marginal flowers usually staminate. Bracts cuneate or obovate, 
abruptly pointed, fuscous above and white bearded, receptacle 
smooth, flowers about 14 lines high, the outer sterile perianth 
tubular below and its lobes at some distance from the inner, all 
bearded at the apex. The gland is borne sometimes on the 
bract and both pairs of segments, and sometimes only on the 
upper pair. One of the upper pair is generally larger than the 
other. Fertile flowers scarcely more than half the size of the 
sterile, the pairs of perianth segments without a tube, and much 
nearer together than the sterile, all densely bearded. 
Still, shallow water, ponds and streams, Newfoundland to 
Ontario, New England and Minnesota, south to Florida and Texas. 
Occurs in Great Britain. July to October.

L. gnaphalodes, Mx. F1. ii. 165 (1803), and American authors
