Fl. Brit. Ind., iii. p. 638.

Arrou ; Ki ; Moa ; Dia. — A small tree inhabiting the coast region and salt-marshes of 

 Tropical Asia, Australia, and many of the islands of Polynesia, including the New- 

 Hebrides, the Tongan and Fiji Islands, and the Isle of Pines, near New Caledonia. 

 The large fibrous seed-vessel of this and the three or four other species of the genus, 

 which are also sea-shore trees, floats on the water, and is diffused by oceanic currents. 

 It is in the collection of drift fruits and seeds made by Mr Moseley. 



Ochrosia borbonica, Gmel. 1 



Ochrosia borbonica, Gmel. ? Hook, f., FL Brit. Ind., iii. p. 638. 



Arrou. — Imperfect specimens of an Ochrosia, probably of this species, which inhabits 

 the tidal forests of the Andaman Islands, Singapore, Java, Ceylon, the Seychelles and 

 Mascarene Islands. Another species was collected in Timor Laut, perhaps the Australian 

 Ochrosia elliptica, Labill. There are about a dozen species in the region indicated, some 

 of them extending to the Pacific Islands. Darwin collected one species, Ochrosia parri- 

 flora, Henslow, in the Keeling Islands, and the same one has since been found in Tahiti, 

 the Ellice, Samoan, and Fiji groups. 



Plumeria acutifolia, Poir. 



Plumeria acutifolia, Poir. ; Miq., Fl. Ind. Bat., ii. p. 426; Hook, f., Fl. Brit. Ind., iii. p. 641. 



Ki. — A tree of American origin, now commonly cultivated and widely naturalised in 

 India and the Archipelago. The genus, which numbers from thirty to forty species, is 

 wholly American, though several species are now colonised in the Old World. 



Tabernsemontana parviflora, Dene. 



Tabernmmontana parviflora, Dene., Herb. Timor. Descr., p. 51.
