Perennial ; stem 6 to 3 ft., erect or base decumbent, rarely as stoat at the base 

 as a goose-quill, usually sleuder; nodes often bearded. Leaves 4-8 in., narrow, 

 smooth or scaberulous, floral scabrid with tubercled margins, upper glabrous or

 or longer. — Very variable in stature, length of leaves and habit of the panicle.
