Schoenoplectus gemmifer C. Sato, T. Maeda & Uchino was found to occur in Jingning She Autonomous County in Zhejiang Province, China. This represents a new record of this species from China. The species is similar to Schoeno-plectus mucronatus, but differs from the latter in its caulis soft texture, shorter spikelets, style 2, asexual reproduction buds on caulis, and its chromosome number was 2n = 78 ± 2 (while 2n = 44 for S. mucronatus). It has great academic value to research the relationship between China and Japan as a special and rare species in Japan.
