34 ART. 4. A. YASUDA : ON THE 



Collenchytiia. At the proximal portion of the tendrils we 

 may distinguish three varieties of coUenchyma according as it is 

 developed : (i.) on all sides of the tendrils, (ii.) on the outside 

 of each fibro-vascular bundle, and (iii.) outside of each flbro- 

 vascular bundle as well as of each medullary ray. The first 

 variety is found in 3Ieloihria japonica, Oucumis saiivus, 0. Melo, 

 Triohosanihes cucumeroides, T. japonica, T. multiloha, Gymnostemma 

 cissoides ; the second, in Actlnostemma racemosum, Schizopepon 

 hrgoniœfoVras, var. japonicus, 3Io7nordica Charantia^ Luffa cyUndrica, 

 L. acutangula, CUrullus vulgaris and Lagenaria vulgaris ; the 

 third, in Benincasa cerifera and Cucurbita Pepo. In the distal 

 portion, the collenchyma masses on the under side of the tendrils 

 fuse into one another, 



Sclerenchyma, At the proximal portion of the tendrils the 

 sclerenchyraa forms a continuous ring.'^ At the distal portion, 

 however, it is developed only on the ventral side of the tendrils.^^ 

 In Benincasa cerifera and Lagenaria vulgaris the sclerenchyma 

 masses occur separately outside of each fibro-vascular bundle near 

 the base of the tendrils, and those masses which are on the ventral 

 side of the tendrils at the distal portion towards their apex, are united.
