165] NORTH AMERICAN AND WEST INDIAN CUSCUTA—YUNCKER 75 



sides, bridged at about the middle or above; stamens shorter than the 

 corolla lobes; anthers elliptical to oblong, about as long as or shorter than 

 the filaments; styles capillary, longer than the somewhat flask-shaped 

 ovary. Capsule globose-pointed or flask-shaped with the withered corolla 

 carried at its apex; seeds about 1.7 mm. long, oval, globose, slightly com- 

 pressed, light brown, one or infrequently two in the capsule, or this not 

 infrequently sterile; hilum oblong, oval, transverse. 



This is undoubtedly the plant referred to by Rafinesque and named 

 C. aphylla by him. His name would be valid were it not that Loureiro in 

 1790 used aphylla to designate another plant of this group. It is rather 

 doubtful if the plant described by Rafinesque as C. paradoxa is the same 

 as this one.
