Common throughout Viti (Seemann! n. 81; U. S. Expl. Exped.). Also collected in the Society, 
Tongan, and Samoan Islands, in New Caledonia (Sir E. Home!), the East coast of New Holland 
(Sir J. Banks !), and Borneo. : 
À very common and variable species, often attaining a considerable height, and yielding useful timber. 
In Viti it is known by the name of “Doi” (= “Toi” of Tahiti), and flowers about May, and hence that 
month, or the time thereabouts, is termed the “ Vula i doi,” or * Doi-moon." ;

My specimens are in fruit only, as were those collected by the United States Exploring Expedition. 
Until the flowers shall be known, it is best retained as a distinct species; but it looks to me very much like 
a variety of G. microcarpa, DC.

Only an imperfect flowering specimen of this was collected by the United States Exploring Expedition. 
.* 
On the mountains of Namosi, Viti Levu, I collected the foliage of a large tree (n. 84), which I have 
provisionally referred to Rhamnee, because the habit is somewhat like that of the Order. I have not been 
able to find anything like it either at Kew or the British Museum.
