Sparganium glomeratum (Typhaceae): A new record from South Korea

: In this study, we report a new record of the clustered bur-reed Sparganium glomeratum (Laest. ex Beurl.) Beurl., from Yongneup Moor of Daeamsan Mt. in Gangwon-do, Korea. This species is distributed in the cool temperate and circumboreal regions of the Northern Hemisphere. As we recorded this species in a high-altitude wetland, we named it “Du-me-heuk-sam-neung” after the Korean word that translates to “ Sparganium found in deep mountains.” We provide descriptions of the morphological characteristics, photographs, and detailed illustrations of S. glomeratum , as well as a key to allied taxa in Korea.
