119] NORTH AMERICAN AND WEST INDIAN CUSCUTAYUNCKER 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 tj^e, 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.
