bluish-purple, in whorls of 6 or 8, forming shorter andmore crowded spikes 

 than in the wood S.; the calyx-teeth long and pointed, but not prickly. 

 CoroUa-tube rather shorter, with a broader and somewhat shorter lower lip 

 than in the ivood S. 



In ditches, and on moist banks, in Europe, Russian Asia, and northern 

 America, generally a more northern plant than the ivood S. ' Abundant in 

 Uritain. Fl. summer and autumn. A variety with rather broader and 

 longer-stalked leaves, and a rather longer tube to the coroJla, has been 

 distinguished imder the name of S. ambiffua (Eiig. Bot. t. 2089), but it 

 appears to be connected with the common form by too close a chain of 

 intermediates to be separable from it. 



5. Field Stacliys. Stachys arvensis, Linn. 

 (Eng. Bot. t. 1154.) 



A slender, hairy annual, very different in aspect from the preceding spe- 

 cies; the stems branched, decumbent or shghtly ascending, from an inch or 

 two to nearly a foot long. Leaves small, ovate, scarcely cordate. Flowers 

 small, of a pale purple, in whorls of 2 to 6 or 8, forming loose, leafy spikes. 

 Calyx-teeth as long as its tube. Corolla scarcely longer than the calyx. 



In fields and waste places, spread over Europe and Russian Asia, except 

 the extreme north, and carried out with our crops even to tropical countries. 

 Common in England, but appears only occasionally in Ireland and Scotland. 

 Fl. the tvhole season. 



XIII. GAIiBOFSZS. GALEOPSIS. 



Erect or slightly decumbent annuals, with spreading branches, and flowers 

 in dense whorls in the upper axils or at the summit of the branches. Calyx 

 neai'ly regular, with 5 pointed teeth. Corolla with a tube longer than the 

 calyx ; the upper lip erect, concave and entire or slightly notched; the lower 

 spreading and 3-lobed. Stamens 4, in pairs ; the cells of the anthers opening 

 by a transverse slit, bordered with hairs. 



A small genus, consisting of European and north Asiatic weeds of culti- 

 vation, distinguished from Stachys chiefly by the anthers. 



Hairs of thp plant short and soft. Calyx-teeth not longer than the tube. 

 Stem not swollen under the nodes. 



Flowers purple 1. Sed G. 



Flowers yellow 2. Doivny G. 



Hairs of the plant long and stiff. Calyx-teeth long and almost prickly.

1. Red Galeopsis. Galeopsis Iiadanum, Linn. 



(Eng. Bot. t. 884.) 



An annual, seldom above 8 or 9 inches high, with very spreading, almost 

 decumbent branches, and covered with a very short, soft down. Leaves 

 shortly stalked, narrow-ovate or lanceolate, coarsely toothed. Flowers 

 purple, 6 to 10 together, in dense whorls in the upper axils, the upper ones 

 forming a terminal head. Calyx-teeth usually very pointed, but shorter 

 and less prickly than in the common G.; the tube of the coroUa considerably 

 longer than the calyx. 



In cultivated and waste places, all over Europe and Russian and western 

 Asia. Frequent in southern England, decreasing northward and eastward, 

 but occurs also in Ireland. Fl. stimmer and autumn. It varies much in
