B. glabrior ; cymes more or less glabrous, cal. lobes broader. 
somewhat obtuse, nearly as long as the tube of the cor. — 
Texas: both vars. together in dry sterile prairies, parasiti- 
cal (a.) on Euthamia, Aster, &c.; and f. on Petalostemon 
(Drummond 3d coll. No. 247.) 
The lowest of all the American species and (with C. penta- 
gona) the smallest-flowered; not particular as to the plants 
on which it grows, but creeping over all indiscriminately. 
This is the only Cuscuta I have ever seen with any approach 
to pubescence. Allied to C. Polygonorum; but distinct by 
the lax and few-flowered cyme, &c. 
7. C. Polygonorum (n. sp.); stem low branching, flowers 
subsessile glomerate mostly 4-partite, tube of the cor. cam- 
panulate nearly equalling the acute campanulate or spreading 
lobes and the acute calycine segments, stamens as long as 
the limb, scales mostly bifid laciniate appressed, styles i 
long as the depressed ovary, remains of the cor. persistent at 
the base of the depressed capsule. (Tas. III. f. 7.) 
On different Polygona, also on Lycopus, Penthorium, ar

Of much humbler growth than C. Saururi, &c. with orange- _ 
coloured stems, growing in overflowed places, and the mar 
gins of ponds, W. of St. Louis.* |
