Stem 2 — 3 feet high, pubescent. Leaves strictly cordate, acute, but not 
at all acuminate, somewhat rugose, pubescent or rather hairy on both sur- 
faces, on petioles 1—3 inches long. j Bracteas longer than the pe- 
duncle and calyx, abruptly attenuated at base, the lower ones acuminate, 
the upper simply acute. Calyx villous, tinged with pOfple. The upper 
lip of the corolla , bright bluish purple, the lower lip paler, almost' white. 
I have described this species from excellent specimens sent me by my 
friend Mr. Collins of Philadelphia.

Stem about 2 feet high, square, glabrous, except at the angles, not fur- 
rowed as in all of the preceding species. Leaves ovate, very obtuse at 
base, acuminate, with the serratures very acute, the lower ones on mode- 
rately long petioles, the upper sessile. Branches very numerous, all termina- 
ting in leafy racemes and bearing also axillary racemes. Calyx nearly 
glabrous, smooth, the operculum or crest somewhat conical. Flowers ve- 
ry small, blue. 
This is the species which has laterly acquired so much celebrity in the 
cure of Hydrophobia, but whose virtues I fear are more than doubtful. 
Grows in the upper and mountainous districts ©f Carolina and Georgia. 
Flowers June-— September.
