 from May lo September, and is a herbaceous 

 annual. 



Lamiiim hybrijum,\'\\\. ( = L. incisum, Willd. = 

 Z.. disseclum. With.). — The habitat of this species is 

 cultivated und waste ground. This plant has been 

 considered a sub-species of Z. purpureum, from 

 which it differs in the more deeply scalloped leaves, 

 and bracts wedge-shaped below, and erect calyx- 

 teeth, shorter corolla-tube with a scarcely percep- 

 tible ring of hairs. The leaves are stalked, heart- 

 shaped, cut to toothed, the upper broadly ovate, 

 crowded, the upper wedge-shaped below. The 

 flowers are reddish, the whorls touching. The 

 calyx-teeth are .is long as, or longer than the tube, 

 spreading. The corolla-tube is straight, naked 

 within, equal, cylindrical, with a faint ring of hairs. 

 The nutlets are smooth. The plant is 4-18 in. 

 high, flowering from April to October, and is a 

 herbaceous annual. 



Henbit Dead-nettle (Lamium ampUxicaule, L.). 

 — The habitat of this plant is waste sandy places. 

 It is a weed of cultivated and waste ground. 

 Dry places, sandy and chalky fields are also the 

 habitat of this species. The habit is erect. The 

 stems are branched from the base. The pl.ant is 

 hairy or smooth. The leaves are small, stalked, 

 rounded, cut, scalloped, in distant whorls, the 

 lower ones long-stalked, lobcd, the base rounded 

 or heart-shaped, wrinkled, the upper stalkless, 

 clasping (hence amplexicaule). The flowers are 

 purplish-red, the lower in distant whorls. The 

 bracts are stalkless, broader than long, the bases 

 overlapping. The calyx-teeth meet in fruit, and 

 are as long as the tube, or longer, green. The 

 corolla is long, slender, sometimes imperfect, 

 straight, downy, very slender, with no hairs within. 

 The nutlets are small, smooth, three times as long 

 as broad. The plant is 4-12 in. high, flowering 

 from May to August, and is a herbaceous annual. 



Variegated Dead-nettle (Lamium maculalum, 

 h, = L. Icevigatum, Sm.). — This species is found in 

 waste places near gardens, in which it is much 

 cultivated. The plant is allied to L. album, but 

 differs in the calyx and corolla, and has fewer 

 nirely white flowers. The stem is hairy or smooth. 

 The lea%-es are heart-shaped to ovate, narrow- 

 pointed, deeply toothed, scalloped, all stalked, 

 marked with white or green, triangular to heart- 

 shaped, wrinkled, hairy or downy. The flowers 

 are purple, with transverse hairs in the curved 

 equal corolla-tube, narrowed below, enlarged in 

 the throat. The calyx-teeth are broad, bent-back 

 as long as the tube, which is oblique, or longer. 

 The corolla exceeds the calyx. The anthers are 

 hairy. The plant is 6-18 in. high, flowering from 

 May to September, and is a herbaceous peren- 

 nial. 



Ballota ruderalis., Sm. — The habitat of this 

 species is waste places. The plant has an agree- 

 .'ible scent. The calyx -teeth are lance - shaped, 

 gradually acuminate, erect. The plant is softly 

 hairy. In other respects it resembles the last. It 

 is 2-3 ft. high, flow-ering in July and .August, and 

 is a herbaceous perennial.

 long, ascending. The scape is as long as the 

 leaves, short, not furrowed. The flowers are in 

 a slender, long spike, longer than the scape, which 

 is round, with ovate bracts, keeled, as long as the 

 calyx. The sep-ils are free, and have a blunt, 

 well-marked dorsal rib, and have membranous 

 borders. The corolla-tube is smooth. The anthers 

 are purple, on short stalks. The capsule is 2- 

 celled, with 8- 16 seeds. The seeds are flat in
