There are several undeterminable specimens in the collection. One 

 of them, consisting of foliage only, from the mountains of Tahiti, 

 probably belongs to one of the four still undescribed species of Cucur- 

 bita of Solander, enumerated by Forster at the end of his Prodromus. 

 Two others, from Luzon, are apparently species of Bryonia, but too 

 imperfect for determination. 



Lagenaria vulgaris was found in cultivation at all the larger Pacific 

 Islands. 



Cucurbita Aurantia ? the " Arroro" of the Tahitians, is said to 

 grow in mountain woods at Tahiti. Probably it is one of the species 

 enumerated by Solander. There are no specimens in the collection.

Hab. Organ Mountains, Brazil : where it was also collected by 

 Gardner (No. 607), and by Pohl. 



The late Dr. Gardner says of this species : " This is one of the most 

 handsome of the genus I have yet met with. It grows in rather wet 

 places in the virgin forests, and reaches sometimes to the height of 

 fourteen or fifteen feet. April, 1837." — Gardn. in herb. Hook. Only
