the fruit of Benincasa cerlfera., Citndlus vulgaris und Cacurhita 

 Pcpo. In Benincasa cerifera it consists of bundles of rods crossing 

 one anotlier like a trellis, and presenting a reticular appearance.'' 



l*eri('ai'j>-f issue ivifhiii the JEj>fdevniis. The structure of 

 the pericarp-tissue Avitliin the epidermis is not uniform in all 

 species. Some fruits have a hardened ring in the outer tissue of 

 the pericarp (PL V. Fig. 61), while in others this is lacking (PL 

 V. Fig. 60). In Aclinoslemma raceniosum, Blelothria ja]}onica, 

 Luffa cyUndrica, L. acutangula, G'drullus vulgaris, Benincasa 

 cerifera, Lagenaria vulgaris, Trichosanihes cucumeroides, T. japo- 

 nica, T. multiloba and Gyumoslemnia cissoides the hardened ring 

 is developed, that of Aclinoste/inna racemoswii and Melothria 

 japonica being incomplete and interrupted in man}' places (PL 

 IV. Fig. 58) ; in ScMzopcpon, hrgoniœfolius, var. japonicns, Mo/nor- 

 dica Charantia, Gacumis sativus, C. Mclo and (Jacurhita Fepo the 

 mechanical sheath is entirely wanting. 



The sclerenchvmatous cells constitutinii the hardened rin«; 

 may be thin-walled with numerous pits, as in AciinosU'inuia 

 racciiiosuni, Melothria japonica and Benincasa cerifera, or may 

 be thick-walled with distinct })Ore-canals, as in Liifa cyUndrica, 

 L. acntangala, (Jitrullus ralgaris, Lagenaria vulgaris, Tricliosanthes 

 cucwneroides, T. japonica, T. iitultiloha and Gy)nnoslemma cissoides. 



The hypodermal cells lying outside of the hardened ring are 

 rather smaller than those of the deeper fundamental tissue, and 

 when no hardened ring is present the parenchymatous cells of 

 the outer part of the pericarp under the epidermis act as such. 

 In Lagenaria vulgaris and Benincasa cerifera the hypodermal
