 the others scattered, the lowest often remote, all on short or 

 long peduncles and erect, or sometimes the one or two lower 

 ones spreading; densely or loosely flowered; bracts leafy, 

 partly sheathing, mostly exceeding the culm ; perigynia ovate, 

 obovate or suboval, nerved, with a short, abruptly bent, or long
