3. Common Galeopsis. Galeopsis Tetrahit, Linn. 



(Tig. 800.) 



(Eng. Bot. t. 207. Hemp-Nettle.) 



A coarse annual, 1 to 2 feet high or 

 even more, although sometimes very 

 dwarf, with a few spreading branches, 

 green, with stiff, spreading hairs, and 

 the stems swollen under the nodes. 

 Leaves stalked, ovate, very pointed, and 

 coarsely toothed. Flowers numerous, 

 in close whorls in the axils of the upper 

 leaves. Calyx-teeth long and almost 

 prickly. Corolla, in the common variety, 

 pale-purplish or white, exceedingly va- 

 riable in size, sometimes not longer than 

 the calycine teeth, moref requently twice 

 that length, and sometimes much longer. 

 In cultivated and waste places, and 

 occasionally also in woods, extending all 

 over Europe and Russian Asia. Fre- 

 quent in Britain. FU summer and au- 

 Fig. 800. tumn. The variegated 6r. (G. versicolor, 



Eng. Bot. t. 667) is a marked variety, 

 often considered as a distinct species. It is usually a larger plant, and 

 the flowers are also larger, and yellow, with a purple spot on the lower 

 lip ; but in this, as in the purple variety, the size of the flower is very 

 variable, and in some localities the two pass gradually one into the other. 



XIV. BALLOTA. BALLOTA. 



This genus, closely allied to the shorter-flowered Stachyses, differs 

 chiefly in the the calyx, which is enlarged at the top, so as to be nearly 

 funnel-shaped, and, in several exotic species, has 10 or even more teeth. 

 The corolla, stamens, and nuts are nearly as in Stachys. 



The exotic species belong almost exclusively to the Mediterranean 

 region, and western Asia.
