 dark blue; corolla club-shaped: seeds winged on one 

 side according to Grisebach. but Gray says not winged.

 15:174 (poor). — The pictures cited all show a salver- 

 shaped corolla. "Requires a soil that is peaty, or at the 

 very least porous and cool, well drained, and capable of 

 retaining an abundant supply of moisture, although it 

 may be fully exposed to the sun. In the alpine garden 

 here we grow them in pure sphagnum moss on a wall 

 facing due south, but the plants which we raise for sale 

 are grown in pots in a compost of sphagnum, heath-soil 

 and sand. Finest of Group III." Correvon.
