The comparatively long corolla tube is quite filled with 



the style, leaving no passage for the tongues of in- 

 sects. The nectar glands, however, instead of be- 

 ing at the base of the tubes as usual, are at the

At the base of the style in Diervilla there is a 

 large gland (a), the significance of which has not 

 been explained. In Lonicera there is a small gland

 the style (f). From this series of forms it seems clear that 

 the glands in Lonicera and Diervilla are really rudimentary 

 branches.
