 rarely whitish ; upper petals sometimes yellow, with blue 

 veins, lower ones white-bearded; sepals nearly equaling 

 the spur : follicles 3—4, 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-

 — A polymorphous and complex species of Europe. It is 

 probable that all or nearly all the plants sold here 

 under this name should be called D. exaltatum, which 

 is a closely allied species. 



17. grandifldrum, Linn. (D. 5i«^nse, Fischer). Figs. 

 685-6. Stem rather slender, 2-3 ft. high: Ivs. rather
