7. The number of libro-vascular buiullcs in tliu hypocotyls 

 is generally six, except in Citrullas vulgaris and Cacurhlla Pcjto, 

 the former of which has twelve, and the latter ten. 



8. The epidermal cells on the upper surface of the blade 

 of Trlclioianthes cucumeroldes are raised into conical papilke 

 pointing outwards. 



9. The epidermis of the blades may be many-layered as in 

 Cucurh'iia Pepo, a character which is limited to this species. 

 3Iomordic(i Chardiii'ia contains globular cystoliths (O.OGomm. in 

 diameter) in the greatly enlarged epidermal cells on the lower 

 surface of the blade. They are united into groups. 



10. Stomata on the npper surface of the blades are rarely 

 found in ^romordlca Charantia, Trichosanthcs japonica and T. 

 muHilobf, while they are entirely wanting in Schizopepo7i hnjo- 

 nurfoVins, var. japonicus and Gymiiostemma cUso'ules. 



11. The pallisade parenchyma is usually confined to thrce- 

 or four-tenths of the thickness of the blades, but sometimes 

 exceeds six-tenths in Cucurbita Pepo, where the pallisade cells 

 may be arranged in double rows. 



12. The fil.)ro-vascular bundles of the mid-ribs Jiear tlie 

 ])roxinial portion of the blades are arranged in six ways : the 

 first type has a single bundle situated at the centre of the mid- 

 ribs [Aclinostemma raceniosam, Schizopepon hryoïiiœfoUus, var. 

 ja2Joniciis) ; the second has two bundles overlapping each other 



{3Iclothria jajoonica) ; the third has three bundles, a larger one 

 at the centre, the other smaller two on each side and above 

 [Gymnostemma clssoides) ; the fourth also has three bundles, but 

 they are arranged perpendicularly {Cacumls sali vus, ('. Melo, 

 Benincas<i cerifcra, Lagenaria vulgaris) ; the fifth has four 

 Ijundles, and is di.Aiuiiuished from the third In' haviuir one more
