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- 

 Jiorescence 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.
