Arrou ; Timor Laut.— Generally spread in warm countries, including many of the 

 islands of Polynesm. Bidens bvpinnata, Linn., reduced by Hooker to a variety of .he 

 present species, also occurs in Timor Laut. Bidens is a considerable genus, and the 

 species are spread over all tropical, and nearly all temperate regions.

Timor Laut.— Common throughout India, " but no specimen seen from the Malay 

 Peninsula " (Hooker) ; also in Tropical Africa, and in America, where it is probably a 

 colonist. There are three or four other species of the genus which are all in Tropical 

 Asia, and one extends to Australia.

Arrou ; Timor Laut ; Letti ; Lakor. — A maritime shrub, common on the shores of 

 Tropical Asia, North Australia, and Polynesia. Nadeaud, however, states that it did not 

 exist in Tahiti in his time, and Mann does not include this species in his enumeration of 

 the plants of the Sandwich Islands (Proceedings of the American Academy of Arts and 

 Sciences, vii. p. 187) ; but Seemann records it from the Sandwich Islands, and, if we include 

 Sccevola sericea, Forst., which is probably only a hairy state of Sccevola koenigii, and a 

 parallel instance of what occurs in the West Indian maritime genus Borrichia (see Part 

 I., p. 45), it is plentiful there. 



The genus Sccevola comprises about sixty species, whereof fifty occur in Australia, 

 where forty-nine of them are endemic. A few species are restricted to Polynesia, chiefly 

 to the Sandwich Islands; and there is one species, Sccevola lobelia, Linn., which is 

 common on the sea-shores of Tropical Asia, Africa, and America, and also occurs in the 

 Galapagos, and in the Bermudas, but neither in Australia nor in Polynesia.

 order, inhabiting mangrove swamps in Timor and North-eastern Australia. There is a
