M>4 f HE LABIATE FAMILY. (MetUtfr. 



spreading, and 3-lobed. Stamens 4, in pairs, projecting slightly from 

 the tube. M. grandiflora t Sm. 



In woods and shady places, in temperate and southern Europe and 

 western Asia, not extending- into northern Germany. In Britain, con- 

 fined to a few localities in southern and south-western England. FL 

 tummer. 



XI. MAREUBIUM. 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 Labiates by the included stamens, 

 and in that respect allied to the extensive south European genus 

 Sideritis t which, however, has different anthers. 



1. M. vulgare, Linn. (fig. 799). White H. Stem rather thick, a 

 foot and a half high, with spreading branches, thickly covered with a 

 white cottony wool. Leaves stalked, orbicular, 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 naturalised in several parts of America and other countries. 

 Not a common 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

 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, the lateral lobes often reflexed. Stamens 4, 

 in pairs under the upper lip. Nuts smooth, rounded at the top. 



A numerous genus, spread over nearly the whole world, but within 

 the tropics limited to mountain districts. 



Erect perennials, 1 to 3 feet high. 



Plant thickly covered with a white silky wooL Flowers nume- 

 rous, in crowded whorls .... . . . 2. S. germanic* 



Plant green, more or less hairy, 

 ^lowers many in each whorl, forming a close, oblong, terminal 



spike. Leaves mostly radical L S. Betonica. 



I'lowers 6 to 10 in each whorl, forming a long, looae, terminal
