Anon. Caroliniensis. Walt. 
Stem 1 8 — 20 inches high, 4-angled, and with the whole plant hairy. 
Leaves ovate and oval, lanceolate, entire, attenuated at base into a petiole 
half an inch long. Flowers axillary, generally 3 in each axil. The larg- 
er Braeteal leaves as long as the calyx, the lesser about half as long. 
Calyx 5-parted, linear lanceolate, the upper half almost setaceous, very 
hispid. Corolla pale blue, the tube longer than the calyx, the border 
somewhat campanulate, 5-parted, with the segments rounded, nearly 
equal. Stamens shorter than the corolla. Style longer than the stamens, 
slightly 2-cleft at the summit. Stigmas equal. Seeds few, (4, Walter.) 
in each ceil of the elastic capsule, 
I know not how Pursh could have called the segments of the calyx 
lanceolate, they are very accurately represented by Dill. Hort. Eltli. T, 
249* F. 321. excepting that in number 5 and 6 the setaceous points are not 
sufficiently extended, but in number 1 from which he derived the epithet 
Comosa, the representation is very accurate. 
Grows generally in damp soils, may be found in great luxuriance in the 
high ridges in river swamps. 
Flowers through the whole Summer, beginning in May.

E. 
Hirsute, branching; 
leaves oval lanceolate, 
nearly acute, sessile, 
segments of the calyx 
subulate, hispid, a lit- 
tle longer than the 
tube of the corolla. 
Stem erect, 12 to 18 inches high, very obtusely 4-angled, sparingly 
branched, very hirsute. Leaves opposite, acute at each end, slightly un- 
dulate, almost hispid. Flowers generally one in each axil. Segments of 
the Calyx regularly subulate, rather longer than the tube of the corolla. 
Corolla pale blue. Style very long. Every part of the plant much 
smaller than in the preceding specieg.
