considering that thirty per cent, of the Australian, and about 
6-5 per cent, of the New Zealand genera are endemic. Ten 
of the forty-six genera of flowering plants in Juan Fernandez 
are endemic. In St. Helena the numbers are, total, twenty- 
six and five endemic ; and in the more extensive Hawaiian 
flora fifteen per cent, of the genera are endemic. I may 
add that the Australian and New Zealand outlying islands 
generally have very few endemic genera ; whereas New 
Caledonia’s remarkably rich flora abounds in endemic genera. 
Of the Howe Island genera 151, out of 160, are Australian ; 
ninety-nine are represented in New Zealand, and sixty-four in 
Norfolk Island — the last number probably too low. But the 
most remarkable fact is that no fewer than 134 of the genera 
reach the sixth column of the table, which means that they 
extend in some direction, or directions, beyond the Austra- 
lasian, Polynesian, and Malay Archipelago regions — these 
regions taken in their widest sense. Some of the genera, 
indeed many of them, are of world-wide range ; but I do 
not intend following up their full distribution. What is 
more remarkable, is the smallness of the number of purely 
Australasian genera, which do not exceed a dozen ; they 
are : Hymenanthera , a shrubby genus of Violaceae ; Lagunaria 
(Malvaceae) ; Melicope (Rutaceae), but this also extends to 
Polynesia ; Carmichaelia (Leguminosae), otherwise restricted 
to New Zealand ; Acicalyptus (Myrtaceae), New Caledonia 
and Fiji; Cassinia . Br achy come, and Ole aria (Compositae) ; 
Notelaca (Oleaceae) ; Lyonsia (Apocynaceae) ; Westringia 
(Labiatae) and Dichelachne (Gramineae). It will be noticed 
that the specially characteristic Australasian genera are not 
represented in Howe Island. 
Respecting other genera, I may mention that the sup- 
posed African Myoporum has been described as a new genus 
(Zombiana) by Baillon, and the Madagascar plant referred 
to Exocarpns turns out to be Leguminosae, — Phylloxylon , 
Bailh, Neobaronia , Baker. Ficus is not represented in New 
Zealand, and, so far as is known, not in Norfolk Island. 
It is also worthy of note that the world-wide genus J uncus
