''Limnocharis flava'' ((英語:yellow sawah lettuce, yellow burr head or yellow velvetleaf), (インドネシア語:genjer), (ジャワ語:gènjèr), Lao ''phak khan chong'', (タガログ語:cebolla de chucho), (タイ語:ตาลปัตรฤาษี), khmer: ត្រកៀតប៉ោង, (ベトナム語:kèo nèo) or ''cù nèo'') is a species of aquatic flowering plant which is native to Mexico, Central America, South America, Cuba, Haiti and the Dominican Republic but widely naturalized in southern and southeastern Asia (India, Sri Lanka, Assam, Cambodia, Burma, Thailand, Vietnam, Indonesia, Malaysia and southern China (Guangdong, Yunnan)).〔(Kew World Checklist of Selected Plant Families, ''Limnocharis flava'' )〕〔(Flora of China v 23 p 89, ''Limnocharis flava'' )〕 ''Limnocharis flava'' is roughly 50 cm tall. growing in clumps. Its triangular-shaped leaves and hollow stems are glabrous. Its inflorescences have a very characteristic shape, producing three-lobed yellow flowers about 1.5 cm in diameter. The fruits are spherical. Although it is not a floating plant, its seeds are carried away by currents.〔(ISSG - ''L. flava'' )〕〔Buchenau, Franz Georg Philipp. 1868. Abhandlungen herausgegeben vom Naturwissenschaftlichen Vereine zu Bremen 2: 2,4. ''Limnocharis flava''〕 Yellow velvetleaf grows generally wherever there is not very deep stagnant fresh water, in swampy areas. It sometimes invades rice fields where it can become a weed. As an invasive species it has become a pest in some wetlands in other parts of the world.〔〔(Environmental Pests- Australia )〕 ==As food== Traditionally this plant is an important vegetable in parts of Indonesia, Philippines, Vietnam,〔(Micronutrient composition and nutritional importance of gathered vegetables in Vietnam )〕 Laos, Isan (Thailand)〔(Thailand Illustrated - Healthy Food )〕 and parts of India, where the central flower stalk and the leaves are used in soups, curries, salads and stir-fries.〔(Stir-Fried Genjer (Limnocharis Flava) )〕 The immature flower buds are also eaten. Owing to its flat taste, in some areas it is considered "poor people's food" or emergency food, eaten whenever there is not much else left. This characteristic was put into song by Muhammad Arief, in the 1940s hit ''Genjer-genjer'' in the Banyuwangi language in Java.〔(Gendjer Gendjer )〕 In Thailand it is also known as ''phak khan chong''. In Isan the ''Limnocharis flava'' leaf is eaten raw with ''nam phrik''. It is known as ''phak phaai'' (ผักพาย) with a long "ā" sound, not to be confused with ''phak phai'' (ผักไผ่), the leaves of ''Persicaria odorata'', another type of edible leaf.〔(New Thai Plant name index )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Limnocharis flava」の詳細全文を読む スポンサード リンク
