THE LABIATE FAMILY. 



& ambigua (Eng. 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 Stachys. Stachys arvensis, Linn. (Fig. 797.) 

 (Eng. Bot. t. 1154.) 



A slender, hairy annual, very different 

 in aspect from the preceding species ; 

 the stems branched, decumbent or slight- 

 ly ascending, from an inch or two to 

 nearly a foot long. Leaves small, ovate, 

 scarcely cordate. Elowers 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 whole season.

 with hairs. 



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

 cultivation, distinguished from Stachys chiefly by the anthers.

 the tube. Stem not swollen under the nodes. 



Flowers purple , 1. Red Q.
