 cence narrowly thyrsoid-paniculate, often 12'

 lar-funnelform, the tube I'-i'A' long, slightly 

 thicker upward, the limb cleft into ovate or 

 lanceolate acute or acuminate spreading or re- 

 curved lobes; stamens unequally or about equally 

 inserted in the throat; ovules numerous; seeds 

 mucilaginous and emitting spiral threads when 

 wetted.

 the segments linear-oblong, sometimes toothed, 

 obtuse or acutish, 2"-6" long, those of the stem 

 alternate, smaller, the uppermost minute and 

 entire; flowers very numerous, small, panicu- 

 late, some sessile, some petioled; calyx 5-lobed, 

 the lobes lanceolate to ovate; corolla salverform, 

 3"-5" long, the limb violet or blue, its white 

 tube longer than the calyx and its obovate lobes; 

 stamens exserted; seeds not mucilaginous nor 

 emitting spiral threads when wetted.
