Atlantic North American biennials or annuals; with mostly showy rose-colored of 

 white flowers (in summer and autumn), terminating the branches or in cymes. 

 Calyx in most species deeply parted. Corolla usually with a yellowish or dis-

 of the flower (and sometimes spirally twisted), later erect and its branches or 

 stigmas diverging. Seeds very numerous and small, globular, pitted.
