clusters; calyx lobes ovate to somewhat lanceolate, acute to acuminate, as 

 long as the corolla tube; corolla campanulate, shallow or somewhat 

 cylindrical; lobes as long as the tube, ovate to lanceolate acute to acumin- 

 ate, upright, sometimes spreading; edges of the lobes frequently some- 

 what uneven, more or less overlapping; scales narrow, oblong, shorter 

 than the tube, fringed with short processes, closely attached to the tube 

 for nearly their entire length, sometimes with only the attachment to the 

 filament fringed, bridged somewhat below the middle, or the scales reduced 

 to small wings; anthers oval, on equal or shorter subulate filaments; styles 

 slightly subulate, shorter than or equalling the globose, pointed ovary. 

 Capsule globose, pointed, usually one-seeded, surrounded by the withered 

 corolla; seeds about 1.5 mm. long, globose-ovoid, rostrate; hilum short, 

 oval, transverse. Commonly found parasitizing saline herbs.
