THE LABIATE FAMILY. 



XI. HOREHOUND. MAKRUBIUM. 



Perennial herbs, usually cottony or woolly, with much-wrinkled 

 leaves and rather small flowers in axillary whorls or clusters. Catyx 

 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, which however has different anthers. 



1. 



Common Horehound. Marrubium vulgare, Linn. 

 (Fig. 792.) 



(Eng. Bot. t. 410. White HoreJiound.) 



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 

 naturalized in several parts of America 

 and other countries. Not a common 

 plant in England or Ireland, and still 

 more rare in Scotland, although it may 

 occasionally be found in abundance at 

 particular localities. Fl. summer and 

 autumn. 



XII. STACHYS. STACHYS. 



Bather 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.
