 Cyperus planifolius Richard

 

Distribution: Southern U.S. to Mesoamerica

Habitat:  Maritime, dunes and other seashore habitats

Recognition:  Similar to Cyperus ligularis:

1. Spikelets 3-7 mm long; spikes usually < 1.5 cm diam., inland or seashore…C. ligularis (Spikelets becoming brownish vs. remaining green in C. retorsus) 

1. Spikelets 6-22 mm long; spikes > 1.5 cm diam., seashore…C. planifolius  Achene 1.3-2

Cyperus planifolius might also be confused at a glance with Bolboschoenus robustus, which, however, has much thicker spikelets 6-10 mm in diamter (vs. 2-4 mm).
