only. Here, then, morphological modification for physiological 



work is graphically presented. But, small though on first sight 



the flower parts appear to be, the organs of each are quite 



evident, and appropriately 



displayed on one side are 



three flowers just pushing 



off their cap-shaped corollas. 

 Here is a terminal shoot of 



the common woodbine {Loni- 



cera grata, Fig. i).^ Three 



days ago it was gathered and 



placed in alcohol at 12.30 



P.M., but had it been intended 

 as a permanent specimen, it 

 would have been collected at 

 7.30 to 8.00 P.M. The reason 

 is, that while the one now 

 shown illustrates well the 

 floral relations of irregular 

 Caprifoliads, at the time 

 stated it further shows the 

 earliest stage in the pro- 

 cess of flower pollination by 

 moths. But even this de- 

 serves study from that stand- 

 point. 



It may be necessary for 

 some forms that not only 

 careful selection but special 

 treatment be resorted to. A 

 case in point is the Corpse 

 plant {Monotropa uniflora) 

 that is saprophytic, and abun- 

 dant in the woods of the Eastern States. The two speci- 

 mens exhibited were selected four days ago. Both are in- 

 structive as showing some of the buds and open flowers with
