cemes numerous, erect or nearly so, densely flowered: pedicels mostly 
shorter than the fruit, at length reflexed : corolla short-funnelform, blue or

from blue to nearly white or pinkish, rotate, its tube shorter than the calyx 
and the lobes, the limb 4-6 lines in diameter: dorsal disk of the nutlets 
triangular-ovate, obscurely carinate, rough-tuberculate, and with a few
