In ditches, ponds, and other watery places, common. 



Perennial. Juhj, August. 



Root tuberous, propagating itself by runners. Stems erect, rising 

 2 or 3 feet above the water, round, hollow, tumid, striated, 

 smooth, glaucous. Radical leaves under water, doubly pinnate, 

 with flat, wedge-shaped, lobed leojlets; stem-leaves on long, 

 tumid, sheathing stalks, hollow as well as their cylindrical com- 

 pound leajiets. Umbels on long, hollow, lateral and terminal 

 stalks, the lower ones of 3, the upper of several, general raijs, 

 with rarely one or two, almost capillary, general hracteas. Par- 

 tial umbel's of very numerous raijs, those of the disk short, bear- 

 ing fertile ^oirer*- ; of the circumference still more abundant, 

 and longer, bearing hc\.rren Jlowers, with rudiments only of styles. 

 In fruit the partial umbels are globose, bristly with the long rigid 

 st7jles, which are very little swelled at the base. Fruit turbinate, 

 abrupt, with intermediate ribs, the principal ones not very pro- 

 minent or turgid. 



The variety (3 of Hudson, and of Fl. Br., indicated by the figures of 

 Morison, Dodonaeus, and Petiver's n. 6, differs very slightly in 

 size only, and that merely accidentally.
