Jan., 1923] YUNCKER — SOUTH AMERICAN SPECIES OF CUSCUTA 
7 
than, the subulate filaments; scales reaching the stamens, ovate, fringed 
with moderate processes, bridged at about the middle or somewhat below; 
ovary globose, styles slender and shorter than, or becoming longer than, 
the ovary, stigmas medium or infrequently large and convoluted. Capsule 
globose, with the withered corolla about it; styles becoming stoutish and 
sometimes slightly subulate, not circumscissile, thin towards the base; seeds 
two to four in each capsule, about 1.5 mm. long; hilum oblong, oblique. 
It is believed that what Progel described as C. platyloba is a smaller 
form of Engelmann’s C. racemosa calycina. The specimens here considered 
closely approach C. racemosa , but it is believed that they show characters 
that will allow of their being maintained as a distinct species. 
Type locality: “ Montevideo.” Distribution: Southern Brazil and 
Uruguay. 
Specimens examined: Brazil: Prov. Goyaz (Glaziou 21808) ; Prov. Rio de Janeiro (Ule 
3565; Glaziou 11279; Hillosen 2338); Prov. Santa Catharina (Pabst#p); Central Brazil

(PL V, fig. 31, A-E) 
Cuscuta stenolepis Engelmann, Trans. Acad. Sci‘. St. Louis 1: 503. 1859. 
Stems slender, densely matted. Flowers few and scattering, about 2.5 
mm. long, on pedicels as long as, or shorter than, the yellowish or infre¬ 
quently reddish, glandular flowers, in scattered, few-flowered, paniculate or 
cymose clusters; calyx deeply divided, reaching the middle of the corolla 
tube or nearly to the sinuses in some flowers, lobes ovate, obtuse; corolla 
subcylindrical, lobes about half as long as the tube, oblong-ovate, obtuse, 
reflexed, with inflexed tips; stamens shorter than the lobes, filaments equal 
to, or shorter than, the oval anthers; scales about reaching the stamens, 
bridged at a third or a quarter of their height, narrow, sparingly fringed 
with a few scattered processes; styles slender, about equal to the globose, 
apiculate ovary. Capsule globose or conic, with the withered corolla about 
the apex like a hood; seeds subglobose, about 1.5 mm. long. 
Type locality: Andes of Quito, Ecuador. Distribution: Known only 
from Ecuador. 
Specimens examined: Ecuador: Quito (Hall, the type, a fragment in the Engelmann
