4(3 ART. i. — A. YASUDA : ON THE 



saiivus, C. Jlelo and Cucurbita Pepo, wliere the sclerenchymatous 

 sheath is wanting, they are found in the outer part of the pericarp- 

 tissue (PL V. Fig. 60). 



Fare)} {huma of the unter Part, The parencliymatous 

 cells which fill up the intervascular spaces are of enormous size, 

 and the intercellular spaces among them are also remarkable. 

 Especially, as we proceed to the inner part of the fruit do we 

 find larger parenchymatous cells touching each other very slightly. 

 In Mclothrla japonlca the parenchymatous cells are transversely 

 and tangentially elongated, and in 3Iomordlca Cliarantia they are 

 transversely and radially elongated. 



The structure of the innermost part of the fruit is often 

 difïërent from that of the other parts. In Actinosiemmu rucemosu///, 

 Scltizopepon bryon'ucfoUus, vur. japon icus and Gymnostenima 

 cissoldes the innermost part of the fruit contains large intercellular 

 spaces, which are most marked in Aclinosleinma racemosuin, where 

 the parenchyma presents a reticulate appearance.

 being the largest (the major axis being 0.022 mm. long and the 

 minor axis, 0.017 mm.), showing an irregular shape and a tuber- 

 cular surface, while those of the other s^iecies are round and 

 smooth. The quantity of the starch-grains in the fruit attains 

 its niaxinuun in Jlelothria j((poiiica and Gyninodeumia eissoides.
