Not possible to identify to species from this photo alone. More likely to be A nodosa, as that is more common in the area, but also A nitida. These are all closely related and often hard to distinguish without having the physical specimen

TYVM grassman. I take more shots now to make it easier to ID.

Some things to photograph to tell between nodosa-scabra-nitida
leaf sheaths mostly narrower in scabra (2-5 mm) than nitida-nodosa (4.5-9 mm)
leaf blades mostly narrower in scabra (0.6-1.2 mm) than nitida-nodosa (1-3 mm)
useful to have a ruler to show dimensions
Flowerheads somewhat contracted/usually denser (but open at anthesis) and stem nodes mostly concealed by the sheaths in nitida
Flowerheads usually sparse and stem nodes exposed in nodosa
But there are a lot of specimens in herbaria which can't be assigned to a particular species due to the overlap in features
