Quillworts recently collected from a population on Cheju Island, South Korea, are tetraploid (2n = 44 = 22II) and have cristate megaspores and echinate microspores. Based on these characters, the specimens are identified as Isoetes sinensis var. sinensis, a globally rare taxon previously unreported in Korea. The apparently close taxonomic relationship between Korean I. sinensis var. sinensis and the basic diploid I. taiwanensis suggests that further phylogenetic investigation is warranted.
