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

 3 terminal whorls which resemble proliferous heads. Oswego Tea.

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

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

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



Rocky banks. N. Y. to Car. 1 July, Aug. 'ZJ-.—S^^eOT 2 feet high, obtuse

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

 rounded at base, with a few coarse teeth, varying in the de^e 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.
