PERFECT FLOWERS 53 



the Sarcophaga sarracenice, has even received its 

 name from the generic name of the plant. But we 

 have not yet done with the many-sided relations 

 which bind the pitcher-plant to the insect world. 

 For insects it is not only a reception room and a 

 tomb, but also a cradle. There is a moth called 

 "Pappaipema appassiona- 

 ta" which breeds in the root 

 of the Sarracenia. 



In addition to the flow- 

 ers described, the following 

 procure cross - fertilisation 

 by means of the stigma riTCIIER . PLANT 



placed well in advance of 



their anthers: huckleberry, sundrop, pipsissewa, 

 shooting star, Indian cucumber-root, early blue 

 violet, wintergreen and others. 



But spreading stamens and protruding pistils 

 are not the only variations possible in the positions 

 of those organs. A third, and most interesting, 

 combination has been effected to procure cross- 

 fertilisation in the so-called dimorphic flowers, 

 which we can best explain with some of the dainty 

 little Houstonias in our hands.
