have a few narrow linear segments, partial involucre either wanting 

 or of a number of linear lanceolate segments. Floicers while or 

 pinkish, irregular, the outer ones barren, bearing only the rudiments 

 of styles, having also narrower longer more pungent segments to the 

 calyx. Calyx of five nearly equal narrow lanceolate segments. 

 Petals inversely heart-shaped, or obovate, notched, with a small in- 

 flexed point, unequal, especially the outer ones. Stamens on long 

 slender filaments, with small purplish anthers. Styles long, with 

 small obtuse stigmas. Disk small, conical, crowning the somewhat 

 pear-shaped fruit, which are crowded together with a roundish rough 

 looking head. Carpels with five ridges, the two lateral ones forming 

 the margins rather wider than the rest, which are pale and obtuse. 

 Albumen on a transverse section, convex, or roundish. 



Habitat. — Ditches, rivulets, and watery places ; frequent. 



Perennial; flowering in July and August.

 British Flora, vol. i. p. 131.— Lindley, Synopsis, p. 119. 



Root wiih several fleshy tapering tubercles, intermixed with branched 

 filiform fibres. Stem erect, round, smooth, striated, from one to three 

 feet high, slightly branched and leafy. Leaves smooth, bi-pinnate, 

 alternate, on long striated footstalks, dilated at the base and sheathing, 

 the root leaves with wedge-shaped cut leaflets, mostly trifid, the upper 

 ones are long, linear, simple, while the intermediate ones are ovate 

 oblong, and sometimes with a crenated margin. Umbels lateral and 

 terminal, the general of numerous angular striated equal rays, the 

 partial of numerous crowded short somewhat unequal ones. General 

 involucre of several narrow linear unequal spreading segments, and 

 the partial ones generally more numerous than these. Floicers while 

 or pinkish, somewhat irregular. Calyx of five nearly equal lanceolate 

 teeth. Petals five, unequal, especially on the outer flowers, inversely 

 heart-shaped, or ovate and notched with a small inflexed point. 

 Stamens with long slender filaments and small roundish anthers. 

 Styles at first short, becoming longer, straight, rigid, with an obtuse 

 small stigma and conical base. Fruit crowded into roundish heads, 

 cylindrical, narrower at the base, and somewhat contracted beneath 

 the calyx. Carpels smooth, with five prominent obtuse ridges, the 

 lateral ones forming the margins somewhat wider than the others. 

 Channels with single rather large vitta. Alhiunen roundish, some- 

 what flat in front.
