New Chromosome Counts in <i>Juncus</i> (Juncaceae) Taxa from Korea

Juncus L. (Juncaceae) is a genus of annual and perennial herbs composed approximately 310 species distributed worldwide, but more rarely found in the tropics. Despite an increasing number karyological studies Juncaceae, reports on chromosome numbers Korean taxa have been scarce owing to small size. Here, we present detailed information obtained from 36 individuals 10 taxa. Chromosome eight (J. diastrophanthus, J. prismatocarpus subsp. leschenaultii, krameri, papillosus, wallichianus, gracillimus, fauriei, setchuensis) are reported for first time. All studied different ploidy variations (2n=30, 60, 80) with chromosomes. These level no systematic relevance taxa; however, this variation might provide additional evidence importance morphological diversification via polyploidization including both auto- allopolyploidization.
