Root fibrous, with spreading suckers. Stem erect, from two to three feet 

 high, branched, leafy, obtusely angular, hoary, with pubescence, curved 

 downwards. Leaves opposite, spreading, sessile, or nearly so, varying 

 in length from one to two and half inches, and in shape from roundish 

 ovate to oblong lanceolate, with an acute point, and the margin un- 

 equally dentato-serrated, the upper surface veiny, nearly smooth, or 

 hoary, with close pubescence, the under almost white, with soft shaggy 

 hairs. Inflorescence slender terminal spikes, almost cylindrical from 

 the crowded whorls, which are only interrupted towards the base. 

 Bracteas linear, awl-shaped, spreading. Calyx small, slightly striated, 

 the teeth awl-shaped, shaggy, with erect pubescence. Corolla about 

 as long again as the calyx, slightly hairy, pale pink. Stamens about 

 as long as the corolla. Seeds minute, angular, dark brown. 



Habitat, — Waste watery places; not unfrequent in England, less 

 frequent in Scotland and Ireland. 



Perennial ; flowering in August and September. 



The varieties of this species seem to depend upon the diff"erence of 

 soil and situation in which they have grown. They are readily dis- 

 tinguished from all our other species by the slender cylindrical spikes 

 and strongly toothed leaves. The whole plant has a strong peculiar 

 smell.
