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). 1 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 uniflord)

 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
