G. bifida, Bonn. Koch, Sjn. Fl. Germ, et Helv. ed. ii. p. 651. licicJi.fd. 1. c. p. 18. 



Corolla half as long again as the calyx-teeth ; lower lip notched ; the 

 margins at length reflexed. 



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

 and waste ground. Common, and generally distributed. 



England, 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 calyx-teeth are generally longer and narrower; the tube 

 more hairy; the corolla smaller, dull rose colour or white, with the 

 lower lip often spotted with purple. The nucules are very similar, but 

 less convex on the inner face, and with the two basal foveas much less 

 ob\aous ; they are certainly never gi-een when fully ripe in the plant 

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

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



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

 distinct, though it is a smaller plant than var. a in all respects. In 

 var. a the corolla is f to |- inch long, in var. 3 not more than ^ inch

Common Hemp-nettle. 



French, Galeope fetrahite. German, Gemeiner Daiin. 



Dr. Prior tells us tliat tliis plant TTOuld be more properly called Hemp Dead 

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

 Hemp.

 at length spreading, of 5 subspinous-pointed teeth. CoroUa bila- 

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

 longer than the lower; lower 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 

 joined at the apex, and divergent nearly in a straight line, opening 

 by a longitudinal slit common to both. Nucules truncate at the
