145] NORTH AMERICAN AND WEST INDIAN CUSCUTA—YUNCKER 55 



to reflexed, triangular-ovate, acutish; scales scarcely reaching the filaments, 

 fringed, bridged at about a quarter of their height; stamens about equalling 

 the lobes; anthers oval-oblong, about equal to the somewhat subulate 

 filaments; ovary globose; styles slender, rather longer than the ovary. 

 Capsule globose, glandular, thin, not thickened but somewhat verrucose 

 at the top; styles slightly tapering towards the base; seeds two to four 

 in a capsule, about 1.5 mm. long, roundish, compressed, somewhat rostrate; 

 hilum small, depressed. 



Type locality: Chile. Type not seen. Range in North America: 

 Scattered across the continent, mostly on Medicago sativa. 



Specimens examined: United States: Maryland; near Baltimore (Hillman). 5. 

 Dakota; White River (Over 2355). Texas; Sanderson (Wooton in 1911). California; Kern 

 Co. (Palmer 149), lower Sacramento (Jepson in 1893), Santa Cruz Mts. (Davis in 1908).

Cuscuta decipiens n. sp. 

 [Figures 43, 93 and 95] 



Stems slender. Flowers about 3 mm. long, glabrous, pentamerous, 

 subsessile or on pedicels as long as or slightly longer than the flowers; 

 calyx lobes ovate, obtuse, somewhat shorter than the corolla tube; corolla 

 campanulate, its lobes triangular-ovate, somewhat serrate, obtuse, or 

 acute with an inflexed tip; scales as long as or shorter than the tube, deeply 

 fringed, slightly spatulate, bridged at about a third of their height; stamens 

 shorter than the lobes; filaments about equal to the oval anthers; ovary 

 globose, slightly umbonate; styles slender, shorter than the ovary; stigmas 

 capitate. Capsule globose-oval, slightly umbonate, with the withered 

 corolla about it; seeds usually one or two in a capsule, about 1.7 mm. long, 

 light brown or yellow, rostrate or hooked ; hilum linear, oblong, oblique or 

 transverse, the umbilical area scarcely contrasted with the rest of the seed. 



All parts of the flowers are white or reddish and covered with numerous 

 whitish pellucid glandular-appearing cells. This species resembles C. 

 indecora, but is distinguishable by its obtuse calyx lobes, less fleshy and 

 smooth flowers, with scales which are ordinarily shorter, as well as by the 

 capsule which is not thickened as much at the apex. 



Type locality: Hacienda de Cedros, Zacatecas, Mexico. Range: 

 Central Mexico. 



Specimens examined: Mexico: Zacatecas; Hacienda de Cedros (Lloyd 193, the type,
