Root creeping, perennial. Stem about 2 feet high, 4 angled, ficquentlv 

 branching. The lower leuiws attenuated at base into a short petiole, ob- 

 tuse, tlie upper ones narrow, almost linear. Plotoers in vigorous plants 

 paniculate. The panicles composed of simple opposite branching racemes. 

 i- /mt-ers opposite. Bractea a leaf at the base of each peduncle, lanceo- 

 late, entire, longer than the peduncle and calyx. Cfl(j/a: bilabiate, lips 

 nearly equal, entii e, tne upper one furnished with a transverse appendage 

 hke a crest on its back. Corolla 2-lipped, villous, pale blue, spotted in 

 the throat with white, tlie upper lip 3-cleft, the lateral segments small, 

 slightly reflexed, the intermediate compressed, vaulted, emarginatc, the 

 lower lip shorter, 2 cleft, obtuse. Stamens shorter than the corolla. 

 Jiitliers hairy. Style about as long as the stamens. Stigmas 2, acute. 

 -Seerf globose dotted, 1, 2, or 3, frequently abortive. 



_ This plant when young has frequently all of its leaves entire, in this state 

 It IS said to be the S. Hyssopifolia of Linna?us, it varies however so much not 

 only in the leaf but in the size of the flower, as to make it doubtful wheth- 

 er two species are not yet included under this name. The name itself 

 ought to be changed, Integrifolia Is surely missapplied when given to a 

 plant of which every mature leaf has its margin indented. 



Grows in ditches and damp lands, very common along the sides of 



roads. 



May — August.
