 rarely whitish ; upper petals sometimes yellow, with blue 

 veius, lower ones white-bearded ; sepals nearly equaling 

 the spur : follicles 3-t, very long, becoming glabrous, 

 strongly diverging ; seeds smooth. May. Northern

 ceolate lobes ; petioles hardly dilating at the base : fls. in 

 simple, conical racemes ; sepals blue, somewhat pubes- 

 cent outside, nearly equaling the spurs in length;

 probable that all or nearly all the plants sold here 

 under this name should be called D. exaltatum, which 

 is a closely allied species.
