Three new species, Licuala cabalionii, Calamus<br />
aanuatuensis and Cyphosperma aoutmelense, are<br />
described from <strong>Vanuatu</strong> as a precursor to a revision<br />
<strong>of</strong> the palm flora.<br />
<strong>Vanuatu</strong> (formerly the <strong>New</strong> Hebrides)<br />
is an archipelago <strong>of</strong> about 80 small to<br />
moderate-sized volcanic and coral-based<br />
islands orientated linearly north-west to<br />
south-east between l3oS and 22oS and<br />
l65oE and 170"E in the southwest Pacific<br />
Ocean. The closest neighboring land mass<br />
(I6,L92 sq km) is la Grande Terre <strong>of</strong> <strong>New</strong><br />
Caledonia, which is about 500 km to the<br />
southwest. The scattered southern islands<br />
<strong>of</strong> the Solomon Islands, <strong>of</strong> which San Cristobal<br />
is the largest at 4,200 sq km, are<br />
about 600 km to the north while the Fiji<br />
Islands lie some 1,200 km to the east.<br />
Espiritu Santo, at 4,100 sq km, is the<br />
largest island in <strong>Vanuatu</strong>.<br />
Geologically much <strong>of</strong> <strong>Vanuatu</strong> is <strong>of</strong><br />
recent (Eocene and younger) age when<br />
compared with nearby terrains; both <strong>New</strong><br />
Caledonia and Fiji retain evidence <strong>of</strong> continental<br />
(Cretaceous) formation dating from<br />
the break-up <strong>of</strong> the continent <strong>of</strong> Gondwana.<br />
There are six active volcanoes and<br />
many semi-active areas within the <strong>Vanuatu</strong><br />
archipelago. Island-building is presently<br />
taking place because <strong>of</strong> uplift wrought by<br />
the convergence <strong>of</strong> tectonic plates.<br />
The flora <strong>of</strong> <strong>Vanuatu</strong>, in essence an<br />
extension <strong>of</strong> the floras <strong>of</strong> Malesia and <strong>New</strong><br />
Guinea, is not as well known as those <strong>of</strong><br />
some nearby island groups (e.g., Fiji and<br />
<strong>New</strong> Caledonia), as many <strong>of</strong> the remote<br />
and outlying islands (most <strong>of</strong> which harbor<br />
complex forests) have yet to be thoroughly<br />
botanized. P. S. Green (I979), while writing<br />
on the findings <strong>of</strong> the I97l Royal<br />
<strong>Society</strong> Expedition to <strong>Vanuatu</strong>, noted an<br />
unexpectedly large number <strong>of</strong> plant species<br />
which were recorded for the first time<br />
in <strong>Vanuatu</strong>, particularly species from the<br />
Solomon Islands, <strong>New</strong> Caledonia, and Fiji.<br />
Of those regional affinities which have been<br />
ascertained, that with the Fiji Islands (even<br />
though they are considerably farther away<br />
than either <strong>New</strong> Caledonia or the southern<br />
Solomon Islands) is the most obvious<br />
(Schmid 1966).<br />
The affinity <strong>of</strong> the palm flora displays<br />
the same trends as does the flora in general<br />
(i.e., in a broad sense an extension <strong>of</strong> the<br />
Malesian and <strong>New</strong> Guinea floras and in a<br />
regional perspective having a close relationship<br />
with that <strong>of</strong> the Fiji Islands)<br />
(Schmid 1966, Chew Wee-Lek 1984,<br />
Dowe l99I), although in the northern<br />
islands, such as the Torres and Banks<br />
Croups, a shared distribution andlor close<br />
relationship with palm species from the<br />
southern Solomon Islands exists (the Santa<br />
Cruz Group <strong>of</strong> the Solomon Islands is geologically<br />
similar to the northern islands <strong>of</strong><br />
<strong>Vanuatu</strong>). An appraisal <strong>of</strong> the relationship<br />
between the <strong>Vanuatu</strong> and Fijian palm floras<br />
(Dowe l99l) recognizes that, despite<br />
there being only one shared species (i.e.,<br />
Cocos nucifera), rhe number <strong>of</strong> shared<br />
genera is relatively high, being in the order<br />
<strong>of</strong> seven <strong>of</strong> a total o{ fifteen. This is significant<br />
when it is considered that many<br />
palm genera which occur in the southwest<br />
Pacific are monotypic or have only a few<br />
species and that Fiji is a considerable distance<br />
away. Compare this to the number<br />
<strong>of</strong> palm genera shared with <strong>Vanuatu</strong>'s clos-

est neighbor, <strong>New</strong> Caledonia; only two genera<br />
(Cocos and Cyphosperma) <strong>of</strong> a combined<br />
total <strong>of</strong> 25 genera occur in both<br />
areas. Whether Vanualu was or is in a<br />
favored position to receive propagules from<br />
Fiji (i.e., abutting prevailing ocean currents,<br />
in the paths <strong>of</strong> migrational birds,<br />
etc.) has yet to be investigated, although<br />
the uniformity <strong>of</strong> the strand vegetation <strong>of</strong><br />
the region is evidence <strong>of</strong> ocean currents<br />
being a major influence on the distribution<br />
<strong>of</strong> plants in the southwestern Pacific (Gunn<br />
and Dennis 1976, Merrill l98l). Of the<br />
eight genera which are not shared, four<br />
are monotypic, three <strong>of</strong> which are endemic<br />
to Fiji.<br />

Solomon Islands and <strong>Vanuatu</strong>. The genus<br />
has developed its greatest diversity in Malay<br />
Peninsula and Borneo (about 50 species)<br />
and <strong>New</strong> Guinea (about 36 species)' Iicuala,<br />
was not recognized as occurring in<br />
<strong>Vanuatu</strong> until I970, when I. grand'is was<br />
collected from southern Espiritu Santo<br />
(Whitmore 1973). Erroneously this species<br />
had been documented in numerous<br />
publications as originating from <strong>New</strong> Britain,<br />
an island to the east <strong>of</strong> <strong>New</strong> Guinea,<br />
an error most probably originating from<br />
its initial description from a horticultural<br />
source.<br />
Licuala cabalionii is distinguished from<br />
the closest occurring species, L. grandis<br />

much <strong>of</strong> <strong>Vanuatu</strong> as well as the Santa<br />
Cruz Group and San Cristobal Island <strong>of</strong><br />
the Solomon Islands) by its divided leafblade,<br />
less spiny petiole, shorter floral pedicel<br />
and sparingly as opposed to multi<br />
ribbed endocarp. L. lauterbachii Darnmer<br />
& K. Schum. (Solomon Islands and <strong>New</strong><br />
Guinea) differs in having a short and erect<br />
inflorescence, red fruit' and irregularly<br />
divided leaf-blade.<br />
The known populations <strong>of</strong> L. cabalionii<br />
do not occur close to populations <strong>of</strong> Z.<br />
grandis although they occupy similar habitats.<br />
The former occurs in very dense<br />
colonies (almost monospecific) in primary<br />
rainforest; the forest floor in the vicinity<br />
is thickly cover with seedlings and small<br />
plants. I. grandis is much less gregarious,<br />
with very few seedlings being observed and<br />
individuals being relatively widely spaced.<br />
L. grandis is more commonly found in<br />
disturbed or secondary forest. No traditional<br />
uses or vernacular names have been<br />
recorded for L. cabaLionii.<br />
Licuala cabalionii has appeared as the<br />
manuscript names "Licuala sp. Vanua<br />

Discussion. Cyphosperma aoutmelen'<br />
se is most closely related to C. balansae<br />
from <strong>New</strong> Caledonia, from which it differs<br />
by its much smaller inflorescence, brown,<br />
scaly inflorescence branches, rounded and<br />
not prominent inflorescence branch bracts<br />
and smaller fruit. The two Fijian species<br />
are more distinct: C. tanga H. E. Moore<br />
has undivided or only apically divided leaves<br />
and a sparsely branched inflorescence while<br />

a distinct crownshaft, an infrafoliar inflorescence,<br />
