119] NORTH AMERICAN AND WEST INDIAN CUSCUTA—YUNCKER 29 



clusters; calyx deeply divided, shorter than or equalling the corolla tube; 

 lobes ovate, acutish, thickened along the mid-portion of the dorsal surface 

 which bears a short projection near the apex; corolla cylindrical, slightly 

 baggy in the basal region; lobes shorter than the tube, somewhat over- 

 lapping, erect to spreading, ovate, acutish, with a prong-like dorsal pro- 

 jection near the apex; scales very small, reaching not more than the middle 

 of the tube, oblong, with a few short processes at the truncated apex, 

 scarcely bridged; stamens shorter than the lobes; filaments shorter than 

 the somewhat oval, subsessile anthers; styles subulate, as long as or shorter 

 than the small, globose-conic ovary; stigmas capitate. Not seen in fruit, 

 but this quite evidently circumscissile. 



This species resembles C. corymbosa somewhat but differs in its more 

 deeply divided calyx and subulate styles. 



Type locality: Near Lake Chapala, Jalisco, Mexico. Range: Known 

 only from the type location. 



Specimens examined: Mexico: Jalisco; mountains near Lake Chapala (Pringle 5349, 

 the type, in the U. S. Nat. Herb, as sheet 305,846). 



Subsection lepidanchopsis n. subsect. 



Flowers sessile in compact more or less continuous clusters, subtended 

 by numerous bracts; calyx lobes nearly distinct, obtuse. 



Only one species has been found so far in this section. Some specimens 

 are quite similar in habit to C. glomerata. 



Cuscuta pringlei n. sp. 

 [Figures 13, 119 and 152] 

 Stems medium. Flowers glabrous, subsessile to sessile, about 4 mm. 

 long, pentamerous, compacted into dense elongated clusters about the 

 host plant much as in C. glomerata or more loosely paniculate; flower 

 parts somewhat fleshy; calyx segments slightly united, ovate, cupped, 

 appressed to the corolla, overlapping, subtended by several unequal bracts 

 of much the same shape as the calyx lobes; edges of the bracts and calyx 

 lobes slightly irregular and the thickened median portion reddish; corolla 

 campanulate, lobes, oblong-ovate, spreading, about as long as the tube 

 and with the edges slightly uneven; scales ovate, reaching the filaments, 

 copiously fringed with medium length processes, bridged at or slightly 

 above the middle; stamens shorter than the lobes; anthers oblong, about 

 as long as the filaments; ovary globose-conic, becoming umbonate; styles 

 longer than the ovary, exserted in fruit. Capsule umbonate, thickened 

 at the apex, circumscissile with a slightly jagged edge leaving the obcordate 

 dissepiment in the persistent calyx; seeds usually three or four in a capsule, 

 about 1.5mm. long, angled, oval or roundish, light brown or chocolate 

 brown, mottled?; hilum short, oblong, oblique to transverse or reduced to a 

 roundish dot.
