returned to the fire and carefully turned occasionally. This operation is repeated eight or ten times, and when the hakkin, which is now of a green-greyish colour, begins to harden, it is fit for use." [18] : 14
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe. Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
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.
Corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Dioscorea alata – also called ube, 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.
Xanthosoma is a genus of flowering plants in the arum family, Araceae. The genus is native to tropical America but widely cultivated and naturalized in other tropical regions. Several are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, cocoyam, tannia, tannier, yautía, macabo, ocumo, macal, taioba, dasheen, quequisque, ʻape and as Singapore taro. Many other species, including especially Xanthosoma roseum, are used as ornamental plants; in popular horticultural literature these species may be known as ‘ape due to resemblance to the true Polynesian ʻape, Alocasia macrorrhizos, or as elephant ear from visual resemblance of the leaf to an elephant's ear. Sometimes the latter name is also applied to members in the closely related genera Caladium, Colocasia (taro), and Alocasia.
Pandanus is a genus of monocots with about 578 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm and screw pine. They are classified in the order Pandanales, family Pandanaceae.
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.
Calophyllum inophyllum is a large evergreen plant, commonly called tamanu, oil-nut, mastwood, beach calophyllum or beautyleaf. It is native to the Old World Tropics, from Africa through Asia to Australia and Polynesia. Due to its importance as a source of timber for the traditional shipbuilding of large outrigger ships, it has been spread in prehistoric times by the migrations of the Austronesian peoples to the islands of Oceania and Madagascar, along with other members of the genus Calophyllum. It has since been naturalized in regions of the East African coast. It is also a source of the culturally important tamanu oil.
Amorphophallus paeoniifolius, the elephant foot yam or whitespot giant arum, is a tropical plant native to Island Southeast Asia. It is cultivated for its edible tubers in Southeast Asia, South Asia, Madagascar, New Guinea, and the Pacific islands. Because of its production potential and popularity as a vegetable in various cuisines, it can be raised as a cash crop.
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. Common names include Polynesian arrowroot, Fiji arrowroot, East Indies arrowroot, pia, and seashore bat lily.
Alocasia odora, also known as night-scented lily, Asian taro or giant upright elephant ear, is a species of flowering plant native to East and Southeast Asia. Traditionally, A. odora is sometime used as a medicine for the treatment of the common cold in Vietnam.
Proto-Austronesian is a proto-language. It is the reconstructed ancestor of the Austronesian languages, one of the world's major language families. Proto-Austronesian is assumed to have begun to diversify c. 4000 BCE – c. 3500 BCE in Taiwan.
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.
Xanthosoma sagittifolium(Tannia) is a tropical flowering plant from the family Araceae. It produces an edible, starchy corm. X. sagittifolium is native to tropical America where it has been first cultivated. Around the 19th century, the plant spread to Southeast Asia and Africa and has been cultivated there ever since. X. sagittifolium is often confused with the related plant Colocasia esculenta (Taro), which looks very similar and is also used in a similar way. Both plants are often collectively named Cocoyam.
Leucocasia gigantea, also called the giant elephant ear or Indian taro, is a species of flowering plant. It is a 1.5–3 m tall aroid plant with a large, fibrous corm, producing at its apex a whorl of thick, green leaves. It is the sole species in genus Leucocasia.
Alocasia cucullata is a species of flowering plant in the arum family known by the common names Chinese taro, Chinese ape, Buddha's hand, and hooded dwarf elephant ear. It is kept as an ornamental plant.
Syngonium podophyllum is a species of aroid that is a popular houseplant. Common names include: arrowhead plant, arrowhead vine, arrowhead philodendron, goosefoot, nephthytis, African evergreen, and American evergreen. The species is native to a wide region of Latin America from Mexico through Bolivia, and naturalized in the West Indies, Florida, Texas, Hawaii, and other places.
Lūʻau, Luʻau, Laulau, Lū, Rourou, Rukau, Fāfā, Hāhā, and Palusami are all related dishes found throughout Polynesia based on the use of taro leaves as a primary ingredient. While taro generally is known as a root vegetable for its starchy corms, the leaves are consumed as well. The base recipe is vegetarian. Most often, coconut milk was added, and later meat or seafood. The texture of the dish range from a thick soup to a dense cake.
Alocasia robusta is a gigantic herb of the arum family (Araceae) which is endemic to the island of Borneo. The plant is a rosette herb consisting of several very large leaves having a sagittate lamina or blade up to twelve feet long by eight feet wide, borne on very stout petioles or stalks up to 12 feet in length. More recently, Anthony Lamb of the Sabah Agricultural Department found and measured one individual with a lamina fifteen feet in length., the largest leaf of any non-palm. The inflorescence is the spathe and spadix typical of the Arum family, with the spathe being a very dark blackish-purple color. This species was unknown to science prior to 1967. The plant is usually trunkless.
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.
