Yellow Sawah Lettuce

Description:

Limnocharis flava (English: Yellow Sawah Lettuce, Yellow Burr Head or Yellow Velvetleaf,) 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

Habitat:

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
