424 THE LABIATE EAMILT, 



the breadth of the leaf, from ovate to nearly linear ; in the degree of hairi- 

 ness, and in the size of the flower. 



2. Downy Galeopsis. Galeopsis ochroleuca. Lam. 



(Eng. Bot. t. 2"353.) 



Very much like the red G., but more densely covered with soft, almost 

 sUky hau's, which give the uj)per part a whitish hue, and the flowers are 

 more numerous, considerably larger, often above an inch long, and of a 

 pale yellow colour. 



In cultivated and waste places, in temperate Europe, from Spain to Scan- 

 dinavia, and eastward to south Russia. Very local in Britain, and chiefly, 

 if not exclusively, in the north of England. Fl. mtmrner and autumn. It 

 is very doubtful whether it be more than a variety of the red &., and it is 

 even said that the one has been raised from the seeds of the other. 



3. Common Galeopsis. Galeopsis Tetrahit, Linn. 



(Eng. Bot. 207. Setup- 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 swoUen under tlie 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 variable in size, 

 sometimes not longer than the calycine teeth, more frequently twice that 

 length, and sometimes much longer. 



In cultivated and waste places, and occasionally also in woods, extend- 

 ing all over Europe and Russian Asia. Frequent in Britain. Fl. summer 

 and autmnn. The variegated O. {&. 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 veiy variable, and in some localities the two pass gradually one into the 

 other. 



XIV. BALI. OTA. BALLOTA. 



This genus, closely allied to the shorter-flowered Stachyses, difiers chiefly 

 in 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 re- 

 gion, and western Asia. 



1. Black Ballota. Ballota ni^a, Linn. 

 (Eng. Bot. t. 46. B. fcetida and B. ruderalis, Bab. Man. Black Hore- 



hound.) 

 A coarse, erect, hairy, branching perennial, 2 to 3 feet high, softly hairy 

 all over, with a strong, disagreeable smeU. Leaves stalked, ovate or cordate, 

 coarsely toothed. Flowers in dense axOlary clusters, often slightly stalked, 

 and turned to one side, assuming less the appearance of whorls than in 

 Stachys, usually shorter than the floral leaves, and accompanied by a 

 number of stiff, linear bracts. Calyx 4 or 5 lines long, green or pm-plish,
