Root perennial. Stem 1 to 3 feci high, erect, simple, or sparingly branched, 

 4-angled, smooth, or very minutely pubescent above. Leuves opposite, sessile, l 

 lo 3 or 4 inches long, and 1 fourth to 3 fourths of an inch wide, varying from lin- 

 ear-lanceolate to lance-oblong and obovate-lanceolate, generally acute, denticu- 

 late (or sometimes sharply incised-serrate) above the middle, tapering and entire 

 at base, smooth, and often somewhat pellucid-punctate. Plotters opposite, and 

 distant, in a slender terminal bracteate raceme,— -or sometimes crowded in dense 

 quadrifarious spikes, which arc terminal and subterminal (or axillary opposite 

 and crowded, and thus rendered sub-paniculate at the summit of the stem) ; ra- 

 cemes, or spikes, 2 or 3 to 6 or8 inches in length ; bracts varying from lance-ovate 

 and acuminate to subulate, shorter than the calyx; pedicels short; calyx 3 or 4 

 lines long, minutely pubescent, with 5 nearly equal acute teeth. Corolla palo 

 purple, or flesh-colored, sometimes variegated, half an inch loan Inch long, much 

 dilated above, tapering to the base, finely pubescent externally.

Obs. Collected in Aug. 1836, by -Mr, Joseph Rinehart. The specimens col. 

 lectcd by Mr. Rinehart clearly belong to the Dracocephalum denticulatum, of 

 Authors. Mr. Bentham has reduced all the species, cited above, into owe; and 

 adds, that they are scarcely entitled to be considered as varieties. The old D. 

 virginianum, however, to roy view, presents a strongly marked variety, if nothing 

 more. I have cultivated it for a number of years, and find it very constant in its 

 characters,— especially its dense paniculate, or rather sub-fasciculate, spikes,— 

 and its more coriaceous and sharply incised-serrate leaves. If Mr. Be?Uham bo 

 correct, the above is probably the only species known in the U. States.
