Apparently a biennial plant. Ste7n a foot or more in height, erect, simple, 
square, with the angles margined, glabrous. Leaves rather distantly 
placed in opposite pairs, lanceolate, coarsely serrated, dotted and paler 
beneath, the lower ones subpetiolate, the upper ones sessile. 
Flowers in terminal heads, and bracteated. Bracteas ovate, acuminated, en- 
tire, slightly hairy, purple in the middle. Calyx linear-oblong, tubular, 
swelling in the middle, pubescent, marked with elevated striae, 5-toothed, 
teeth spreading. Corolla an inch and a half long, slender, pubescent. 
Tube and upper lip pure white, lower lip subtrilobed, waved and twisted, 
white, spotted with reddish-purple blotches. Stamens two, united laterally 
by the 1 -celled anthers. Filament much incurved, white, spreading above 
where it supports the anthers. Anthers standing close together, deep 
purple-brown, 1 -celled, and when burst so covered on their surface with 
pollen as to appear but one anther. Germen 4-lobed, placed on a large 
cup-shaped gland. Style very long. Stigma bifid. 
Of this pretty and very distinct species of Monarda, seeds

discoverer, found it in the valley of the Arkansa ; and in the 
account which he has published of his travels, he thus feelingly 
describes the circumstance of his naming this plant in honour 
of his amiable companion. " It is with a satisfaction clouded 
with melancholy, that I now call to mind the agreeable hours 
that I spent at this station (Belle Point), while accompanied
