 undulate-margined; flovt'ers small, in axillary umbels of 3-4, on short pedi- 

 cels ; calyx U-2" long, campanulate, the ovate acutish lobes twice longer 

 than the tube, enlarging in fruit and equaling the capsule ; corolla 3" long, 

 blue or purplish, plicate in aestivation, scarcely at all dilated above, the lobes
