Monochoria vaginalis var. angustifolia (Pontederiaceae) was newly found in a furrow in Imha-ri, Boeun-gun, Chungcheongbuk-do for the first time in Korea. This taxon is distinguished from the other species of the genus Monochoria in Korea by having the smallest plant height, very narrow lanceolate leaves, a cuneate leaf base, and raceme with 1 to 2 flowers. A local name was newly given, ``Ga-neun-moul-dal-ge-bi`` for the species. The morphological characteristics and illustrations of the taxon as well as photographs at the habitat are provided with a taxonomic key to the species of Monochoria in Korea.
