A new species, Fimbristylis jindoensis J. Kim & M. Kim, is herein named and described. It is found on wet lowland mountain slopes in Jindo-gun, Jeollanam-do, Korea. Fimbristylis jindoensis shares several characteristics (long-creeping rhizomes, oblong spikelets, brown scales, and three-sided achenes) with the related species F. pierotii Miq. It is, however, distinct from F. pierotii, which has terete culms with five to six furrows that are 9-48 cm tall, flowers in June to July, a dry grassland habitat, fewer than ten spikelets, and simple anthela inflorescences. In contrast, the new species has shallow furrowed oval culms which are 57-93 cm tall, flowers in July to August, a wet mountain habitat, more than twenty spikelets, and compound anthela inflorescences.
