living together for mutual benefit) of plant and animal, showing that 

 there is here a true case of myrmec' >phily as in Acacia sphaerocephala 

 (q.v.}. These ants protect the C. from the leaf-cutter ants. The 

 internodes are hollow but do not communicate directly with the air. 

 Near the top of each however is a thin place in the wall. A gravid 

 ? ant burrows through this and brings up her brood inside the stem. 

 The base of the leaf-stalk is swollen and hears lood bodies (cf. Acacia) 

 on the lower side, upon which the ants feed. New ones form as the 

 old are eaten. Several other sp. show similar features. An interesting 

 point, that goes to show the adaptive nature of these phenomena, is 

 that in one sp. the stem is covered with wax which prevents the leaf- 

 cutters fn m climbing up, and there are neither food-bodies nor the 

 thin places in the internodes.
