Stem generally erect, about twelve inches high, obtusely four-angled, car- 
nose, lucid, glabrous, branching sometimes from the base. Leaves oppo- 
site, decussate, lanceolate, acuminate, coarsely serrate, three-nerved, sprinkled 
with hairs on the upper surface, petioles very long, the lower longer than 
the leaves. Flowers in corymbose panicles, much shorter than the petioles, 
sometimes recurved. Sterile and fertile florets sometimes intermingled, 
sometimes one half of the panicle will be exclusively fertile the other sterile. 
Calyx of the sterile flower, fourJeaved, leaves lanceolete. Stamens twice as 
long as the calyx, expanding as in all the species of this genus which I have 
examined, elastically. Of the fertile floret calyx 3? leaved, persistent. 
Style 0. Stigma sessile. Seed compressed, ovate, glabrous. 
I have never been able to discover a nectary in the sterile florets of this 
species. 
Grows in shaded wet soi s. 
Flowers July — September. 
2. Urens. L. 
U. foliis oppositis, el- 
lipticis subquinquener-

Leaves opposite, ellip- 
tic, somewhat 5-nerved, 
acutely serrate; spikes 
by pairs; flowers clus- 
tered.

Stem about twelve to fourteen inches high, obtusely four-angled, hairy, 
somewhat hispid, branching. Leaves opposite, cordate ovate, rugose, hairy, 
coarsely toothed, three-nerved, with the exterior nerves divided, sprinkled 
besides the hairs with white prickles. Petioles nearly an inch long. Flow- 
ers in axillary racemes, two in each axil, shorter than the petiole. Sterile 
and fertile florets intermingled. Of the sterile floret calyx four-leaved, 
leaves hairy, obtuse; filaments longer than the calyx, expanding elastically 
and discharging elastically the pollen; nectarium cyathiform; of the fertile 
floret calyx two-leaved, persistent, seed compressed. 
Grows in damp soils, common around Beaufort; St. Mary’s, Georgia. 
Flowers December to F ebruary.
