the obtuse segments of the calyx ; stamens as long as the limb ; 
the scales pinnatifid-laciniate, convergent, covering the ovary; 
styles as long as the ovate-globose ovary with the stylopodium ; 
remains of the corolla persistent at the base of the subglobose 
capsule. 
Margin of lakes and swamps, in the « American Bottom” op¬ 
posite St. Louis, on Saururus, where it was discovered in Sep¬ 
tember, 1841, by my friend, Ch. Geyer, the indefatigable botanist 
who has signalized hims elf in the North Western Expedition of 
Mr. J. N. Nicollet in 183^Alabama, Dr. A. Prout. Texas, on 
Boehmeria, Polygonum, esc., F. LindhdmerSfA. variety with 
rather larger calyx-lobes, in other respects perf^ly agreeing with 
the above description, was obtained by Dr. A. Gray, in Western 
New York, (also on Saururus ?) 
This species bears a great resemblance to C. Polygonorum; 
but differs from it in the much stouter stems, the greater size of 
the flowers, the larger convergent scales, and the stylopodium on 
the ovary. The stems are one third of a line or more in diame¬ 
ter, and are stouter than in any other of our species. It is the 
latest species in blossom, the flowers not appearing before the 
beginning or middle of September; while C. Polygonorum com¬ 
mences in August, and 0. Cephalanthi and 0. Coryli, which are 
the earliest flowering species of our neighborhood, are in bloom 
,;^Hhe end of July.

Stem branched; flowers pedunculate, Subumbellate, small, 
? 5-parted ; tube of the corolla open campanulate, shorter than the 
long acuminate lobes' and the smooth, roundish, obtuse lobes of 
the-5-angled calyx: stamens shorter than the limb; the scales 
ovate; iSmbri^te, convergent; styles filiform, about equal to the 
globose ovary; capsule-. 
On Euphorbia or Tragia, Norfolk, Virginia, Mr. Rugel; com¬ 
municated by Dr. Gray. Also near Houston, Texas, on different 
low herbs in a wet prairie ; flowering in April, F. Lindheimer. 
Beardstown, Illinois, in sandy soil, Ch. Geyer. 
This species bears some resemblance to the C. Polygonorum, 
to which it is related by the campanulate flower and the acute 
lobes of the corolla ; but is easily distinguished by the small size 
of the flo wers, the 5-angled calyx, whose lobes are not triangular,
