hiding in plain sight

i have nothing interesting to say about bristly sedge except that it is somewhat odd looking, an i have no idea why i have never noticed it before now. wetlands have lots of plants with long narrow leaves like this, so that would be easy to overlook, but none of them have visible fists of fat, bristly fingers like this. STILL learning in year ten, with no end in sight.
