Abstract：
:Carex (Cyperaceae) is one of the largest genera of the flowering plants, and comprises more than 2,000 species. In Carex, section Siderostictae with broader leaves distributed in East Asia is thought to be an ancestral group. We aimed to clarify the phylogenetic relationships and chromosomal variations within the section Siderostictae, and to examine the relationship of broad-leaved species of the sections Hemiscaposae and Surculosae from East Asia, inferred from DNA sequences and cytological data. Our results indicate that a monophyletic Siderostictae clade, including the sections Hemiscaposae, Siderostictae and Surculosae, as the earliest diverging group in the tribe Cariceae. Low chromosome numbers, 2n = 12 or 24, with large sizes were observed in these three sections. Our results suggest that the genus Carex might have originated or relictly restricted in the East Asia. Geographical distributions of diploid species are restricted in narrower areas, while those of tetraploid species are wider in East Asia. It is concluded that chromosomal variations in Siderostictae clade may have been caused by polyploidization and that tetraploid species may have been able to exploit their habitats by polyploidization.
