corolla lobes about equal to the corolla tube 
Floral parts mostly obtuse or slightly acutish or cuspidate, bracts 
few, stigmas globose 
Floral parts mostly acute, bracts more numerous, stigmas oval .... 
Scales mostly not reaching the stamens, moderately fringed with 
medium-length processes, corolla lobes shorter than the tube. . . . 
13. Cuscuta goyaziana n. sp. 
(PI. Ill, fig. 13, A-E) 
Stems medium. Flowers 4-5 mm. long, yellowish-orange in color, 
somewhat fleshy and thick in texture, with yellowish, pellucid, glandular-

The type of inflorescence is not known, for the specimens examined were 
represented only by parts of inflorescences. Calyx as long as the corolla, 
sepals distinct or nearly so, ovate, obtuse, overlapping; corolla cylindrical 
or somewhat campanulate; lobes ovate, obtuse or slightly acutish, about 
as long as, or somewhat shorter than, the tube, overlapping, spreading; 
stamens shorter than the lobes, filaments about as long as the large, oval 
anthers; scales prominent, exserted, bridged at about the middle, profusely 
fringed with long processes; styles slender, much longer than the globose 
ovary; stigmas globose. Capsule globose, circumscissile, with a thickened
