Root large, thick, woody. The whole plant quite smooth. Stem 

 erect, from one to two feet high or more, branched, especially above. 

 Leaves pinnate, with a terminal leaflet ; the rest opposite, sometimes 

 alternate, each ovate, cordate at the base, strongly serrated, green above* 

 paler beneath, with a strongish midrib and numerous branching veins' 

 at the base of almost every footstalk is a small toothed stipule, larger in 

 some, smaller or entirely wanting in others ; the radical leaves with long 

 stalks, those of the stem much shorter. Inflorescence a terminal, dense, 

 ovate spike, of a dark dull purple hue, on long naked stalks. Spikes 

 generally about an inch long, but very various in size, the upper flowers 

 expanding first. Perianth single ; the limb of four dark-red or purple* 

 ovate, spreading segments ; its tube investing the germen, and having 

 at its base a greenish, four-scaled, ciliated bractea. Nuts one, or rarely 

 two, enclosed in the tube, and crowned by the persistent limb of the 

 perianth. 



Habitat. — Rather moist limestone or clayey countries, especially iu 

 the North of England. Less frequent in the Lowlands of Scotland. 



Perennial ; flowering in June and July. 



This plant does not appear to possess either the medicinal or agricul. 

 tural properties for which at one time it was thought valuable ; it is 

 bitter and somewhat astringent, and not a food rawch relished by cattle^
