54 ART. J. — A. YASUDA : ON THE 



Melo, and the iiiaiii axis of the tendrils of Cifcuröita Fepo, 

 Ben'inrasa cerifera, Luffa aculanguh, Scliizopepon bryoniœfolius, 

 vor. japonicits are equally furnished with a central hollow. 



18. The number of stomata found on the tendrils is nearly 

 the same in all species. The number of fdjro-vascular bundles 

 varies from four {Ädhiostenuim raceinosu/ii, GyiimosieHuna cissokles) 

 to ten {Luffa vyUndriva). 



19. In the old roots of Moinordica Cliarantia the fibro- 

 vascular bundles have a double arrangement at the angled portions, 

 as in the old stems. 



20. The young roots of Actinosieiuma raceutosu/u have 

 remarkably wide intercellular spaces, the cause of which is to 

 be found in the habitus of the plant. 



21. Tubers are confined to Trivhosanthea cucuuieroldeSf T. 

 japonica and T. niuH'doba. The largest starch-grains contained 



in the roots are those of the tuber of Trichosanthes uiuUiloba 

 (0.042 mm. in diameter). 



22. The epidermal cells of the fruit may be radially 

 flattened, cubical, or radially elongated. Cucumis salivus is 

 characterized by having the epidermal cells four times longer 

 radially than tangentially ; and Benlncam cerifera, by having a 

 tangential septum in many of them. 



23. In the pericarp-tissue a sclerenchymatous ring, either 

 complete or incomplete, is generally formed. In Scliizopepon 

 bryonid'folius, var. japoriicus, Cucuinh saiivus, 0. Melo and 

 Cucurblla Fepo, however, it is entirely absent. 



24. The surface of the fruit of Actinosieinina raceinosum, 

 Mo/nordica Gkarantht and Cucumis sali vus is raised into tubercles. 

 The origin of the tuljercles varies ; for those of Actinostemma 

 niceiiiusi/iit and Mouiordica Ckaranlia are anatomically proved to be
