regularly 4-parted, in others nearly always 5-par ted. The calyx 
is constantly monosepalous, deeply and somewhat irregularly 4- 
to 5-parted, and persistent. 
The corolla is cylindric, urceolate, or campanulate, with the 
limb erect, spreading or reflexed, and together with the stamina 
either persistent at the base of the capsule, or more frequently 
separated from its insertion an^covering its summit. Its texture 
is in some species nearly membranaceous, in others thicker and 
more fleshy. 
The stamina are united with the tube of the corolla up to the 
base of the segments. Near their base, within the tube of the 
corolla, they bear a scale, which is evidently not a distinct organ, 
but only an appendage of the stamina. They are present in all 
the species which I have examined ; sometimes consisting only 
of one or few teeth on both sides of the filament, (as in C. Co- 
fryli,) but commonly forming a distinct lamina. In some they 
are bifid, in others undivided; but in all either crenulate or fim¬ 
briate, or laciniately or pinnatifidly divided. They are erect and 
appressed to the tube in several species; while in others they are 
convergent, closing the tube and including the ovary. 
The ovary is always 2-celled, 4-ovulate ; fjhe styles two, (in a 
single species united into one,) frequently unequal in length ; in a. 
few cases supported by a stylopodium. The stigma is either*fili- 
fqrm, as in the European, or capitate, as in the American Species. 
The capsule is globose or depressed, crowned by the; persistent 
styles and stylopodium (when the latter is present); it is 2-celled, 
and'sometimes 4-seeded ; but more generally by abortion, 3-, 2-, 
and even 1-seeded. In the European species, it separates by cir- 
cumscision from its base, leaving the dissepiment persistent on the 
calyx. In the American, the capsule does not appear to open , 
regularly, but it separates easily from the calyx when ripe. 
I have seen very few abnormal irregularities in the flowers of ^ 
Cuscuta. Sometimes one or more segments of the corolla are 
partially or entirely changed into a stamen, add the capsule is 
occasionally 3-4-carpellary, instead of 2-carpellary.
