In marshes, especially near the sea. 



Perennial. July, August. 



Root with many whorled fibres. Stem branched, leafy, angular, 

 furrowed, often zigzag, sometimes of a tawny red, from 1 to 2 

 feet high. Leaves stalked, linear, acute, entire, flat, not undu- 

 lated. Fl. very numerous, in dense leafy whorls, very n^ar to- 

 gether, and finally confluent, assuming, like the whole plant, a 

 rich tawny-golden hue, very conspicuous. The petals, as the 

 seeds ripen, become dilated, triangular, fringed at each side with 

 about 4 bristle-like teeth, exceeding their own length, and 

 spreading widely, giving the whole dense cluster a hairy ap- 

 pearance. Each petal bears a large, tawny, very prominent, ob- 

 long, not globular, tubercle. The seeds are acutely triangular, 

 very small.
