Mr. Bentham in his “ Flora Australiensis” includes the names of the plant- 
species of Lord Howe Island under the provincial heading of New South Wales ; 
and so also does Baron Sir F. von Mueller in his “ Census of Australian Plants,” 
adding, however, those of Norfolk Island. I do not know if the attachment of these 
insular floras to New South Wales be intended as an expression of their geographic 
relationship, or whether it be from the circumstance that the two islands are under 
the governmental jurisdiction of that colony. Political dependency cannot influence 
or determine botanical correlation ; and even if the floras of these islands have a 
decided continental facies, it would be desirable, on account of geographic isolation, 
to keep them distinct. But the main contention is, however—are the floras 
Australian; and, if not, to what region of the Australasian Province do they 
belong ?
