cortex. These extra-phloem sieve-tubes occur in the hypoderma outside 

 of the stiffening ring. And when no stiffening ring is present they are 

 found in the outer part of the cortex. 



(21) We may distinguish three kinds of the epidermal cells of the 

 seeds : a) flattened cells, b) prismatic cells, c) prismatic cells with ridges 

 on their walls. To the first type belong Actinostemrna, Gymrw&emma, 

 and Trichosanthes japonica ; to the second Benincasa, Luff a, Momordica, 

 and Trichosantltes cucumeroides ; to the third Citndlus, Cucumis, Cucur- 

 bita, Lagenaria, Melothria, and Schizopepo7i. 



In conclusion I wish to express my hearty thanks to Prof. Dr. 

 J. Matsumura, under whose care I conducted my investigations. I am 

 also very thankful to Mr. Y. Tanaka, Dr. K. Miyabe, Mr. T. Makino, 

 and Mr. T. Yoshinaga, who kindly gave me valuable materials.
