Stock (probably the offset of the pre- 

 vious autumn) emitting creeping run- 

 ners, with a cluster of fibrous roots, 

 usually more or less thickened into ob- 

 long tubers. Stems thick and very hol- 

 low, erect, 2 to 3 feet high, and slightly 

 branched. Radical leaves twice pinnate, 

 with small cuneate segments divided 

 into 3 or 5 lobes ; those of the stem have 

 long stalks, hollow like the stems, and 

 bear only in their upper extremity a few 

 pinnate segments with linear lobes. Um- 

 bels terminal, the central one on the 

 main stem has only 3 rays, each with 

 numerous sessile fertile flowers, and few 

 or no pedicellate barren ones ; those 

 which terminate the branches have 

 usually 5 rays, their flowers all pedicel- 

 late and barren. Partial involucres of 

 a few small narrow bracts, the general 

 one either entirely wanting or reduced to a single bract. Fruits in 

 compact globular heads, each one full 2 lines long, narrowed at the 

 base, and crowned by the stiff, narrow teeth of the calyx, and the still 

 longer, rigid styles. 



In wet meadows and marshes, dispersed over temperate Europe, 

 extending eastward to the Caucasus, and northward into southern 

 Sweden. Common in England and Ireland, but only in the southern 

 counties of Scotland. FL summer and autumn.
