 interrupted, the pairs of flowers quite regularly separated by internodes 2-4 cm. long :

 on the stem. Stems 5-12 dm. tall, widely and loosely brandling : leaf-blades various, those 

 of the lower leaves 1-2-pinnatifid, ovate or ovate-lanceolate, 10-15 cm. long, those of the 

 upper leaves oblong to oblong-lanceolate, entire or some of those about the middle of the 

 stem serrate : pedicel slender or filiform, longer than the calyx and sometimes surpassing the 

 spreading or reflexed bracts : calyx-lobes linear or nearly so, longer than the tube : corolla 

 3-3.5 cm. long : capsules ovoid, 1-1.5 cm. long.
