A remarkable species. The stems are very much branched, filiform ; inflorescence loose paniculate, pedicels 
h many cuspidate bracts, some of them surrounding the calyx like an involucrum, similar in shape but smaller than 
the sepals ; sepals somewhat lacerate or crenulate, ovate, carinate (the carina less distinct in the var. 8.), cuspidate, 
interior ones rather obtuse, all concave, loosely imbricated. Lobes of corolla thin, membranaceous, with a strong 
middle nerve, formed by large oblong or linear cells ; when dry, convolute ; the exterior ones generally somewhat 
cuspidate, the interior ones obtuse; at the base the leben are dilated and cover one another more sage in any other 
orth American species. Styles remarkably slender and long, about the length of the stamen 
elongated after flowering, when the corolla assumes an Seeiclatn shape, and finally covers like a "va [225 (17)] 
the upper = of the se capsule. — It appears to be an intermediate form between Cuscuta pro 
and Lepidan The var. 8. has larger and thinner flowers, of paler color, and the lobes of the sctella lanceolate 
a acute.
