356 THE LABIATE FAMILY. [Stachys. 
narrower ; they are very shortly stalked, oblong or lanceolate, slightly 
cordate at the base, 2 to 4 inches long. Flowers of a pale bluish-purple, 
in whorls of 6 or 8, forming shorter and more crowded spikes than in 
S. sylvatica ; the calyx-teeth long and pointed, but not prickly. Corolla- 
tube rather shorter, with a broader and somewhat shorter lower lip than 
in S. sylvatica. 
In ditches, and on moist banks, in Europe, Russian Asia, and northern 
America, generally a more northern plant than S. sylvatica. Abundant 
in Britain. Fl, summer and autumn. 8S. ambigqua, Sm., is a hybrid with 
S. sylvatica ; it has rather broader and longer-stalked leaves, and a 
rather longer tube to the corolla. 7 
5. S. arvensis, Linn. (fig. 804). Field S.—A slender, hairy annual, 
very different in aspect from the preceding species ; the stems branched, 
decumbent, or slightly 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 tro- 
pical countries. Common in England, rare in Ireland and Scotland. 
Fl. the whole season. : 
XIII. GALEOPSIS. 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 nearly 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 
cultivation, distinguished from Stachys chiefly by the anthers. 
Hairs of the plant short and soft. Calyx-teeth not longer than 
the tube. Stems not swollen under the nodes.

1.G. Ladanum, Linn. (fig. 805). Red ee 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 G. Tetrahit, the tube of the corolla 
considerably longer than the calyx. 
In cultivated and waste places, all over Europe and Russian and 
western Asia. Frequent in southern England, decreasing in Scotland, — 
local in east Ireland. Fl. summer and autumn. It varies much in the — 
breadth of the leaf, from ovate to nearly linear; in the degree of 
hairiness, and in the size of the flower. [G. angustifolia, Ehr., is a
