Cyperus ovatus Baldwin

PINEBARREN FLATSEDGE

**

This is a taxonomically difficult group, and Godfrey & Wooten (1979: 262) state "C. retrorsus, as here conceptualized, is a polymorphic complex [that] we fail to be able satisfactorily to delimit segregate taxa specifically or subspecifically" and that it is "sometimes difficult to distinguish from and perhaps grades into, C. [croceus]". They did not mention the name C. ovatus. Several entities may be recognized (Tucker et al. 2002: 183-184, 187; Reid et al. 2014). An ITS phylogeny investigated some relationships (Reid et al. 2014).
