For comparison the amount of transpiration of the few cultivated

Nicotiana tabacum 1.547 0.561 2.018 



Zea Mays 1.607 0.427 2.034 



Pisum sativum 2.400 0.809 3.209 



ViciaFaba 2.877 L211 4.088 



Helianthus annuus 3.738 "1.116 4.854 



Thus we see the amount of transpiration from the surface of the leaf 



of Neluuibo nucifera is remarkable and much greater than that of the 



land plants. 



In closing I wish to express my hearty thanks to Prof. Dr. Miyoshi 



for his kind criticism.
