354 THE LABIATE FAMILY. [ Melittis. 
X. MELITTIS. MELITTIS. 
A genus limited to a single species, differing from the long-flowered 
species of Stachys chiefly by its large calyx, usually 3-lobed, and by its 
axillary flowers. 
1, M. Melissophyllum, Linn. (fig. 796). Balm Melittis.—An erect 
and slightly hairy perennial; the stems nearly simple, 1 to 1} feet high. 
Leaves stalked, heart-shaped, and coarsely toothed, about 2 inches long. 
Flowers pink, or variegated with white and purple, in axillary whorls of 
2 to 6, shorter than the leaves. Calyx of a thin texture, broadly cam- 
panulate, with 3 broad, rounded lobes, of which the upper one is sometimes 
2- or 3-toothed. Corolla with a broad tube, near an inch long; the upper 
lip thrown back and slightly concave ; the lower lip large, spreading, and 
3-lobed. Stamens 4, in pairs, projecting slightly from the tube. M. grandi 
flora, Sm. | 
In woods and shady places, in temperate and southern Europe and 
western Asia, not extending into northern Germany. In Britain, confined 
to a few localities in southern and south-western England. 7. summer, 
XI. MARRUBIUM. HOREHOUND. 
Perennial herbs, usually cottony or woolly, with much wrinkled leaves 
and rather small flowers in axillary whorls or clusters. Calyx with 5 or 
10 ribs, and as many equal pointed teeth. Corolla with a short tube; the 
upper lip erect, usually notched; the lower lip spreading and 3-lobed. 
Stamens 4, included within the tube of the corolla, all the anthers 2-celled. 
Nuts rounded at the top. 
A rather numerous genus in southern Europe and Western Asia, readily 
distinguished amongst British Labiate by the included stamens, and in that 
respect allied to the extensive south European genus Sideritis, which how- 
ever has different anthers, 
1, M. vulgare, Linn. (fig. 797). Common Horehound, White Hore- 
hound.—Stem rather thick, a foot and a half high, with spreading 
branches, thickly covered with a white cottony wool. Leaves stalked, or- 
bicular, soft, and much wrinkled. Flowers in ‘dense whorls or clusters in 
the axils of the upper leaves, small, of a dirty white. Calyx with 10 small, 
hooked teeth. Upper lip of the corolla narrow, erect, and 2-cleft. 
On roadsides and waste places, in temperate and southern Europe and 
central and Russian Asia, extending northwards into Scandinavia, and now 
naturalized in several parts of America and other countries. Not a com- 
mon plant in England or Ireland, and still more rare in Scotland ; although 
found in abundance at particular localities. [It is a doubtful native, except 
in the Isle of Wight.] Fl. summer and autumn. |

XII. STACHYS. STACHYS. 
Rather coarse, hairy herbs (or, in some exotic species, low shrubs), with 
the leaves often cordate, and flowers, in the British species, in whorls of 6 
or more, forming terminal racemes, spikes, or heads. Calyx 5- or 10-ribbed, 
with 5 nearly equal, erect or spreading, pointed teeth. Corolla with the 
upper lip erect, concave, and entire; the lower lip longer, spreading, 3-lobed,
