Limnocharis flava (English: Yellow Sawah Lettuce, Yellow Burr Head or Yellow Velvetleaf, Indonesian: genjer, Javanese: gènjèr, Lao Phak Khan Chong, Tagalog: cebolla de chucho, Thai: ตาลปัตรฤาษี, Vietnamese: Kèo nèo or cù nèo) is a species of aquatic flowering plant which is native to Southeast Asia. It is a roughly 50 cm tall plant 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.[1]

Yellow Burr Heads grow 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.[2]

As food

Traditionally this plant is an important vegetable in parts of Indonesia, Philippines, Vietnam,[3] Laos, Isan (Thailand)[4] and parts of India, where the central flower stalk and the leaves are used in soups, curries, salads and stir-fries.[5] 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.[6]

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.[7]
