Chromosome number of <i>Carex brevispicula</i> (Cyperaceae), a sedge endemic to Korea

<i>Carex brevispicula</i> (Cyperaceae) is endemic to Korea and characterized by constricted achenes, short lateral spikes, awned staminate pistillate scales. The species classified in sect. <i>Mitratae</i> occurs throughout South Korea, perennating on mountains and/or rocky slopes under half shadow conditions. Meiotic chromosomes of the were examined this study, which 33 meiotic cells from seven populations found be less than 2 μm long with non-constricted (<i>n</i> = 34<sub>II</sub>). stable chromosome number may related narrow geographical distribution distinct achene morphology. Further investigations distribution, morphological character variation, characteristics should conducted closely taxa understand derivation its endemism Korea.
