Limnocharis flava is roughly 50 centimetres (20 in) 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.[5][6]
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.[4][7]
As food
editTraditionally this plant is an important vegetable in parts of Indonesia, the Philippines, Vietnam,[8] Laos, Isan (Thailand)[9] and parts of India, where the central flower stalk and the leaves are used in soups, curries, salads and stir-fries.[10] The immature flower buds are also eaten. In Isan the leaf is eaten raw with nam phrik. 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.[11]
