Moa. — The Water-melon exists in a wild and cultivated state in nearly all tropical 

 and many subtropical countries, but it is believed to be really indigenous only in 

 Tropical Africa. It is cultivated, and more or less wild, in many of the islands of 

 Polynesia, where, however, according to Seemann, it is known to have been introduced 

 by Europeans. 



Momordica charantia, Linn.

 Oliver, Fl. Trop. Afr., ii. p. 537 ; Seem., Fl. Vit., p. 105. 



Timor Laut. — Commonly cultivated and naturalised in tropical countries, and 

 probably indigenous in Tropical Africa. Seemann collected it in the Fijis, and he 

 mentions that it was collected in Tahiti by Banks and Solander. Momordica balsamina, 

 Linn., has nearly the same range as the present, and also extends to Australia. Both 

 species are regarded by Cogniaux (DC, Monogr. Phanerog., iii. pp. 437 et 440) as- 

 introduced in America.

The Calabash Gourd, generally cultivated for the fruit, which is not eaten, but used for 



making bottles, &c. It was found in Easter Island, the Sandwich Islands, and other 



parts of Polynesia, when first discovered by Europeans. 



Cucumis trigonus, Roxb. ? 



Cucumis trigonus, Eoxb. ? Hook, i., Fl. Brit. Ind., ii. p. 619 ; Benth., FL Austr., iii. p. 317 ; Miq., Fl. 

 Ind. Bat., i. 1, p. 671 {Cucumis turbinatus). 



Timor Laut.— Generally diffused in Tropical Asia and extending to North 

 Australia. 



Zehneria sp. (aff. Zchnerioe mucronatce, Miq.) 



Timor Laut. — The species may be different from the Java plant. Zehneria, as 

 circumscribed by Bentham and Hooker, is confined to the Old World, with the exception 

 of one species in Peru.
