 and the Archipelago, and extending to the New Hebrides.

Commelina nudiflora, Linn. ; Clarke in DC. Monogr. Phanerog., iii. p. 144. 



Timor Laut. — As circumscribed by Clarke, this is generally diffused in warm countries, 

 including Polynesia. The synonymy is very copious, embracing the names Commelina 

 pacifica, Vahl, Commelina cajennensis, Rich., and Commelina agraria, Kunth. A second 

 species was collected in Arrou. The genus numbers about 100 species, several of them 

 having a wide range, like the present.

 Flagellaria indica, Linn. 



Flagellaria indica, Linn. ; Miq., Fl. Ind. Bat., iii. p. 249 ; Benth., Fl. Austr., vii. p. 10. 



Arrou ; Timor Laut. — A climbing shrub, exceedingly common, especially in maritime 

 districts, in Tropical Asia, Africa, including the Mascarene Islands, and Australia. There 

 are also specimens in the Kew Herbarium from New Ireland and the Solomon Islands, 

 but it does not appear to reach Eastern Polynesia, where, in the Fijis and Samoa, it is 

 replaced by the only other species of the genus, Flagellaria gigantea, Hook, f., in Hook. 

 Ic. PL, t. 1429. 



PALM^E. 

 Calamus spp.

 Archipelago, are in the collections. Nearly 200 species are known, mostly inhabiting 

 Tropical and Subtropical Asia ; a few only Tropical Africa and Australia.

Arrou ; Ki. — The cocoa-nut is essentially a littoral palm, though it will grow inland, and 

 it is now found on nearly all tropical sea-coasts, including Polynesia. Where it originated
