1. Henbit Lamium. Lamium amplexicaule, Linn. 

 (Fig. 803.) 

 (Eng. Bot. t. 770. Henbit.) 

 A low, decumbent, much branched 

 annual, a few inches, or, when very 

 luxuriant, near a foot long. Lower leaves 

 small, orbicular, on long stalks; the floral 

 ones closely sessile, broadly orbicular, 

 and deeply crenate or cut. The flowers 

 form 1, 2, or 3 compact whorls. Calyx 

 softly hairy, with short teeth. Corolla 

 about half an inch long, of a purplish- 

 red, with a slender tube ; the lateral 

 teeth of the lower lip scarcely perceptible. 

 In cultivated and waste places, through- 

 out Europe and central and Russian 

 Asia, except the extreme north. Ex- 

 tending all over Britain. FL the whole 

 season. A variety with rather longer teeth 

 to the calyx, and more distinct lateral 

 teeth to the lower lip of the corolla, is 

 occasionally found mixed with the common one, especially in the more 

 northern localities, and has been distinguished as a species, under the 

 name of L. intermedium (Eng. Bot. Suppl. t. 2914).

2. Red Lamium. Lamium purpureum, Linn. (Fig. 



(Eng. Bot. t. 769. 

 A spreading annual, like the henbit L., 

 and the lower leaves are likewise small 

 and orbicular, on long stalks ; but the 

 upper leaves, even the floral ones, are all 

 shortly stalked, and ovate, heart-shaped, 

 or triangular, often pointed, and, in the 

 common variety, less deeply toothed. 

 Calyx-teeth fine, and spreading. Corolla 

 of a purplish-red, shorter than in the 

 henbit X., with a broader, more open 

 tube, and a more hairy upper lip; the 

 lower lip with a short, fine tooth on each 

 side. 



In cultivated and waste places, through- 

 out Europe and western Asia, except 

 the extreme north. In Britain, more 

 common than the henbit L., especially as 



ien weed. Fl. the whole season. Fig. 804.
