English Botany, t. 770. English Flora, vol. iii. p. 93. Hooker, 

 British Flora, ed. 4. vol. i. p. 232. Lindley, Synopsis, p. 204. 



Root of long branched fibres. Stem much branched, angular, nearly 

 smooth, mostly of a pinkish hue, procumbent at the base, becoming 

 erect. Leaves roundish, kidney-shaped, hairy, dark green, paler be- 

 neath, the margin deeply crenated or lobed and crenated, the lower 

 ones with rather broad petioles, of greater or less length, mostly smaller 

 than the upper ones, which are sessile, and embracing the stem. In- 

 florescence sessile axillary whorls, of numerous flowers. Calyx tubular, 

 very hairy, ribbed, the teeth lanceolate, awl-shaped, about as long as 

 the tube, very hairy, and closing over the mouth when in seed- 

 Corolla with a long slender naked tube, straight, the upper lip of a 

 fine deep rose colour, concave, downy, the lower paler, and mostly 

 spotted, the lateral lobes without or with very small obtuse teeth. 

 Stamens beneath the upper lip. Anthers hairy. Seeds triangular, 

 oblong, smooth, pale brown. 



Habitat. Waste places, and cultivated fields and gardens, though 

 not very common. 



Annual; flowering from March to June. 



The size of the plant is variable, as well as the pubescence, but it is 

 constant in its characters. The early flowers hare an abortive corolla, 

 but are otherwise perfect. 



5. L. inci'sum, Willd. (Fig. 937.) Cut-leaved Dead-nettle. Leaves 

 ovate, heart-shaped, petiolated, the upper ones broadly wedge-shaped, 

 with short dilated petioles, all irregularly cut and crenated ; teeth of 

 the calyx awl-shaped ; corolla tube straight, naked within ; teeth of 

 the lateral lobes of the lower lip unequal, the upper one awl-shaped.

Root of long branched fibres. Stem erect, or ascending, simple or 

 branched below, angular, nearly smooth. Leaves broadly ovate, heart- 

 shaped, the lower ones small, with long petioles, the middle of the stem 

 naked, and the upper leaves crowded at the top with short dilated foot- 

 stalks, more or less hairy. Inflorescence terminal axillary whorls of 

 sessile flowers. Calyx tubular, slightly ribbed, the teeth equal lanceo- 

 late, awl-shaped, as long as the tube, hairy, and ciliated. Corolla with 

 a long narrow tube, straight, hairy externally, naked within, the upper 

 lip straight, concave, rounded, or emarginate, the lateral lobes of the 

 lower lip mostly with two small teeth, the upper ones awl-shaped, the 

 middle lobe heart-shaped. Seeds triangular, oblong, tapering towards 

 the base, smooth, pale brown.
