A linear classification of Cyperaceae.

This paper provides a linear classification of two subfamilies, 24 tribes, 10 subtribes and 95 genera of the monocot family Cyperaceae (Poales), based on a stable phylogenetic framework resulting from years of morphological, molecular phylogenetic and phylogenomic studies. The family includes c. 5687 species. The most species-rich tribes are the monogeneric tribe Cariceae with c. 2003 species, and tribe Cypereae with c. 1131 species. The highest generic diversity is found in tribe Schoeneae (25 genera), which resulted in the recognition of eight subtribes to facilitate studying this group. The linear classification will help the organisation of Cyperaceae specimens in herbaria according to a systematic order and provides an easy-to-use summary of the current classification of the family.
