Root with fibrous tufts and long spreading suckers. Stem erect, 

 square, simple, from twelve to eighteen inches high, more or less 

 clothed with deflexed pubescence. Leaves ovate lanceolate, heart- 

 shaped or truncated at the base, the margins coarsely and more or less 

 unequally serrated, hairy, deep green above, paler beneath, spotted 

 with white, or marked with white blotches, the lower ones on long foot- 

 stalks, the upper nearly sessile. Inflorescence axillary whorls of from 

 ten to twenty flowers, sessile. Calyx tubular, the throat dilated, 

 ribbed, the tube straight, or slightly curved, teeth five, awl-shaped, as 

 long as the tube, mostly ciliated. Corolla large, downy externally, 

 white, pink, or purple, in y. the lower lip is beautifully spotted with 

 dark purple dots, the tube long, curved upwards, contracted, and with 

 a hairy ling in the lower part dilated and gaping above, the upper lip 

 elongated, curved, concave, and slightly notched, the lower with the 

 lateral lobes terminating in awl-shaped teeth, reflexed, the middle one 

 reflexed, cordate. Stamens inserted into the mouth of the corolla, 

 curved beneath the upper lip. Anthers oblong, two celled, hairy, of a 

 black purplish colour. 



Habitat. Hedges, borders of fields, and waste places ; common. 

 P. naturalized near Bristol, about London, and Fifeshire, in Scotland, 

 y. Fifeshire, Scotland. Dr. Deiuar. Meadows near Nottingham. 

 Dr. Howitt. 



Perennial ; flowering during the summer months. 



It is not without considerable reluctance that we unite the above 

 under one species ; but after a most careful examination of both our 

 native and foreign species, (for the y. maculatum and . Icevigalum are 

 the most frequent in Italy), we cannot find any permanent character by 

 which to distinguish them. The leaves of these, as well as those of the 

 whole genus, have a disagreeable smell, and are refused by all cattle 

 as food. The flowers are a favourite resort of bees, butterflies, &c., 

 from the sweet fluid which is secreted in the bottom of the tube. 



** Tube of the corolla straight. 



2. L. purpu'reum. Linn. (Fig. 935.) Red Dead-nettle. Leaves ovate, 

 heart-shaped, obtuse, unequally crenated, petiolated, distant below, 

 crowded above, and longer than the whorls of flowers; calyx with 

 lanceolate awl-shaped teeth, spreading after flowering, tube of the 

 corolla straight, with a hairy ring inside, the lateral lobes of the lower 

 lip with two teeth on each side, the upper one subulate.
