I've always called that sawgrass. I have no real reason to call it that,
but the stuff that grew in my field that looked like that had rough
edges on the leaves. Someone told me that sawgrass was common in this
area (Eastern MA) and there were very few things that fit that name, so
I settled on this one. It was a minor weed, easily controlled by
pulling.
