The tabular arrangement of the extra-Australian genera presents at a glance 
their geographic distribution, though it does not indicate their genetic relationships, 
which may very much modify any deductions drawn only from the former. 
The peculiar genus Ungeria has some affinities with He/zcteres, occurring in all 
warm regions, but is more nearly related to Reevesza of the Oriental region. 
The other endemic genus, S¢veélorrhiza, is closely related to Carmuchaelia, 
which contains one species each in Lord Howe Island and New Zealand. 
Procris is an Oriental genus extending to Papua and some of the Pacific isles, 
but is not yet known in Australia. 
Melicytus is peculiar to New Zealand, with the exception of the endemic species 
in Norfolk Island. 
Meryta is a larger genus than Melicytus and is essentially New Zealandian, but 
has two or three outlying species in Norfolk Island and the South Seas. 
Phormium is represented by two species inhabiting New Zealand, one of which 
extends to Norfolk Island. 
Rhopalostylis, H. Wendland and Drude. I have adopted the dismemberment of 
Kentia, as approved by Bentham and Hooker in their “Genera Plantarum,” if for no 
other reason than that it expresses tersely the inter-relations of the Australasian 
species of the composite genus Kentia. Thus Rhopalostylis is restricted to Kentia 
Baueri in Norfolk Island and A. sapida in New Zealand.
