PLATE 36 
Top of an unopened intemode in a stem of Ricinus communis next under one that 
had sealed into it a tube containing o. 2 c. c. of a 20 per cent solution of monobasic 
ammonium phosphate. It shows a thickened cone and nodular proliferations from 
its apex. The white patches in the pith are dead cells and below the surface here 
shown they are united. In cross section at the extreme left are the vascular bundles of 
the node showing as dark spots (V 7 ?) and above and below as strands. Experiment 
begun August 21, 1916. Photographed on September 5. X5.
