GENUS INDEX

GENUS CODE: CYPER
GENUS SCIENTIFIC: Cyperus
GENUS AUTHORITY: L.
GENUS COMMON: Flatsedge
GENUS SUMMARY: A genus of about 600-700 species, herbs, of tropical and warm temperate areas. The circumscription of Cyperus has been expanded recently to include a number of genera found to be phylogenetically embedded within it, notably (for our area), Kyllinga, Lipocarpha, and Oxycaryum (Larridon et al. 2011a, 2011b, 2011c, 2014; Bauters et al. 2014; Reynders 2011).
GENUS IDENTIFICATION: Identification notes: This treatment is closely adapted from Tucker, Marcks, & Carter in FNA (2002b) and other sources. It needs substantial customization and revision prior to publication. Key lead 4 in the main key is problematic.
