Root perennial. Stem herbaceous, 2—4 feet high, very much branched, 4 - 
dngled, glabrous, but sprinkled near the summits of the branches with ca- 
pitate hairs. Leaves opposite, ovate, lanceolate, rugose, a little hairy, the 
lower ones sometimes slightly cordate. Flowers in long compound ter- 
minal panicles, on pubescent peduncles. Calyx somewhat campanulate, 
5-cleft, with the segments equal, erect. Corolla glabrous, greenish, ting- 
ed with purple; the tube globose, twice as long as the calyx, the border 
5-cleft, with segments unequal, the four upper ones erect, the lower small, 
reflexed. A small spathulate purple appendage is attached to the tube of 
the corolla just below the base of the upper segment. Stamens longer 
than the tube of the corolla, the two longer ones appear to be later than 
the other two, in coming to maturity. Filaments hairy, dilated towards 
the summit. Anthers 1 -celled, opening transversely. Style longer than 
the stamens. Stigma obtuse. Capsule ovate, somewhat compressed, 
.opening at the summit. Seeds numerous, a little rough. 
Grows in rich, shaded, loose soils. 
Flowers August — October.
