longer than the flowers, in loose, few-flowered, cymose clusters; calyx 
shorter than, or about equaling, the corolla tube; lobes ovate to triangular- 
ovate, obtuse or slightly acutish, slightly, if at all, overlapping; corolla 
widely campanulate, lobes longer than the tube, spreading or upright with 
indexed tips, ovate or lanceolate, obtuse to acute; stamens shorter than the 
lobes or rarely longer than the lobes; oval anthers about equal to, or shorter 
than, the slender filaments; scales reaching the stamens, ovate, fimbriate, 
bridged below the middle; styles about equal to the globose ovary; capsules 
depressed-globose, much larger than the flower, exserted, withered corolla 
persistent at the base, intrastylar aperture large, not circumscissile; seeds 
1-1.25 mm. long, globose, hilum oblong, perpendicular. 
This is the smallest of the species seen from South America and seems 
to produce capsules sparingly. Only two or three mature fruits were seen 
in the several specimens examined.

Cuscuta cristata Engelmann, Trans. Acad. Sci. St. Louis 1: 507. 1859. 
Stems medium. Flowers 2.5-3 rnm. long, slightly fleshy and glandular, 
subsessile on short, stout pedicels in few- to many-flowered, lateral, cymose 
clusters, perianth segments frequently uneven; calyx as long as the corolla 
tube; lobes broadly ovate, obtuse, frequently with an uneven, cristate 
carina which may extend down on to the pedicel, overlapping; corolla 
widely campanulate, early becoming somewhat globular about the devel¬ 
oping capsule; lobes slightly shorter than the tube, ovate, obtuse, spreading, 
becoming reflexed in fruit; stamens shorter than the lobes, the oval anthers
