The genus name Limnocharis is derived from the Greek limno (meaning marsh or pond) and charis (meaning grace) (Haynes and Holm-Nielson 1992) and flava is Latin for yellow. The genus is generally accepted to have two species, Limnocharis flava (Linneaus) Buchenau 1868 and L. laforestii (Duchass. ex Griseb) 1858. L. flava was first named Alisma flava by Linneaus in 1753 (Haynes and Holm-Nielsen 1986). Since then, other synonyms have included Damasonium flavum Mill. 1772, Limnocharis emarginata Humb. & Bonpl. 1808, Limnocharis plumieri Rich. 1815, Limnocharis laforestii Duchas. ex Griseb (1858) and Limnocharis mattogrossensis O. Ktze. (1893) (Woodson and Schery 1943).
Due to the use of L. flava as an edible leaf vegetable, it has many local names across tropical Asia. Common names for L. flava include limnocharis, yellow burr head (or bur-head), yellow velvet leaf, yellow sawah lettuce, sawah flowering rush, velvetleaf, cebolla de chucho, cu neo, keo neo, manja payal, paku rawan, water cabbage, kengkong, kalami, enceng, lumur, genger and gunda (Kays and Silva Dias 1995, GISD 2010). Kays and Silva Dias (1995) list many local names of L. flava in Mandarin, Arabic, Malay, Indonesian, Portuguese, Spanish and English. In this review L. flava will be referred to as limnocharis.
