Biennial. June, July. 



Root spindle-shaped, thick, with many whorled fibres. Stem 2 or 3 

 feet high, hollow, stout, furrowed, half immersed in the water, very 

 bushy, with numerous, spreading, leafy branches. Leaves stalked, 

 spreading, repeatedly pinnate, cut, with innumerable, fine, ex- 

 panded, dark-green, shining, acute segments. Umbels opposite 

 to the leaves, on shortish tumid stalks, many-rayed, without 

 any general bracteas. Partial umbels very dense, of numerous 

 short rays, accompanied by many narrwv, taper-pointed brac- 

 teas. Fl. white, numerous } the outer ones largest, and most 

 irregular ; the innermost more certainly prolific. Fr. ovate, ra- 

 ther compressed, purplish, very smooth, crowned with the 

 spreading calyx, and rather short, permanent, slightly spread- 

 ing, styles. Each seed has 5 broad, tumid, scarcely corky ribs, 

 separated by narrow furrows, and agrees better with the usual 

 character of CEnanthe than the last species, which nevertheless 

 cannot be separated from the rest. 

 Pr. Roth always writes the old name Phelandrium ; which agi-ees 

 with an etymology 1 have hazarded in Rees's Cyclopaedia, v. 27, 

 from <pri\£tv, to be treacherous, alluding to the poisonous nature 

 of the plant. ^ryXAcij, cork, is not at all satisfactory.
