In ditches, and the margins of rivers, on a gravelly soil. 



Perennial. June, July. 



Root tuberous, horizontal. Herb smooth, cellular, half immersed 

 in w^ater. Leaves erect, narrow, acute, near a yard high. Stalk 

 solitary, still taller, round and very smooth. Umbel 4 inches, 

 or more, in diameter, interspersed with many lanceolate, brown- 

 ish bracteas. Fl. very handsome, rose-coloured, erect, each 

 about an inch broad, without scent. Blair, in the book above 

 quoted, calls the 3 outer petals a calyx ; but the whole six are 

 permanent, and so firmly connected, that perhaps they had 

 better all be termed a coloured calyx.
