Dec, 1922 J YUNCKER SOUTH AMERICAN SPECIES OF CUSCUTA 
Stems medium. Flowers 4-5 mm. long and nearly as broad, texture 
thick and fleshy, sessile in few- to many-flowered, globular clusters, each 
flower frequently subtended by an ovate-orbicular bract, perianth segments 
commonly finely fimbriate with delicate filamentous processes; calyx deep, 
reaching nearly to the corolla lobes; lobes orbicular, overlapping; corolla 
urceolate; lobes ovate-orbicular, overlapping, about half as long as the 
tube, upright, becoming connivent in fruit; stamens short, filaments stout 
and shorter than the oval anthers; scales large, reaching the stamens, 
bridged at about the middle or below, fringed with short or medium-length 
processes; styles subulate, about equal to the globose, depressed ovary; 
stigmas elongated-globose or globose. Capsule depressed-globose, circum- 
scissile, with the withered corolla about it; seeds about 1.5 mm. long, two 
to four in each capsule, seeds in some capsules red, hilum short, oblong. 
Type locality: "Cuzco, Bolivia." Distribution: In western Bolivia and 
northern Argentina. 
Specimens examined : Argentina: Prov. de Catamarca, Dept. de Andalgala (Jorgensen 
1702). 
Bolivia: (Buchtien 113); Mt, (?) Cuzco (Pentland, the type, a fragment in the 
Engelmann herbarium); La Paz (Buchtien 753, 3235; E. W. D. and Mary M. Holway 
Mar. 25, 1920; Bang 115 in part; Rusby 2004); between Palca and La Paz (Pflanz j^^); 
Sorata (Mandon 1480, mixed with C. odorata in some collections; Bang 1304); Cotana 
(Buchtien 133, 4504)- 
9. Cuscuta boliviana n. sp. 
(PI. I, fig. 3, A~E) 
Stems medium to slender. Flowers 2.5-3 mm. long, subsessile or sessile 
in dense, few-flowered, globular clusters; calyx nearly as long as the corolla 
tube; lobes ovate-orbicular, obtuse, overlapping, infrequently some lobes 
strongly carinate, edges slightly uneven but not fimbriate; corolla campan- 
ulate, soon becoming somewhat globular about the developing capsule; 
lobes upright or spreading, ovate, obtuse, shorter than the tube; scales 
reaching the stamens, oblong, truncated, moderately fringed with medium- 
length processes particularly about the top, bridged below the middle; 
anthers about equaling or shorter than the stoutish filaments; ovary 
globose, slightly thickened about the style bases; styles stout and slightly 
subulate, shorter than the ovary; stigmas globose. Capsule depressed- 
globose, circumscissile, with the withered corolla about it but not covering 
the partly exposed capsule; seeds about 1.5 mm. long, ordinarily four in 
each capsule, reddish in the specimen examined, hilum short, oblong, oblique. 
This species is closely related to C. glohiflora but differs from it in having 
smaller flowers, spreading corolla lobes, partially exposed capsule, and 
shorter styles. Also the perianth segments are not fimbriate as in that 
species. It differs from C. cristata in the possession of a circumscissile 
capsule. 
Type locality: Padcayo, Bolivia. Distribution: Known only from the 
type locality. 
Specimens examined: Bolivia: Padcayo (Fiebrig 2^23, the type, in the Buchtien 
herbarium, a fragment in the author's herbarium).
