Dec, 1922] YUNCKER SOUTH AMERICAN SPECIES OF CUSCUTA 
This species is closely allied with C. odorata and is frequently confounded 
with it, but differs from that species in the possession of a longer corolla 
with comparatively shorter lobes, and large, subsessile or sessile anthers. 
Type locality: Valparaiso (?), Chile. Distribution: Principally in central 
and northern Chile, two specimens from Argentina, one from Peru, and 
one from Brazil having been seen. The specimens found outside of Chile 
appear typical in all respects. A penciled notation on the Brazilian speci- 
men in the herbarium at Kew, apparently by Engelmann, expresses doubt 
as to that specimen's being from Brazil. 
Specimens examined: Argentina: (Lorentz 274) ; Prov. Mendoza (Smith in 1890-91). 
Brazil: (Sellow).

Stems medium. Flowers 4-6 mm. long, and nearly as wide in some 
specimens, subsessile in dense, lateral clusters; calyx shorter than, or 
mostly about as long as, the corolla tube; lobes ovate-orbicular, frequently 
unequal, obtuse, overlapping; corolla campanulate; lobes upright or 
spreading and in some flowers reflexed, about as long as the tube in most 
specimens, rarely about half as long, ovate, obtuse, overlapping; stamens 
reaching to about the middle of the corolla lobes, or shorter, filaments stout, 
subulate, and longer or shorter than the oval anthers; scales large and 
prominent, about reaching the stamens or, rarely, shorter, densely fringed 
with medium to short processes, bridged at the middle or below; styles 
subulate, about as long as, or shorter than, the depressed-globose ovary. 
Capsule depressed-globose, circumscissile, carrying the withered corolla 
about it; seeds about 2 mm. long, hilum linear. 
The length of the corolla lobes in comparison with the tube varies 
considerably with the different specimens, as do also the shape of the 
scales and the length of the styles. 
Key to the Varieties 
Corolla lobes about as long as the tube typica. 
Corolla lobes half to two thirds as long as the tube
