This plant which was discovered also by Mr. Lyon along the base of 
the mountains of Carolina., but principally in Burke county N. C. I have 
always supposed to be the C. Latifolia of Muhlenberg’s Catalogue. Plant 
generally about 2 feet, obtusely angled, very glabrous. Leaves opposite, 
on petioles nearly an inch long, tapering and somewhat acuminate at base, 
in my specimens not even obtuse much less cordate, about 4 long by 2 
wide. Flowers as usual in a dense terminal spike. Segments of the ca- 
lyx oblong and their margins with those of the bracteal leaves pubescent 
or rather finely fringed. Corolla rose coloured, rather smaller than those 
of the first species. 
Flowers August.
