MONOECIA TRIANDRIA. 
Annual. Stem divaricate, somewhat prostrate, angled, glabrous. (Lower 
leaves hastate slightly toothed, Willd.) upper lanceolate, narrow, entire, gla- 
brous, attenuated at base. Flowers in compact clusters axillary and terminal. 
Calyx of the fruit deltoid, hastate, sometimes denticulate, the back strongly 
veined but not crested. 
Found though rarely near the margin of salt water around Charleston, 
perhaps an exotic. I have never seen the lower leaves hastate, but the ear- 
ly leaves of plants frequently decay before the flowers are expanded. 
Flowers June — July. 
| 3. Laciniata. 
Stem erect, herba- 
ceous; leaves triangu- 
lar, deeply toothed, 
whitish underneath; ca- 
lyx of the fruit rhom- 
boidal, three-nerved, 
toothed.
