nearly straight and entire, involving the filaments ; lower re- 

 flexed, broader, 3-lobed, the middle lobe longer. Stamens 2, 

 exserted from the upper lip of the corolla. 



1. M. didyma Linn. : leaves ovate or ovate-lanceolate, acuminate, mostly 

 rounded or somewhat cordate at base, mucronate, serrate, a little hairy, on 

 ciliate petioles ; floral ones and exterior bracts oblong-lanceolate, nearly 

 sessile, colored ; calyx incurved, smooth, naked in the throat ; corolla 

 smoothish. M. 'purpurea Lam. M. coccinea Mich. M. Kalmiana Pursh. 



Moist grounds. Can. to Car. July, Aug. 1\.. Stem 2 3 feet high, acute- 

 angled, simple or branched at the top, somewhat pubescent. Leaves quite vari- 

 able, sometimes tapering at base as in Pursh's figure of M. Kalmiana, but usu- 

 ally rounded or even subcordate. Flowers scarlet or crimson, in 2 very rarely 

 3 terminal whorls which resemble proliferous heads. Oswego Tea. 



2. M. fistulosa Linn. : leaves ovate-lanceolate, rounded and somewhat 

 cordate at base, acuminate, coarsely toothed, thin and nearly smooth, on 

 slightly pubescent petioles ; floral ones and outer bracts slightly colored ; 

 calyx somewhat curved, with the throat bearded ; corolla pubescent. 



Rocky banks. N. Y. to Car. ? July, Aug. ^.Slem 2 feet high, obtuse 



tigled, simple, usually hollow. Leaves yellowish-green and somewhat mem- 



branaceous ; petioles about half an inch long. Flowers pale yellow, in 1 or 2 



whorled heads which are smaller than in the preceding. Abundant near 

 Rochester, N. Y. Pale Monarda. 



3. M. edlophytta Mich. : leaves ovate-lanceolate, remotely toothed, smooth 

 above, somewhat hairy beneath ; floral ones and the outer bracts colored ; 

 calyx short, densely bearded at the throat. M. longifolia Lam. M. ol-

Rocky banks. Can. to Car. W. to Miss. July. %.Stem 34 feet high, 

 obtuse-angled, much branched and hairy above. Leaves tapering or slightly 

 rounded at base, with a few coarse teeth, varying in the degree of pubescence. 

 Flowers pale violet or bluish, in simple heads which are about as large as in the 

 preceding. The habit of this plant is entirely different from that of M. fistulosa ; 

 the stem is taller and constantly much branched, the leaves are thicker and 

 more hairy, and the color of the flowers is uniformly different. It is also, I think, 

 more common. Horse Mint. Wild Bergamot.
