Jan., 1923] YUNCKER — SOUTH AMERICAN SPECIES OF CUSCUTA 
9 
about equal to the stout, subulate filaments; scales reaching the stamens 
or shorter, bridged below the middle, slightly spatulate, sparingly fringed 
with medium-length processes, particularly about the upper half; styles 
stoutish, much shorter than the large, globose ovary which is thickened at 
the top, stigmas very small. Capsule depressed-globose, thin towards the 
base where it may break away when pulled, carrying the withered corolla 
about it or toward the base, styles becoming divaricate, intrastylar aperture 
large and rhomboid; seeds about 1.5 mm. long, oblique, rostrate. 
This species is distinguished mainly by the shape of its capsule and the 
size of the stigmas.

Scales ovate, prominently fringed. 
Calyx lobes ovate, obtuse or acutish, not exceeding the corolla. 
Styles as long as the ovary, not divaricate. 
Flowers 2-3 mm. long, papillose-hispid (no specimens of this have 
been seen from South America). hispidula . 
Flowers usually larger, not papillose-hispid. neuropetala. 
Styles short, becoming divaricate in fruit. subnuda. 
Calyx lobes lanceolate, acute, usually exceeding the corolla. longisepala. 
Scales triangular, shallowly fringed. integruiscula . 
Scales bifid, rudimentary. bifida. 
Cuscuta indecora neuropetala (Choisy) Hitchcock 
Distribution in South America: Venezuela, Brazil, and Paraguay. 
Specimens examined: Brazil: Maranham (Gardner 6068 in part). 
Paraguay: Asuncion (Lindman A 2325). 
Venezuela: Ciudad Bolivar (L. H. and Ethel Zoe Bailey 1255). 
Cuscuta indecora subnuda Engelmann 
Cuscuta indecora subnuda Engelmann, Trans. Acad. Sci. St. Louis 1: 502. 1859. 
Engelmann characterizes this variety as having an exserted capsule and 
short, divaricate styles. I did not see the type specimen nor any other 
that would seem to belong here. It is apparently a rare form.
