 Tthas been suggested that the pitcher plant moths (Exyra) 
may be pollenizers of these flowers ; but as fava at Summer-

es most intimately associated with it, does not appear 
i the middle of May, and Exyra semicrocea not until the 
middle of April, this can scarcely be the case. The color of 
the flowers and the fact that their fragrance becomes more

flying may aid in pollination. The following list in-
