Abstract: | The Cyperaceae are well known for having a large amount of variation in chromosome numbers both within and among genera. Most
of this variation has been previously attributed to agmatoploid or qualitative aneuploid chromosome number change. To date
there have been 4,231 reported chromosome number counts in the family. Despite the large number of counts made, they only
represent approximately 16% of the species currently recognized. These counts are here presented in an indexed list with standardized
nomenclature following a draft copy of the World Checklist of Cyperaceae. Additionally, I explore variation within genera
where a significant number of counts have been made. Given the distributions of counts within genera there is evidence for
both agmatoploid and polyploid chromosome number changes. |
