Echinochloa oryzoides (Ard.) Fritsch is one of major troublesome weeds in the paddy fields in Korea. The Korean name and scientific name of the species has been controversial among researchers. The Korean names 'Nonpee' and 'Gangpee' are being used interchangeably and the application of its scientific name is being confused. The committee composed of the Korea National Arboretum and the Korean Society of Plant Taxonomists has agreed in the use of 'Nonpee' as the Korean name. Therefore, we suggest to use the agreed name of the species for researchers to avoid confusion. In addition, the application of scientific names is also confused with E. oryzoides (Ard.) Fritsch and E. oryzicola (Vasinger) Vasinger. E. oryzicola (Vasinger) Vasinger should be applied to the known 'Nonpee' and E. oryzoides (Ard.) Fritsch should be applied to the unrecorded 'Nadononpee' discovered in Masan, Gyeongsangnam-do.
