Wolffia globosa

provided by wikipedia EN

Wolffia globosa is a species of flowering plant known by the common names Asian watermeal and duckweed. It is native to Asia and is found in parts of the Americas, where it may be native or naturalized. It grows in mats on the surface of calm, freshwater bodies, such as ponds, lakes, and marshes. It is a very tiny, oval-shaped plant with no leaves, stems, or roots. The body of the plant, a transparent green frond, is less than a millimeter wide. In one human experiment, processed W globosa was reported to provide dietary protein and vitamin B12.[1]

Wolffia globosa has been described as the world's smallest flowering plant, at 0.1–0.2 mm (0.004–0.008 in) in diameter.[2][3]

Known in Thai as Pham (ผํา), it is a popular item in Thai cuisine, especially in Isan.[4]
