Curolla half as loiij; a^jain as the calyx-teeth ; lower lij) notched ; the 

 luaririns at len^'th reflexed. 



In cultivated fields and open jjlaces; in woods and in hedge-banks, 

 and waste gi"ound. Connnon, and generally distributed. 



I'ngland, Scotland, Ireland. Annual. Late Summer, Autumn. 



Stem 1 to 3 feet high, generally much branched; usually more so 

 than in G. versicolor, to which it bears a very close resemblance in 

 habit, but the caly.x-teeth arc generally longer and narrower; the tube 

 more ha':r\'; the corolla smaller, dull rose colour or white, with the 

 lower li]> often spotted with purple. The nucules are very similar, but 

 loss convex on the inner face, and with the two basal lovea; much less 

 olnnous ; they are certainly never green Avlien fully ri|)e in the plant 

 as found about London, being exactly the same olive-brown tint as in 

 G. versicolor. Plant usually of a daiker green than G. versicolor. 



The var. bifida seems to have but slender claims to be considered 

 distinct, though it is a smaller jilant than var. a in all res|)ects. In 

 var. a the corolla is f to | inch long, in var. ^ not more than I inch 

 or % inch. 



Common Ilemp-nettle.

Dr. Prior tells us ttat this plant would be moi-e properly called Hemp Dead 

 Nettle, from its flowers resembling those of the dead nettles, and its leaves those of 

 Heuip.

 biate; tube rather short; upper lip erect, concave, entire, usually 

 longer than the lower; loAver lip spreading, 3-lobed; the middle lobe 

 broader, notched. Stamens 4 ; filaments subparallel under the 

 upper lip of the corolla; anthers approximating in pairs ; anther-cells
