Chapter V — 89 — Cephalotus 



with insects. In view of the work of Busgen (Utricularia) and of F. 

 Darwin (Drosera) he does not exclude a "carnivorous tendency." 

 On the whole, therefore, at the present moment, the evidence favors 

 the view that both the secretions of the pitcher and the action of 

 bacteria contribute to the breaking down of proteins making the 

 products available to the plant. Experiments with starch showed no 

 evidence of the presence of diastase.
