5-fidis.” Other botanists add, 11 stigmatibus capitatis.” Nuttall, 
gen. (II, addit.) on the other hand has it: “flowers mostly pen- 
tandrous and sessileand Sprengel (Syst. Yeg. I, 864) brings 
his C. Americana under the section with glomerate subsessile 
flowers. While these authors refer to one or more North Ameri¬ 
can species, others apply the name with at least equal justice 
to a West Indian plant. Linnaeus himself cites Sloane, Hist. 
I, t. 128, f. 4, After him Jaquin, (Stirp. Am. p. 24,) Swartz 
(Obs. p. 54) and others describe a West Indian species. The 
name may therefore properly be reserved for Sloane’s plant, or 
may be discarded altogether. The only reason I have in sup¬ 
posing that most North American authors give it to Cuscuta mil- 
givaga , is that this is the most common and the widest spread 
species in the United States, and has generally the flowers longer 
' ;peduncled than any other. 
To This Cuscuta is intermediate between C. Cephalanthi and CU 
Saururi. In all three the lobes of the calyx and corolla are ob¬ 
tuse, and the former shorter than the tube of the corolla. But 
our plant is distinguished from both by the carina of the lobes 
\of the calyx, which is formed by larger uneven prominent cells, 
-and by the large pellucid dots in the substance of the corolla, 
which may be mistaken for glands, but are nothing but cells 
larger than the rest of the tissue. The carinae of the calyx are 
most prominent on the three outer lobes, and sometimes hardly 
perceptible on the two inner; but even then the. large irregular 
cells .are easily distinguished by the lens. The lobes of the corolla 
are-shorter than the tube, as in C. Cephalanthi: the scales are large 
and incurved, and the corolla remains at the base of the capsule, 
as in C. Saururi. The tube is campanulate, but deeper ekft 
than in C. Saururi or C. Polygonorum. The flowers and fruit 
are larger than in C. Cephalanthi, and (especially in var. «.) nearly 
of the same size as in C. Saururi. The styles are in some spe¬ 
cimens a little longer, in others a little shorter than the ovary, 
which appears to-be. crowned by a stylopodium : this however it 
is hardly possible to ascertain satisfactorily in the dried specimens.
