Seeds more fimbriate than in C. eiiroptsa. Styles (in Engelmann's named examples of 

 C. plcmiflora) short, less than half as long as the stigmas. C. brenistyla is not 

 merely " too near " C, planiflora as both Engelmann and Boissier suggest ; it is the 

 same thing.

 sistent, often much enlarged. Corolla funnel-shaped campanulate, or rotate, 

 often plaited ; lobes 5 (in Datura sometimes 10), or limb subentire. Stamens 

 5, on the corolla-tute ; anthers ovate or oblong, dehiscing by apical pores or 

 longitudinally. Ovary 2-ceUed, or imperfectly 1- or 4-ceUed, in Nioandra 3-6-
